11kV Porcelain Ceramic Substation Post Insulator High Voltage

Product Description

11kV High Quanlity Porcelain Ceramic Substation Post Insulator

 

Quick Detail: 

An 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.
