Abstract
PURPOSE: To prevent an insulating layer from exfoliating from the electric conductor, by interposing a heat-proof insulating base material of modulus of rigidity, smaller than that of the heat-proof varnish of the insulating layer, between the electric concuctor and the insulating layer.
CONSTITUTION: On an electric conductor 1, are wound a collective mica tape and polyamides film as a heat-proof insulating base material 2, and, for instance, epoxy resins are impregnated as a heat-proof varnish 3, being hardened with an insulating layer 4 constructed. And between said insulating layer 4 and the electric conductor 1, is interposed a film of ethylene tetrafluoride and the like as a heat-proof insulating base material 5. Said heat-proof insulating base material 5 is selected so as to provide a modulus of rigidity smaller than that of the heat-proof varnish 3. In this way, even at a high temperature above F-class, with an exfoliation not generated in the surface boundary between the electric conductor 1 and the insulating layer 4, the reliability can be enhanced.
