Abstract
Abstract An electrical insulation coated metallic wire consisting of a releasing layer coated on a metallic wire and an insulating layer superposed on the releasing layer. The insulating layer is formed by coating and baking an insulating varnish on the releasing layer. The electrical insulation coated metallic wire is used as an insulated conductive wire or an insulated resistance wire, the former using an electric conductor as the metallic wire and the latter using an electric-resistive substance as the metallic wire.
