Epoxy fiberglass winding tube
Product Parameters：
Color: Green
Wall thickness: ≥0.8mm
Length: 1000mm
Heat resistance rating: Class H
Support customized
This product is made of fiber glass yarn impregnated with insulation glue, epoxy resin and other resins by certain proportion, and then it is rolled in wet method, 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 is widely used as main insulator in dry- type transformers, load tap changers, electric reactors, lightning arrestors, SF6 inductors, etc.
