What's the use of composite insulator in transmission line?

by:Mings     2020-07-11

composite insulator was tormented insulator for pole, with the development of science and technology, gradually develop from one end of the high type high voltage wires to hang a lot of disc insulators, in order to increase the creepage distance, it is usually made of glass or ceramic call insulator.

composite insulator in overhead transmission lines with two basic role, composite insulator supporting wires and to prevent the current back to the ground.

worth noting that these two functions must be guaranteed, the insulator should not change due to environmental and electrical load conditions lead to a variety of electrical and mechanical stress and failure, or else there won't have a significant role in the insulator, will damage the whole line of use and operating life.
