Insulator is a special insulating control which can play an important role in overhead transmission line.In the early years, insulators were mostly used in power poles, which gradually developed into a kind of dish-shaped insulator hanging at one end of the high-type high-voltage wire connecting tower. It is to increase the creepage distance and is usually made of glass or ceramics, which is called insulator.
