Abstract

The invention discloses a novel wire insulating material and relates to the technical field of electric engineering. The insulating material contains, by weight, 40-50 parts of nano-ceramics, 10-19 parts of polyurethane, 20-40 parts of chlorinated polyethylene rubber, 15-22 parts of silicon carbide, 2-8 parts of barium sulfate powder, 1.8-4.2 parts of sodium silicate, 2-5 parts of rubber, 8-11 parts of xylenol, 2-6 parts of iron oxide powder, 1.5-1.9 parts of sulphur, 9-17 parts of oxalic polyester, 12-16 parts of diglycidyl cyclohexanedicarboxylate, 4-12 parts of meerschaum, 2-7 parts of asphalt, 4-8 parts of an adhesive and 6-10 parts of a plasticizer. According to the novel wire insulating material, nano-ceramics is used as the main raw materials, and the other raw materials function together and cooperate with each other. Thus, the insulating material has good insulating properties, high strength, high temperature resistance, low high-frequecny loss, good humidity resistance, excellent flame retardancy and ageing resistance and long service life, and is appropriate to be used as a wire.

Description

technical field [0001] The invention relates to the technical field of electrical engineering, in particular to a novel wire insulation material. Background technique [0002] According to the national standard GB2900.5, the definition of insulating material is: "the material used to make the device electrically insulated". That is, a material that prevents the passage of electric current. Its resistivity is very high, usually in the range of 10^9 to 10^22Ω m. As in an electric motor, the insulation around the conductors isolates the turns from each other and from the grounded stator core to ensure safe operation of the motor. [0003] At present, the power industry is in a period of rapid development, and electrical products have been popularized in various industries. The insulation requirements of electrical products are very high. Although there are many types of surface insulation materials on the market, the performance is relatively single, and their uses are highl...
