Abstract

PURPOSE:To contrive not to hinder impregnation with the prevention of the out- flow of impregnated resin, by providing a porous film material on the outer layer of an insulating layer. CONSTITUTION:The stator coil formed in a hexagonal shape by the required turns of an insulating conductor 1 is wound up with the insulating layer 3 constituted of e.g. mica tape, glass tape. Next, the outer boundary of the insulating layer 3 is provided with an out-flow preventing layer 4 constituted of microporous film material. The porous film material is constituted of polyethylene resin with thickness approx. 150mu, average hole diameter lmu or less and with distribution 0.01-10mu and 65% in porosity. Next, insulating resin is impregnated further with heating-hardening to obtain the insulating wiring for electric apparatus.
