What are the electrical insulation materials

Answer:

Many types of insulating materials, can be divided into gas, liquid, solid three categories. Commonly used gas insulation materials are air, nitrogen, sulfur hexafluoride and so on. Liquid insulation materials are mainly mineral insulating oil, synthetic insulating oil (silicone oil, dodecyl benzene, polyisobutylene, isopropyl biphenyl, diaryl ethane, etc.) two categories. Solid insulation materials can be divided into organic, inorganic two categories. Organic solid insulation materials include insulating varnishes, insulating glue, insulating paper, insulating fiber products, plastic, rubber, lacquered lacquers and insulating impregnated fiber products, electrical thin films, composite products and adhesive tape, electrical laminates and so on. Inorganic solid insulation materials are mainly mica, glass, ceramics and their products. In contrast, solid insulation material variety, but also the most important. Different electrical equipment requirements for the performance of insulating materials are focused. High-voltage electrical equipment such as high-voltage motors, high-voltage cables and other insulation materials require high breakdown strength and low dielectric loss.
Electrical insulation materials are wood, cotton, paper, oily paint, asphalt paint, polyester film, glass cloth, mica, glass fiber, asbestos, composite silicon organic polyester paint, quartz, glass, porcelain material.
Insulation board: plastic plate is made of plastic sheet, plastic for the synthesis of polymer compounds, can be free to change the body style. Plastic is the use of monomer raw materials to synthesis or condensation reaction polymerization of materials, synthetic resin and filler, plasticizers, stabilizers, lubricants, colorants and other additives, and its main component is synthetic resin.
Insulation material is electrical insulation material. According to the national standard GB2900.5 provides the definition of insulating material is: "used to make the device in the electrical insulation of the material." That is, to prevent the current through the material. Its resistivity is very high, usually in the range of 10 ^ 9 ~ 10 ^ 22Ω · m. As in the motor, the insulating material around the conductor isolates the turns and isolates it from the grounded stator core to ensure safe operation of the motor.
