Product Description

Composite Station Post Insulators

Product Description

In the early years, station post insulators were mostly used for telegraph poles. With the development of science and technology, a lot of disc-shaped insulators were hung at one end of the high-type high-voltage line connection tower, which was to increase the creepage distance.Insulators play two basic roles in overhead transmission lines, that is supporting conductors and preventing current from returning to the ground. These two roles must be guaranteed. Insulators should not fail due to various electromechanical stresses caused by changes in the environment and electrical load conditions, which will damage the operating life of the whole line.
