Insulated Coating Resistance Wire

Introduction
Insulated coating resistance wire is a kind of wire with insulation layer, formed by painting one or several insulating paints on the conductor surface and then being baked and cooled. This resistance wire is widely used in standard resistor, automobile parts, winding resistor, insulation treatment, etc., and commercial production, home appliances and other industries. In addition, we can also conduct enameled coating insulation on precious metal wires like silver and platinum wire.
