FIELD: chemistry.
SUBSTANCE: invention relates to heat-resistant polymer materials based on organosilicon binder for making electric insulating materials and developing design of winding wires. Composition includes organosilicon resins (A) and (B), poly(dimethyl siloxane) (C), poly(dimethyl methyl hydride siloxane) (D), and platinum catalyst (E). Design of winding wire contains conductor thread coated with two-layer, thermally treated insulation, first layer therein is made from mica-containing tape consisting of electrically insulating glass fabric and mica paper, impregnated and glued together with said composition, and second layer therein is made of polyimide fluoroplastic film.
EFFECT: technical result of invention is producing electric insulating materials with high flexibility and fire-resistance, and also higher corona-proofness and flexibility of wire insulation.
