compositehigh-voltage

The development of composite insulator industry With the development of the ultra-high voltage AC and DC of power grid, the composite insulator, with its unique characteristic, is widely used in the power grid. Compared with the traditional porcelain insulator, composite insulator has the advantage of excellent seismic and wet dirt resistance, high strength, light weight, easy operation and maintenance, invulnerability to breakage and its umbrella skirt an d shed can be repaired. Especially in the field of ultra-high voltage, the cost performance of composite insulator is particularly prominent. Since the beginning of 1998, Pinggao has been engaged in the development of composite insulator, now has the mature development technology of 12 kV ~ 1100 kV ac and dc hollow, pillar composite insulator and the whole series of ac and dc voltage grade line insulator products. The main products are hollow composite insulator, pillar composite insulator, composite insulator for arcing chamber, optical fiber composite insulator, composite sleeve, wall bushing, can meet the requirements of the AC/DC power station of each voltage grade. At present, more than 60000 composite insulator which were developed by Pinggao are operating safely in various area at home and abroad. 110kV～1100 kV hollow composite insulator 1. The structure of hollow composite insulator Hollow composite insulator as a main component of composite bushing, play a role of the casing mechanical load, the electrical insulation.Hollow composite insulator is composed of silicon rubber umbrella cover, glass fiber winding tubes, end metal flange.
