Fiberglass Reinforced Epoxy Resin Wound Pipe

Send Message Request a Quote

Our fiberglass reinforced epoxy resin wound pipe is commonly used in the manufacturing of electrical equipment structural components like fuse protector, on-load tap changer, transformer, lightning arrestor, electric reactor, and 110KV~ 1000KV composite hollow insulator, just to name a few. Its performance meets the IEC standards. This twining tube is made from non-alkali glass fibers as well as epoxy resin using a cross-winding method. In addition, we can offer products with a complete range of specifications to suit individual clients' needs.
