-Insulator is a special insulation control that plays an important role in overhead transmission lines. In the early years, insulators were mostly used on telephone poles. Later, many disc-shaped insulators were hung on one end of high-voltage wire connection towers to increase the creepage distance. They were usually made of glass or ceramics and were called insulators. Insulators should not fail due to various electromechanical stresses caused by changes in environmental and electrical load conditions, otherwise the insulators will not play a significant role and will damage the use and operating life of the entire line.
