FIELD: chemistry.
SUBSTANCE: insulating compound is proposed, mainly for the manufacture of components for the cable industry, which contains: 70-100 parts by volume of a polymer material, 5-30 parts by volume of a ceramic filler (2), the surface of which is treated with a bifunctional coupling agent in an amount of 0.1 wt % to 4 wt %, based on the ceramic filler, 0.1 to 5 parts by volume of the crosslinking agent, 0 to 6 parts by volume of the conductive carbon powder (3); And 0-6 bulk fractions of whiskers (4) ZnO. The method of manufacturing an insulating composition comprises surface treatment of a ceramic filler with a bifunctional coupling agent, followed by its mixing with a polymeric material and a crosslinking agent in the presence of ZnO.
EFFECT: improvement of dielectric strength, heat resistance, durability and reliability of cable products manufactured from material declared insulation composition.
