Composite insulators have

Composite insulators have

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.

A Pin Insulator

Pin insulator

Pin insulator

A Pin insulator consists of a non-conducting material such as Porcelain, Glass, Plastic, Polymer, or Wood that is formed into a shape that will isolate a wire from a physical support (or “pin”) on a telegraph, utility pole or other structure, provide a means to hold the insulator to the pin, and provide a means to secure the conductor to the insulator. By contrast to a strain insulator, the pin insulator is directly connected to the supporting pole. The earliest pin insulators predate the strain insulator and were deployed before about 1830. Pin insulators continue in production with manufacturers worldwide.
