The composite insulator is mainly composed of glass fiber epoxy resin pull-out rod, silicone rubber umbrella skirt and hardware. The silicone rubber umbrella skirt adopts the integral pressure injection process, and then deals with the key problem of interface breakdown affecting the reliability of composite insulators. The combination of glass pulling rod and fittings adopts more advanced crimping technology, and is equipped with automatic acoustic flaw detection system, which has the characteristics of high strength, beautiful appearance and small volume.
In the early years, insulators were mostly used in electric poles. With the development of science and technology, they gradually developed in high-voltage power lines. Many disc-shaped insulators were hung at one end of the connecting tower. It is to add creepage spacing. It is generally made of glass or ceramics, which is called insulators. Insulator plays two basic effects in overhead transmission line, that is, supporting conductor and avoiding current return to ground.
These two effects need to be ensured. The insulator should not fail due to various electromechanical stresses caused by changes in environmental and electrical load conditions, otherwise the insulator will not produce significant effects, which will damage the service and operation life of the whole line. Composite insulators can be divided into: line composite insulators and power station and electrical composite insulators.
