Introduction:
Polyester-imide film series has excellence dielectric strength , heat resistance , radiation resistance and insulation properties , film wrapping wires often use to replace enamel wire to cost saving and also use for modern high-tech industries.
Glass fiber wires have two types insulation.
Varnish + Glass Fiber + Varnish , normally the insulation thickness is 0.3 mm and outer layer wrapped by Polyester-imide film , often use for motors.
Varnish + Glass Fiber + Varnish + Glass Fiber + Varnish , normally the insulation thickness is 0.4 mm , without film cover outside , often use for transformer.
Thermal Class: 180 degree or others as customer’s requirement
Standard: IEC 60317
