What Is The Composite Insulator?

Dec 12, 2018

Composite insulators are a special type of insulation control that can play an important role in overhead transmission lines.

Composite insulators can be divided into: line composite insulators and power stations, electrical composite insulators. Can also be divided into rod-shaped suspension composite insulators, needle composite insulators, cross-arm composite insulators, pillar composite insulators, wind-proof partial composite insulators.

In the early years, insulators were mostly used in utility poles. Following the development of technology, many disc-shaped insulators were hung on one end of the high-voltage high-voltage wire connecting tower. It was added to climb the electric insulation interval, usually made of glass or ceramic. It is called an insulator. Insulators play two fundamental effects in overhead transmission lines, namely supporting the conductors and preventing current from returning to the ground. These two effects are necessary to ensure that the insulators should not fail due to various electromechanical stresses caused by changes in environmental and electrical load conditions. Otherwise, the insulator will not have a significant effect, which will jeopardize the operation and operation life of the entire line.
