FIELD: chemistry.
SUBSTANCE: coating material (20) for electrical equipment comprises: an epoxy resin matrix (50), the first filler (10) contained dispersed in a resin of the matrix (50) and consisting of ZnO whiskers with a semiconductor bulk resistivity, the second filler (30) made of Fe2O3 or Fe3O4 contained dispersed in a resin of the matrix (50) and consisting of particles with a semiconductor bulk resistivity, and the third filler (40) contained dispersed in a resin of the matrix (50) and consisting of a layered substance (talc, boron nitride), a fibrous substance (from whiskers of potassium titanate or ground glass fibers), or lamellar material (mica or smectite).
EFFECT: improved material properties.
