Problems solved by technology

[0002] Power transmission is achieved by using a transformer to boost the power generated by the generator, and then connecting it to the transmission line through circuit breakers and other control equipment. According to the structure, the transmission line is divided into overhead transmission lines and cable lines. Conductors, insulators, line fittings, guy wires, tower foundations, grounding devices, etc. are erected on the ground. According to the nature of the transmission current, power transmission is divided into AC transmission and DC transmission. In this process, the surface of the insulator is coated with anti-pollution flashover Coating is currently the most effective anti-fouling flashover measure, but with the aggravation of air pollution and the increase of smog, the anti-fouling flashover coatings currently used are poor in water resistance and have unsatisfactory mechanical properties
