Epoxy Resin Glass Filament Winding Tube

FRP electrical insulaiton Filament Winding  tubes Product Descripton:

360 Epoxy glass fiber winding tube   EPCF52(IEC)

Glass fiber yarn immersed in epoxy resin and other different proportions of insulating gluethroughwet process rolling and then heating and curing. This product has high temperature resistance H-class,with good electrical properties and mechanical Performance, low dielectric loss, non-deforming layered, chemical resistance (SF6) and other characteristics.

Widely used in H-class dry-type transformers, on-load tap switch, reactors, arresters, SF6 mutual inductor and other products for the main insulator.
