Insulators are widely used in power systems. They are generally external insulation and work under atmospheric conditions. The busbars of overhead transmission lines, power plants and substations, and external live conductors of various electrical equipment must be supported by insulators and insulated from the earth (or grounding objects) or other conductors with potential differences. Among them, the iron cap is a metal accessory connected to the suspension insulator and is one of the main components of the suspension insulator.

The limiting rod 8 can be conveniently flipped through the rotating shaft 13 and the connecting piece 14; the fixed end piece 11 and the limiting rod 8 are integrally formed, and the clamping block 15 is fixedly installed on the fixed end piece 11.
