post insulators

post insulators are a special kind of insulation control that can play an important role in overhead transmission lines. In the early years, the pillar insulators were used for the poles and slowly developed at the end of the high-voltage high-voltage wire connecting tower. Many of the suspended insulators were mounted in order to increase the creepage distance, usually made of silicone or ceramic. Insulators in the overhead transmission line plays two basic roles, that is, to support the wire and to prevent the current back to the ground, these two roles must be guaranteed, the insulator should not be due to changes in environmental and electrical load conditions caused by a variety of mechanical and electrical stress failure, Otherwise the insulator will not have a significant effect, it will damage the use of the entire line and operating life.
