Introduction of insulator

In the early years, insulators were mostly used for telephone poles. With the development of science and technology, they were slowly developed at the end of high-type high-voltage wire connection towers. A lot of disk-shaped insulators were hung at the end of it. , Called an insulator. Insulators play two basic roles in overhead transmission lines, namely supporting wires and preventing current from returning to ground. These two roles must be ensured. 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, and it will damage the use and operating life of the entire line.

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 composite insulators for power stations and electrical appliances. It can also be divided into rod-shaped suspension composite insulators, pin composite insulators, cross-arm composite insulators, pillar composite insulators, wind-proof bias composite insulators, etc.
