Problems solved by technology

[0002] At present, the ceramic film-covered wire products on the domestic and foreign markets, among them, the high-temperature resistance and corona resistance of the common ceramic film-covered wire products in the domestic market are poor, and the most excellent domestic ceramic film-covered wire products have better high-temperature resistance ( 220 ℃), but the corona resistance is still poor. The most excellent foreign ceramic film-covered wire products have good corona resistance (about 100 hours), but the high temperature resistance is still poor. Therefore, there is an urgent need for a simultaneous Ceramic film-covered wire products with high temperature resistance and corona resistance
