High Voltage Overhead Power Pole Ceramic Post Insulator 57 Series 11kV 15kV 22kV Suspension Insulator for Transmission Line

Insulator is a material or method that restricts the transfer of either heat or electricity. In the case of heat, thermal insulators work by reducing the rate heat can travel through a space. Generally, they use specific materials and will keep heat-carrying matter from moving. In the case of electricity, electrical insulators confine an electric current to a designated path. They typically work by using a material with many outer elections, a condition that will cause low electrical conductivity.
