Abstract
PURPOSE: To provide an insulated winding of high initial dielectric strength and good heat-resisting property, by winding a combined heat-resisting material integrated by a polyimide resin, impregnating the material with an epoxy-isocyanate resin of a prescribed equivalent ratio, and setting the latter resin.
CONSTITUTION: Different kinds of heat-resisting materials such as an organic heat- resisting film and an inorganic porous material are integrated with each other by a polyimide resin to prepare a combined heat-resisting material. This combined material is wound around a conductor and then impregnated with an insulating varnish which is prepared by mixing 1.0 equivalent of a polyfunctional epoxy compound with 1.5∼25.0 equivalents of a polyfunctional isocyanate compound. The insulating varnish is set. This results in providing a heat-resisting electric winding which excels in initial dielectric strength and heat-resisting property and can be applied to the class C insulation.
