Epoxy Resin Fiber Glass Insulation Winding Tube

















description:
Glass fiber yarn immersed in epoxy resin and other different proportions of insulating glue, through wet 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.
