We can supply different type of Hollow & Bushing Insulator, also customer required.Arcing, corona, etc. occur in the device or the end of the hollow core composite sleeve, and the high temperature generated directly acts on the inner wall of the epoxy layer. Or the plasma generated by the arc and the corrosive gas generated by the decomposition of SF6 in the circuit breaker may impinge on the inner wall of the exposed epoxy layer. Polyethylene oxide itself has high temperature ablation resistance, arc resistance and corona resistance, and may cause severe surface ablation and leakage. Therefore, it is necessary to improve the arc resistance of the Hollow & Bushing Insulator. Introduction of Hollow & Bushing Insulator plays an important role in insulation, support, etc. in outdoor power stations, substation and electrical equipment, or as a component of electrical equipment for power equipment. It is usually made of glass fiber hollow-wound tube, upper and lower flanges and silicone rubber shed, which provides support and insulation for wires and electrical equipment, or acts as external insulation for electric equipment, bearing external forces such as bending and stretching.
