What is Insulator & Usage in India?

An electrical insulator is a material in which electric current does not flow freely. The atoms of the insulator have tightly bound electrons which cannot readily move.

Insulators are widely used in overhead transmission lines to provide mechanical support and electrical protection, as well as in distribution lines and substations. In transmission and distribution (T&D) systems, overhead conductors are usually supported by towers and poles, which are both grounded.

Usage of Insulator in India

Depending on voltage considerations, different kinds of insulators are used in power systems. A look at some types of insulators and the conditions under which they are deployed.
