Early years of the insulator used for telegraph poles, with the development of technology, and slowly developed in the high-pressure wire to connect one end of the tower hung a lot of disk-shaped insulator, which is to increase the creepage distance, usually made of glass or ceramic , called insulators. Insulator in the overhead transmission line plays two fundamental roles, namely, support wires and prevent current back to the ground, these two roles must be guaranteed, insulators should not be due to environmental conditions and electrical load changes caused by various electrical and mechanical stress and failure, otherwise the insulator does not have a significant effect, it will damage the whole line use and operational life.
Composite insulators is a special insulation control, overhead transmission lines can play an important role.
Composite insulators can be divided into: line composite insulators and power plants, electrical composite insulator. Rod can be divided into composite insulator, composite pin insulator, cross arm composite insulator, pillar of composite insulators, composite insulators and other wind side.
