ABSTRACT:
Improved method for producing an electrically insulated conductive body such as coils, etc. for use in electrical apparatuses and appliances, wherein an electrically conductive body is immersed in an electrodeposition paint liquid prepared by dispersing into water mica powder as an inorganic insulative substance and water-dispersion varnish as an organic insulative substance, thereby forming an electro-deposited layer on the electrically conductive body by electrophoresis, followed by drying the electro-deposited layer coated on the electrically conductive body under heat, then the dried electro-deposited conductive body is immersed in a water-soluble resin solution containing therein a curing agent, followed by drying the resin coating under heat, and finally the resin-coated, electro-deposited conductive body is impregnated with an impregnating resin, followed by heat-setting the resin as impregnated.
