Corona-resistant polyimide film not only has the characteristics of high and low temperature resistance, electrical insulation, radiation resistance and corrosion resistance of common polyimide film, but also has super corona resistance and good thermal conductivity. It is suitable for turn-to-turn insulation and main insulation of large traction motors, variable frequency motors, wind power generation motors, special motors, etc., and corona-resistant protective layer of extra-large coil external insulation, etc.
