FIELD: electricity.
SUBSTANCE: electrical machine containing winding (34) made of electric insulating material. Electrical machine also includes insulating layer (38) arranged around at least a part of winding (34) which dielectric constant changes depending on voltage. Nano filler is added to insulating layer.
EFFECT: increasing dielectric constant of insulating layer and improving adaptation of insulation system to fluctuations of electric load.
