What Is A Post Insulator?

Pillar high voltage standoff insulators is a special insulating control component that can play an important role in overhead transmission lines. In the early years, pillars high voltage epoxy were mostly used for electric poles, and gradually developed into high-type high-voltage electric wire connection towers with many suspended insulators hung on one end. It is to increase the creepage distance. It is usually made of silicone or ceramic, which is called epoxy resin insulator.high voltage epoxy resin plays two basic roles in overhead transmission lines, namely supporting the conductors and preventing the current from returning to the ground. These two roles must be guaranteed. high voltage standoff should not fail due to flashover breakdown caused by changes in environmental and electrical load conditions, otherwise the insulator will lose its function and damage the use and operation life of the entire line.
