Product Details


Hollow Composite Insulator is mainly composed of epoxy fiberglass reinforced twine pipe, silicone-rubber adds sheds increasing creepage distance and connecting flange. Epoxy fiberglass reinforced twine pipe, which is the insulating inner part of composite hollow insulator, is processed by special winding machine using epoxy resin impregnated fiberglass according to mechanical laydown design, and has excellent mechanical strength and dielectric property. As the external insulation of composite hollow insulator, silicone rubber add sheds increasing creepage distance takes on necessary electric functions, such as protecting and providing creepage distance. Connecting flange, which is made of aluminum through compression casting, adopts unique adhesive technology to deliver mechanical load and provide sealing for supporting and connecting structures. Composite Hollow Insulator is suitable for 40.5KV-550KV power system. For example, high voltage electric products like SF6 transformer, SF6 line breaker bushing, arrester, high voltage bushing, subsection capacitor, cable terminal, etc.
