<P>PROBLEM TO BE SOLVED: To provide an insulating varnish capable of forming an insulating film satisfying both scratch resistance and suppression effect of partial discharge deterioration furthermore than hitherto, while having an insulating film thickness equivalent to hitherto, and to provide an insulated wire using the insulating varnish. <P>SOLUTION: This insulating varnish, which is an insulating varnish for forming an insulating film, is based on a resin coating formed by dissolving a resin comprising one kind selected from a polyamideimide resin, a polyesterimide resin and a polyimide resin into a solvent containing γ-butyrolactone as a main component, and in the resin coating, organosol in which an inorganic material is dispersed into a dispersion medium containing cyclic ketones as a main component, and a lubricant are further added and mixed. Concerning this insulated wire, an insulating film by the insulating varnish is formed on the outer periphery of a conductor, and the insulating film configures the outermost layer. <P>COPYRIGHT: (C)2013,JPO&INPIT |
