PROBLEM TO BE SOLVED: To provide a highly reliable high heat-resistant winding with higher heat resistance than a polyimide enamel wire, high flexibility, high electric insulation, and high corona resistance. SOLUTION: This highly heat-resistant winding is manufactured by forming an inorganic fine particle dispersion polyimide enamel film layer on a conductor, and installing a heat resistant impregnation paint impregnation heat resistant fiber material layer on the inorganic fine particle dispersion polyimide enamel film layer. |
