Description

technical field [0001] The invention relates to the technical field of electric insulation materials, in particular to a high temperature and anti-aging electric insulation material and a manufacturing method thereof. 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 1~10Ω.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. At present, the application range of electrical insulation materials is getting wider and wider, and the requirements for their performance are getting higher and higher. Insulation performance is only the basic performance it should have, and its anti-aging is particularly important. El...
