Composite 11kv pin insulator

Composite 11kV Pin insulator is the earliest developed overhead insulator, but still popularly used in power network and distribution lines made of silicone rubber.

Pin type insulator can be of a one-part, two-part or three part type, depending upon the application voltage. In 11KV system, we generally use one-part type insulator where the whole pin insulator is one piece of properly shaped porcelain or glass. But composite pin insulator is popular used replacing porcelain or glass insulators.

As the leakage path of the insulator is through its surface, it is desirable to increase the vertical length of the insulator surface area for lengthening the leakage path.

In order to obtain lengthy leakage path, one, two, or more rain sheds or petticoats are provided on the insulator body. We can manufacture big shed for pin insulator to increase creepage distance.

We also produce 900mm creepage distance pin insulators, if you want to buy 11kV pin insulator or other insulators, please email to Orient Power.
