Zusammenfassung:Partial discharge resistant insulating lacquer comprises: a polyamide-imide-enamel lacquer and an organo-silica-sol that is dispersed in a solvent comprising 50-100 wt.% of gamma -butyrolactone. Independent claims are included for: (1) an insulated wire comprising a conductor, and a partial discharge resistant insulating cover film, which is formed on the surface of the conductor, where the partial discharge resistant insulating cover film is made of partial discharge resistant insulating lacquer; (2) the preparation of partial discharge resistant insulating lacquer; and (3) the preparation of the insulated wire comprising: preparing the partial discharge resistant insulating lacquer and coating the partial discharge resistant insulating lacquer on the surface of a conductor and then burning of the lacquer in order to form a cover film on the conductor.
