What Are Insulators Used For?

The main function of Insulator is to provide electrical insulation and mechanical support.

Electrical insulation:

Insulators are used in power systems to electrically isolate conductors of different potentials and between conductors and ground potential components to prevent current leakage and short circuit accidents. It effectively blocks the electrical connection between electrical equipment through the characteristics of high resistivity and low conductivity, ensuring the safety and stability of power transmission.

Mechanical support:

Insulators also play an important role in mechanical support. In high-voltage transmission lines, conductors need to cross complex terrain. Insulators provide stable support points that can withstand external forces such as the weight of the conductors, wind and temperature changes, ensuring the normal operation of the conductors and the stability of power transmission.

In addition, insulators also have a certain environmental protection function, which can resist the erosion of severe weather conditions such as lightning, dirt, ice and snow, and protect power facilities from damage.
