Insulators are materials that resist the flow of electrical current and are used to separate conductive materials in electrical systems. They are made from a variety of materials, including glass, porcelain, rubber, plastic, and composite materials. Here are some common types of insulators and their descriptions:

- DISTRIBUTION INSULATORS
- TRANSMISSION INSULATORS
- BUS POST INSULATORS
- FUSE DROP-OUT & SURGE ARRESTOR
- INSULATOR FITTINGS
- LT & HT INSULATORS
