FIELD: electrical engineering.
SUBSTANCE: electric winding for dry transformer has multiple wound coils of winding conductor to form a coil. Coil is built into the solid insulating case, which is part of the winding. On at least one surface of the insulating body there is a coating made by applying a composition containing water as a solvent. Coating includes a polymer component and at least one nanoscale and electroconductive filler.
EFFECT: technical result consists in improvement of heat resistance, mechanical strength and resistance to environmental effects.
