P-11-Y Brown Glazed Pin Insulator High Voltage Porcelain Insulators


An electrical insulator (also referred to as an insulator) is used in an electrical system to prevent unwanted flow of current to the earth from its supporting points. The insulator plays a vital role in the electrical system. An electrical insulator is a very high resistive path through which practically no current can flow.

In transmission and distribution systems, the overhead conductors are generally supported by supporting towers or poles. The towers and poles both are properly grounded. So there must be an insulator between tower or pole body and current-carrying conductors to prevent the flow of current from conductor to earth through the grounded supporting towers or poles.

Porcelain is the most commonly used material for overhead insulators in the present day. The porcelain is aluminum silicate. The aluminum silicate is mixed with plastic kaolin, feldspar, and quartz to obtain final hard and glazed porcelain insulator material.
