Abstract

A partial-discharge-resistant insulating varnish has a polyamide-imide enamel varnish and an organo-silica sol that are dispersed in a solvent. The solvent has 50 to 100% by weight of γ-butyrolactone. An insulated wire has a conductor, and a partial-discharge-resistant insulation coating film formed on the surface of the conductor. The partial-discharge-resistant insulation coating film is made of the partial-discharge-resistant insulating varnish.
