Product Description

15kv Pin Type Porcelain Insulator for Overhead Line

Insulators are a special insulation control that can play an important role in overhead transmission lines. In the early years, insulators were mostly used for telegraph poles. Slowly, a lot of disk-shaped insulators were hung on one end of the high-voltage wire connection tower. It was used to increase the creepage distance. It was usually made of glass or ceramics and was called an insulator. Insulators should not fail due to various electromechanical stresses caused by changes in the environment and electrical load conditions, otherwise the insulators will not have a significant effect and will damage the use and operating life of the entire line.
