Electrical Insulator Royalty-Free Stock Photo

Mains insulators have the function of isolating an electrically conductive material from any other material. They are used in distribution networks with covered or bare wires of class 13.8kv and 34.5kv. The mains insulators have a threaded hole and are mounted on steel pins. Inside its threaded hole, it contains a heating paste that is between the pin head and the insulator. This mass serves to prevent the formation of discharges or even the erosion of the electrical network insulators.
