Polyurethane enameled copper wire for sealed coils is insulated with smooth surface non-cresylic polyurethane. Emission of gases which are harmful to electrical contacts is kept to a minimun. Features The life of sealed relays contact is extended by minimizing the amount of organic gas emitted. With its outstanding uniform surface smoothness, the wire is suitable for high-speed coil winding. Applicable standards : JIS C 3202 "Polyurethane enameled round copper winding wires" Applications : Sealed coils of small size, relay coils.
