FIELD: electrical engineering.
SUBSTANCE: invention relates to the electrical equipment. Electric winding for dry transformer with winding conductor, which is wound in multiple coils to form coil. Coil is built in a solid insulating case. Coating with definite layer resistance is applied on at least one surface of insulating case. Coating can be made by applying a composition containing water as a solvent and contains a polymer component and at least one microscale and electroconductive filler.
EFFECT: technical result consists in creation of coating with high heat resistance, mechanical strength and resistance to environmental effects.
