liquid insulator of electricity

The flexibility of porcelain material is another main reason behind its popularity. When water contains these ions it will conduct electricity, such as from a lightning bolt or a wire from the wall socket, as the electricity from the source will seek out oppositely-charged ions in the water. All you need is to send us the information about the desired design. Windings that use thicker conductors are often wrapped with supplemental fiberglass insulating tape. Whereas the positively charged electrode, i.e. Interestingly, if the water contains very large amounts of solutes and ions, then the water . When solid items heat, any internal gases and liquids also heat up. Conductors for lower voltages in distribution may have some insulation but are often bare as well. This makes them applicable to all types of the electrical power system. In the EU, double insulated appliances all are marked with a symbol of two squares, one inside the other.[7]. energy: The capacity for doing work; can be in many forms such as electrical, mechanical, chemical, sound, light and heat. The voltage capacity of the insulator also falls under electrical factors. At least, the vaporization of water in raw material. The ions flow about freely in this liquid substance and conduct heat and electricity. Conductor. IEC 60137:2003. Now lets move ahead and understand what happens when electricity passes in water. An Electrical Insulator has a porcelain shell. silicon dioxide, the primary component of glass. The insulator in the power system can also be used on the telephone pole. [1][2], In certain capacitors, shorts between electrodes formed due to dielectric breakdown can disappear when the applied electric field is reduced.[3][4][5][relevant?]. The Basics: An Introduction to Electricity and Electronics, Table of Electrical Resistivity and Conductivity, Delocalized Electron Defined in Chemistry, Ph.D., Biomedical Sciences, University of Tennessee at Knoxville, B.A., Physics and Mathematics, Hastings College. Suspension insulators can insulate conductors of up to 400KV. Apply this liquid for a skin-tight protective coating that insulates and resists moisture, acids, and corrosion. High voltage insulators for outdoor use are shaped to maximise the length of the leakage path along the surface from one end to the other, called the creepage length, to minimise these leakage currents. This was all about Electrical Insulators, properties and their types. Porcelain insulators are made from clay, quartz or alumina and feldspar, and are covered with a smooth glaze to shed water. The electrons present in the Electrical Conductor allow your phone to be fully charged. According to the credible power line accident statistics, many people get killed by getting into contact with the live power lines. Some of the common examples of Insulators are plastic, wood, rubber, and Ceramics. These parameters can be mechanical, physical, and electrical. Suspension insulator - For voltages greater than 33kV, it is a usual practice to use suspension type insulators, consisting of a number of glass or porcelain discs connected in series by metal links in the form of a string. A portion of the glass substance becomes liquid when heated. Silver is not always an ideal choice as a material, however, because it is expensive and susceptible to tarnishing, and the oxide layer known as tarnish is not conductive. 2. Sometimes conduction itself changes the temperature of a material. This helps to keep its insulation resistance high. When electricity passes through unclean water, consequences are fatal. Rigid foam boards trap air or another . Utility patent number 48,906 was granted to Louis A. Cauvet on 25 July 1865 for a process to produce insulators with a threaded pinhole: pin-type insulators still have threaded pinholes. In a solid, the breakdown voltage is proportional to the band gap energy. The four-piece insulator can even be used on 66KV conductors. I am not a scientist, this is purely theoretical concept t. It is always considered an alternative to strain insulator only that it has a lower capacity. The current-carrying conductors are covered with an insulator such as plastic. Electrical Insulators can withstand the charges from Electricity. (a) Distilled water (b) Silver nitrate (c) Sulphuric acid (d) Copper sulphate Answer Question 2. The first glass insulators used in large quantities had an unthreaded pinhole. Your Electrician uses a special screwdriver with a plastic coating to check the passage of Electrical charges without getting electrocuted. When subjected to a high enough voltage, insulators suffer from the phenomenon of electrical breakdown. springer Electrical breakdown is often associated with the failure of solid or liquid insulating materials used inside high voltage transformers or capacitors in the electricity . It is because these instruments do not have extremely high-voltage. Higher voltage transmission lines usually use modular suspension insulator designs. The glass is heat-treated so it shatters, making the damaged unit visible. High specific heat and thermal conductivity. There are several factors that can help you buy the best insulators for sale: This site is protected by reCAPTCHA and the Google Privacy Policy and Terms of Serviceapply. We know that under solids metals are the best electricity conductors. Keeping electricity bound within the material is the main goal of an . The conductor is suspended at the lower end while the other end is attached to the arm on the tower or pole. Steatite mountings are used. This negative anion loses an excess electron to the electrode and converts into stable oxygen gas. Metal grading rings are sometimes added around the disc at the high voltage end, to reduce the electric field across that disc and improve flashover voltage. Although all the insulators are meant to prevent the flow of electric current, their level of insulation tends to vary. The radiation breaks the molecules of the liquid apart into ions and then the ions diffuse through the liquid to carry a current. An electrical insulator is a material whose internal electric charges do not flow freely, . With the two terms, it simply means that glass will remain as a good insulator despite transmitting high current. In this guide, we are going to look at everything that you should know about high voltage power insulators. Simply defined, an electrical insulator is a type of material whose internal electric charges dont flow freely. The property that distinguishes an insulator is its resistivity; insulators have higher resistivity than semiconductors or conductors. SOLID DIELECTRICS LIQUID DIELECTRICS GASEOUS DIELECTRICS SOLID DIELECTRICS: EX: PVC, BAKELITE, MICA, PAPER, PORCELAIN, GLASS, . Materials that lack electron conduction are insulators if they lack other mobile charges as well. In transformers and capacitors, liquid Insulator oil is used for preventing arcs. In micro Electric components such as transistors and ICs, the Silicon that is used as a Conductor in probing can be converted into an Insulator with the help of oxygen and heat supply. In high voltage systems containing transformers and capacitors, liquid insulator oil is the typical method used for preventing arcs. The advantage of this design is that insulator strings with different breakdown voltages, for use with different line voltages, can be constructed by using different numbers of the basic units. In electronic systems, printed circuit boards are made from epoxy plastic and fibreglass. Electrolytes and plasmas contain ions and act as conductors whether or not electron flow is involved. What is Liquid Electricity? The object to be coated with metal is used as a cathode. The Electrical Conductors materials enable the flow of the Electrical current or charges in a single or multiple directions. plastic) coating may be impractical. A thimble helps to prevent direct contact between porcelain and pin. The conductor is suspended at the bottom end of this string while the top end is secured to the cross-arm of the tower. According to the materials, there are Glass insulators, Porcelain insulators, and Polymer insulators. What are the advantages of using insulation? They are designed to reduce the electric field at the point where the insulator is attached to the line, to prevent corona discharge, which results in power losses. We are ranked among the best electrical insulators manufacturers in China. One of the most critical uses of electrolysis is the production of heavy metals like aluminium, sodium, calcium. Testing the electrical conductivity of liquids can be done by the same mechanism. In other words, the Conductors of Electrical materials can be metals, like copper and non-metallic materials, such as graphite as they have free electrons. Some of the polymers used include rubber, epoxy resins, ethylene, Teflon, and ethylene-propylene monomer. However, the conductivity of glass is lower than copper, iron and silver in heated form. In terms of cost, glass insulators are cheaper than porcelain and composite polymer insulators. The electrical function of an insulator is characterized by its resistivity, its dielectric strength (breakdown voltage), and its dielectric constant (relative permittivity). For example, if a liquid or gas contains ions, then the ions can be made to flow as an electric current, and the material is a conductor. Other materialssemiconductors and conductorsconduct electric current more easily. When electric power passes, the water separates into positive hydrogen ions and negatively charged hydroxide ions. Pure liquids are those which are chemically pure and do not contain any other impurity even 9in traces of 1 in 10 , and are structurally simple. However, insulators have a breakdown point where their electrons bend to the will of the current and become conductive. Line post insulators are mounted on the electrical pole for the transmission line. Porcelain is the most preferred material for the overhead transmission lines. For more such information, access free resources available on the Vedantu website useful for the state board, CBSE, ICSE, and competitive examinations. In microelectronic components such as transistors and ICs, the silicon material is normally a conductor because of doping, but it can easily be selectively transformed into a good insulator by the application of heat and oxygen. Film-insulated magnet wire permits a manufacturer to obtain the maximum number of turns within the available space. Overhead conductors for high-voltage electric power transmission are bare, and are insulated by the surrounding air. The liquid that is expected to be the chemical basis for plastics and fuels is as transparent as water and nearly odorless. Intelligence abounds.</p>. Their lightweight also means that they will exert a minimal load on the electric cable. The most important insulation material is air. They are largely used to prevent the flow of Electric current. (The charge level is higher for poorly conductive solvents flowing through plastic tubes. Electrons flow through conductors without damaging the atoms or causing wear. Each unit is constructed of a ceramic or glass disc with a metal cap and pin cemented to opposite sides. They are only suitable for voltage below 50KV. Oxidised silicon is quartz, i.e. Pure water is the best insulator. The ions in this liquid material move freely and conduct heat and electricity. This experiment helps us identify how exactly electricity is conducted through a liquid. Almost every compound, salts dissolve to generate ions which helps to conduct electricity. Usually, household appliances are found to have a heavy plastic coating to perform the duty of an Electrical Insulator. The oil replaces air in spaces that must support significant voltage without electrical breakdown. Insulating material is used as a protective coating on electrical wire and cables. Plastic is used in applications where people or surfaces need protection from electricity or thermal energy. Are you managing a high voltage power transmission project? Porcelain insulator manufacturers also ensure that there are no bubbles and impurities which can affect the insulating property of this material. The insulator in the power system can . Let us begin with the Electrical Insulator definition before discussing the properties of Insulators and the uses of Insulators. A conducting liquid is called electrolyte. These include various mineral oils, silicone oil and many organic liquids. Heres a quick summary of the topic of Electrical Insulators and their examples. Electron transfer from a negatively charged electrode, i.e. ambient temperature). These are the common classes of insulators:[citation needed]. Surprisingly, pure water itself is a poor conductor of water. Image of electrolysis of water displaying split of water in hydrogen and hydroxide ion moving towards cathode and anode respectively to release hydrogen and oxygen gas. Atoms carrying charges are called Ions. You must have observed that the outer covering of your phone charger plug is made from plastic so that the Electric charges do not pass on to human skin. Some of the electrical parameters include dry power frequency and impulse withstand. The phenomena of chemical decomposition of liquid or solution constituting ions when electricity passed through it are called electrolysis. Bulky materials resist conductive and -- to a lesser degree -- convective heat flow in a building cavity. Some liquids such as oil and alcohol do not form ions and do not conduct electricity as well. Porcelain also boasts of a high dielectric strength which can be as high as 60 kV/cm. Excellent chemical stability and gas-absorbing properties. Otherwise, you should consider using a shackle insulator. The electrical properties of an insulator are usually determined by the spacing between the insulating material and the arcing distance. Density: Electrical insulation is used based on volume and net weight. heat: A form of energy that causes substances to rise in temperature or go through associated changes (melting, evaporation or expansion). Insulator (Electricity) Solid. liquid insulator of electricity. 10 Examples of Electrical Conductors and Insulators. As transmission line voltages reached and passed 60,000 volts, the insulators required become very large and heavy, with insulators made for a safety margin of 88,000 volts being about the practical limit for manufacturing and installation. Wire of this type was sold by General Electric under the trade name "Deltabeston."[6]. Thus, Electrical Insulator materials, such as glass, paper, wood, etc. A liquid dielectric is a dielectric material in liquid state. Guy wires supporting antenna masts usually have strain insulators inserted in the cable run, to keep the high voltages on the antenna from short circuiting to ground or creating a shock hazard. Negative charge-carrying ions are called anions. The tightly bound electrons are not free to be shared by neighbouring atoms. However, if the region of air breakdown extends to another conductor at a different voltage it creates a conductive path between them, and a large current flows through the air, creating an electric arc. The water dissociated into hydrogen and oxygen gas when the electric current passed through it. The invention of suspension-type insulators made high-voltage power transmission possible. Petroleum-based mineral oil has become dominant insulating liquid of transformer for more than a century for its excellent dielectric and cooling properties. To make defective units obvious, glass units are designed so that an overvoltage causes a puncture arc through the glass instead of a flashover. Binding wire is used for fixing the conductor in the insulator. Suspension type insulators may be the right insulator for your conductor. This is known as the breakdown voltage of an insulator. Although porcelain was later embraced for high voltage insulators, glass is still used to date. The most common materials include Porcelain, Ceramic, silicon rubber, Polymer, and Glass. One should choose the suitable forms of stay insulators and pole line fittings to prevent the dead-end pole or terminal pole from falling down. Is Glass a Bad Conductor of Electricity? Cookies collect information about your preferences and your devices and are used to make the site work as you expect it to, to understand how you interact with the site, and to show advertisements that are targeted to your interests. Have you got skin with plenty of hair? It is an exceptional electrical insulator. Polymer insulators also feature high tensile strength and are very flexible. Once this voltage is exceeded the material ceases being an insulator, and charge begins to pass through it. In terms of the construction, suspension insulator comprises porcelain discs which are well arranged in series to form a string-like structure. These freed electrons and ions are in turn accelerated and strike other atoms, creating more charge carriers, in a chain reaction. Electrical breakdown occurs when the electric field in the material is strong enough to accelerate free charge carriers (electrons and ions, which are always present at low concentrations) to a high enough velocity to knock electrons from atoms when they strike them, ionizing the atoms. They include; -The voltage head: This is the voltage that is passing through the conductor. The rod is fixed with galvanized steel on both ends. The number of disc units used depends on the voltage. For example: Solution of sulphuric acid ,hydrochloric acid in water conduct electricity. Additional strings can be added when the tension begins to aggravate. Suspension insulators, on the other hand, can be connected into strings as long as required for the line's voltage. In terms of heat, the insulating properties of glass cannot be easily affected by external temperatures. Also known as tension insulators, strain insulators are used when the conductor is subjected to high tension when hanging over particular sections. Helmenstine, Anne Marie, Ph.D. "10 Examples of Electrical Conductors and Insulators." They are applied to-, Coating for Electric poles on the streets. The wires are suspended from a 'string' of identical disc-shaped insulators that attach to each other with metal clevis pin or ball-and-socket links. Cations travel to a negative electrode to collect electrons. Positive charge-carrying ion is called cations. It allows the soundproofing of appliances. The process of conduction of electricity in liquids or electrolysis is extremely useful to the field of electrometallurgy which means the extraction of metals through electricity. The Percus-Yevick theory that is known to produce reliable inter-atomic potential in simple liquid insulators such as argon, as well as the hyperchain theory were used. For example, suspension insulators are usually labelled by their mechanical load capacity (suspension mechanical load). I tried soldering the new length of magnet pickup wires following the epoxy? First, let's talk about what liquid electricity is. Also, if one of the insulator units in the string breaks, it can be replaced without discarding the entire string. WHAT ARE THE DIFFERENT TYPES OF DIELECTRICS USED FOR INSULATION IN ELECTRIC SYSTEM? But normally yes, water it the best liquid conductor. Heavier gases (e.g. In water, the chemical bond of compound breaks into numerous atoms carrying a positive or negative charge on it. Live-front switchboards up to the early part of the 20th century were made of slate or marble. You must be wondering why are Electrical Insulators important for us when Electric charges cannot be passed through it? There are three main types of power line insulators. A perfect insulator does not exist because even insulators contain small numbers of mobile charges (charge carriers) which can carry current. Vinegar contains acetic acid and lemon juice contain citric acid also conduct electricity. This occurs because the "valence" band containing the highest energy electrons is full, and a large energy gap separates this band from the next band above it. This can be seen in rubber-coated wires and cables. The most effective electrical conductors are: Silver Gold Copper Aluminum Mercury Steel Iron Seawater Concrete Mercury Other strong conductors include: Platinum Brass Bronze Graphite Dirty water Lemon juice 10 Electrical Insulators Electric charges do not flow freely through insulators. There is always some voltage (called the breakdown voltage) that gives electrons enough energy to be excited into this band. The resistance to the flow of charges makes it impossible to conduct an electrical current even when the electric field is passed through them. The properties of rubber also cause the electrons to slow down and eventually prevent them from moving at all. A conductor contains large numbers of electric charges that are free to move around (in a metal, these are electrons). Uniform viscosity provides uniform electrical and thermal properties to liquid dielectrics. A large variety of telephone, telegraph and power insulators have been made; some people collect them, both for their historic interest and for the aesthetic quality of many insulator designs and finishes. Stainless steel cutleries in our kitchen like the spoon, fork, etc. She has taught science courses at the high school, college, and graduate levels. This means that there is nothing like best insulators. These positive cations gain an electron from the cathode and convert into stable hydrogen gas. For example, a thick piece of matter will conduct better than a thin piece of the same size and length. Standard suspension disc insulator units are 25 centimetres (9.8in) in diameter and 15cm (6in) long, can support a load of 80120 kilonewtons (18,00027,000lbf), have a dry flashover voltage of about 72kV, and are rated at an operating voltage of 1012kV. Liquid Electrical Tape. It is good at insulating high voltage conductors. The material of the electric insulator is different from others such as conductors and semiconductors, the electric charges do not flow freely when it is passed through the electrical insulator. Nevertheless, Bismuth and tungsten are metals with high resistance value. Large power transformer windings are still mostly insulated with paper, wood, varnish, and mineral oil; although these materials have been used for more than 100 years, they still provide a good balance of economy and adequate performance. Well, irrespective of the source of water, water contains salts, chemicals, minerals which make it impure. Some wires have a mechanical covering with no voltage rating[citation needed]e.g. Some materials such as glass, paper and Teflon, which have high resistivity, are very good electrical insulators.Insulator is any material that prevents the passage of electricity through it. IEC 60797 is one of the standards that are used to address the mechanical properties of an insulator. Herox challengehttps://www.herox.com/cableReferencehttps://ieeexplore.ieee.org/document/172089P.S. Thus insulators are bad conductors of electricity. Class I insulation requires that the metal body and other exposed metal parts of the device be connected to earth via a grounding wire that is earthed at the main service panelbut only needs basic insulation on the conductors. Therefore, uniformity in viscosity is important. [14] However, the flashover voltage of a string is less than the sum of its component discs, because the electric field is not distributed evenly across the string but is strongest at the disc nearest to the conductor, which flashes over first. cathode to hydrogen ion leading to a reduction of the cathode. Production caustic soda from the concentrated saline solution. This page was last edited on 25 October 2022, at 17:06. The most common examples are non-metals. When liquid is passed through thin tubing at a high flowrate, as it is in HPLC systems, the electrostatic charge of the flowing matter generates static electricity (flow electrification). Some insulators like glass are poor conductors when cool but good conductors when hot; most metals are better conductors when cool and less efficient conductors when hot. : service-drop, welding, doorbell, thermostat wire. These materials help to protect any dangerous activity caused by the Electric current flow. The first electrical systems to make use of insulators were telegraph lines; direct attachment of wires to wooden poles was found to give very poor results, especially during damp weather. For this reason, the mechanical properties of the insulator should be on point. Materials that do not permit heat and electricity to pass through it. Dielectric liquids are used as electrical insulators in high voltage applications, e.g. Types of Electrical Insulating Materials Insulating materials can be found in different states like solid, liquid and gaseous. block covering the pickup's connection pins molded into the computer's bar mount AND then Gooping the wire's solder connections Electronic band theory (a branch of physics) dictates that a charge flows if states are available into which electrons can be excited. On the contrary, Electrical Insulator materials do not allow free flow of Electric currents or charges. The liquid-flow analogy is so fitting that the motion of electrons through a conductor is often referred to as a "flow." . If you have two pieces of a material of the same thickness but one is shorter than the other, the shorter one will conduct better because the shorter piece has less resistance, in much the same way that it's easier to force water through a short pipe than a long one. -The distance between the poles. For the dimensions of the guy insulation, static charges on guys have to be considered. Having said that,Aluminum and most other metals like silver, Gold do not conduct electricity quite as good as copper. Otherwise, they are bulky for the voltages above 50KV. What makes a material a conductor or an insulator? Natural contraction and expansion of the wires tied to these "threadless insulators" resulted in insulators unseating from their pins, requiring manual reseating. Liquid dielectrics are commonly applied in transformers, motors, etc. 2010-01-03 07:30:28. . The term insulator is also used more specifically to refer to insulating supports used to attach electric power distribution or transmission lines to utility poles and transmission towers. This construction has the advantage that the ceramic is under compression rather than tension, so it can withstand greater load, and that if the insulator breaks, the cable ends are still linked. It also features a high resistivity to the electricity while at the same time has a low coefficient for thermal expansion. Valence electrons are like outer planets orbiting a star. This type of Electrical Insulator has porcelain discs inside arranged in a series through metal links such that they have a string-like appearance. -High voltage resistance: As expected, the insulators can resist high voltage. When the electric field applied across an insulating substance exceeds in any location the threshold breakdown field for that substance, the insulator suddenly becomes a conductor, causing a large increase in current, an electric arc through the substance. You need to check whether the distance is long or not before you eventually choose the insulator. So even if the outer surface of an Electrical appliance gets wet, the inner surface is dry to keep it leakage resistant. Some of the best Electrical Insulators are rubber, Glass, oil, pure water, wood, Plastic, diamond, dry cotton, and dry air. Therefore, an electrolyte was added to improve the conductivity of pure water. A pin Insulator is best for supporting low voltage line Conductors. Insulators have exceptionally high resistivity. -Provides protection against lightning when used with steel tower. freeze: The process of changing from a liquid to a solid (as ice) by loss of heat. A much larger class of materials, even though they may have lower bulk resistivity, are still good enough to prevent significant current from flowing at normally used voltages, and thus are employed as insulation for electrical wiring and cables. LN2 is about as electrically conductive as air, primarily because. Composite insulators are less costly, lighter in weight, and have excellent hydrophobic capability. This means plastic is an excellent choice of material for some electrical components and systems. If your overhead conductor is conveying high voltage, then you need a better insulator. Electrical conductivity is dependent on electron movement because protons and neutrons don't movethey are bound to other protons and neutrons in atomic nuclei. In physics jargon, we define material with less resistivity as conductors. One of the advantages of polymer insulators is their lightweight. Mathematical descriptions of the electromagnetic field, "Recovery of Alumina Nanocapacitors after High Voltage Breakdown", "Understanding IEC Appliance Insulation Classes: I, II and III", Insulator Usage, A.C. Walker's Insulator Information, "Insulators: National Insulator Association Home Page", Function of Grading rings to Composite Insulator, https://en.wikipedia.org/w/index.php?title=Insulator_(electricity)&oldid=1118188980, Short description is different from Wikidata, All articles that may have off-topic sections, Wikipedia articles that may have off-topic sections from October 2017, Articles with unsourced statements from October 2018, Articles with unsourced statements from May 2012, Articles with unsourced statements from December 2016, Creative Commons Attribution-ShareAlike License 3.0. Simply put, electrical conductors are materials that conduct electricity and insulators are materials that do not. Now, what happens to the charged ions? It is an insulating material that due to its composition is ideal for electrical installations, especially due to its dielectric qualities and ease of use in mechanical actions. One of the main advantages of porcelain material as an insulator is it does not contain any cracks or even holes. Fascinating and Fun Fact with Regards Conduction of Electricity in Liquids, CBSE Previous Year Question Paper for Class 10, CBSE Previous Year Question Paper for Class 12. Materials that do not allow the flow of electricity through it are called insulators. The lower the resistivity, the more readily the material permits the flow . So, which is the right insulator for my power line? Finally, wires that expose voltages higher than 60 V[citation needed] can cause human shock and electrocution hazards. Gases released as the result of this chemical reaction dissipates in the air. An insulating material used in bulk to wrap electrical cables or other equipment is called insulation. The electrical behavior of matter enables us to classify it into two categories: Conductors Insulators All matter is made up of electric charges. [10] To accomplish this the surface is moulded into a series of corrugations or concentric disc shapes. Such insulators can be used either in a horizontal position or in a vertical position. This material can be easily cast into any shape or design. electrical enclosure design; chocolate animal crackers ingredients; Menu. Now, one more thing.. Water (H2O) does not allow the conduction of electricity through it. The only liquid elements which conduct electricity are liquid metals and the only metal liquid at room temperature is Mercury. An insulator contains large numbers of electric charges, but they are not free to move . Its main purpose is to prevent or rapidly quench electric discharges. All internal electrically energized components are totally enclosed within an insulated body that prevents any contact with "live" parts. Vinegar is mostly water with a very small amount of acetic acid in it. These are; -High mechanical strength to support the load, -High electrical resistance to prevent the leakage of current, -The insulating material should be non-porous, -The material should be free of impurities. However, factories using heavy machinery require high-voltage. In coaxial cable the center conductor must be supported precisely in the middle of the hollow shield to prevent EM wave reflections. -If one insulator fails, it can be replaced as the other insulators remain intact, -The arrangement provides flexible operation, -The insulating capacity can be increased by adding more insulators. The important properties of dielectric liquids are therefore electric strength, viscosity, chemical stability and flashpoint. Larger power cables may use compressed inorganic powder, depending on the application. Post insulator - A type of insulator in the 1930s that is more compact than traditional pin-type insulators and which has rapidly replaced many pin-type insulators on lines up to 69kV and in some configurations, can be made for operation at up to 115kV.
