enamelled copper wire
Product Detailed
there are different types of insulated paper to wrap one or more naked conductor or varnished conductor.
Product introduction: Enameled wire is the insulated conductor with most applicated scope.
Huadian adopts the most advanced equipments and processes to fullfil the fully digital
production process of enameled wire.The controlling accurate of temperature till to 1°C,
over 12 pieces of painting processes and micrometer painting models can make sure the
enamled wire be nice and average characteristics.

characteristics and usage | For oil-immersed transformer windings. Excellent winding performance, mechanical strength, flexible toughness, heat shock and transformer-oil resistance | For Grade 180 electrical winding. Flat wire boasts unique roll-resistance and good adhesion because of special resin primer. | Best choice for Grade 200 electrical winding. For dry electrical motor, dry transformer and nuclear power system. Outstanding roll-resistance and aging resistance in the transformer oil | High mechanical strength, excellent heat, chemical and refrigerant resistance. Widely used in the automobile industry, windings in electrical motor and apparatuses under extremely cold, radiation and over-load operation conditions | For excess heat applications. Good electricity and chemical resistance. Especially used in the war industry, nuclear industry and outer space field. | For power transformer winding requiring for self-adhesion during the thermal treatment. Excellent transformer-oil resistance | |
