Pin insulators are the first type of overhead insulators developed and are still widely used in power networks up to 33 kV. They can be made in one, two, or three parts based on t… See more

Post insulatorsare similar to Pin insulators, but post insulators are more suitable for higher voltage applications. Post insulatorshave a higher number of petticoats a… See more

In higher voltage, beyond 33KV, it becomes uneconomical to use pin insulator because size, weight of the insulator become more. Handling and replacing bigger size single unit insulat… See more

A suspension string used to handle significant tensile loads is called a strain insulator. It is used where there is a dead end or sharp corner in the transmission line, requiri… See more
