What is an lectrical insulator?
An electrical insulator is also called a power insulator, it is an essential component in the overhead line and transmission line systems, it is usually mounted on the power towers, poles or other structures to prevent the electric current from flowing to the unwanted regions from the overhead conductors.
The insulator in the power system can also be used on the telephone pole.
The material of the electric insulator is different from others such as conductors and semiconductors, the electric charges do not flow freely when it is passed through the electrical insulator.
