Pin type insulator for overhead line
Pin type insulator for overhead line is earliest developed insulator which can be used on power grid up to 33KV system. There exists one part, two parts or three parts about Pin type insulator. It depends upon by application voltage. For example, in 11KV system we generally use one part Pin type insulator for overhead line where whole pin insulator is one piece of properly shaped porcelain or glass.
As the leakage path of insulator is through its surface, it is desirable to increase the vertical length of the insulator surface area for lengthening leakage path. In order to add lengthy leakage path, two, or more sheds are provided on the pin type insulator body. There is another purpose about sheds which are on pin type insulator body. In case of raining, the outer surface of the shed becomes wet but the inner surface remains dry and non-conductive, which is another aim to designing sheds. The sheds will be discontinuations of conducting path through the wet pin insulator surface.
Pin type insulator for overhead line
What is the difference 11KV pin type insulator for overhead high voltage insulator from 33KV pin type insulator for overhead insulator? They have disparate sheds; different creepage distance and power frequency withstand voltage and mechanical failing load.
