Excellent winding performance, mechanical strength, flexible toughness, heat shock and transformer-oil resistanceFor 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.
