Epoxy Glass Fiber Winding Tube 360 EPCF52
Description:
This product adopts fiber glass yarn that is impregnated with insulation jelly made of epoxy resin and other resins by certain proportion, and then it is rolled in wet method, and dried and finally consolidated by baking. Its heat resistance level is up to Class H, and it also has excellent electrical and mechanical properties, chemical resistance (SF6), low dielectrical loss, no deformation or delamination. It can be used as main insulator on H grade dry-type transformer, load tap changer, electric reactor, lightning arrestor, SF6 inductor, etc.
