Insulators are a special kind of insulation control that can withstand voltage and mechanical stress in overhead transmission lines, enabling effective insulation between different potential conductors or between conductors and ground potential components. Insulators are widely used in the power sector. Transmission lines, power plants, substation busbars, and external live conductors of various electrical equipment must be supported and connected by insulators. The insulator is generally made of an insulating member (such as a porcelain piece, a glass piece, etc.) and a metal accessory (such as a steel leg, an iron cap, etc.) by glue or mechanically.
