Insulators: Materials that do not allow electricity to pass through them are called insulators. Example: Rubber, glass, plastic, etc
Types of insulators:
There are mainly five types of insulators, such as:
Suspension insulators - An insulator that acts as a conductor to protect an overhead transmission cable is called a suspension insulator.
Strain insulators - String insulators are utilized whenever a suspension string is needed to support a high tensile pressure on some kind of conductor.
Pin insulators - The first ceiling-mounted insulators to be created, and they've been widely employed in power networks up to is called pin insulators.
Stay insulators - A type of low voltage insulator used to balance and secure the dead-end pole using stay wire or guy grip is called stay insulators.
Shackle insulators - An insulator that is utilized in low voltage distribution networks is called a shackle insulator.
