Background

Insulators are devices mounted between conductors of different potential or between a conductor and a ground potential member, capable of withstanding voltage and mechanical stress. The insulating control is a special insulating control and can play an important role in overhead transmission lines. The insulator is mainly used for telegraph poles in early years, and a plurality of disc-shaped insulators are hung at one end of a high-voltage wire connecting tower, so that the creepage distance is increased, and the insulator is usually made of glass or ceramic. The insulator should not fail due to various electromechanical stresses caused by changes in environmental and electrical load conditions, otherwise the insulator will not have a significant effect, which would impair the service and operational life of the entire line.

According to statistics, most of the initial arc positions at the insulator are at the insulator core rod, the umbrella skirt is less, the umbrella skirt is complex in structure and generally unfavorable for the generation and development of electric arcs, and therefore, the interactive electrode structure porcelain body is proposed.
