Porcelain pin type insulator consists of a single piece of ceramic or two more ceramic components permanently connected together and intended to mounted rigidly on a supporting structure by an insulator pin/spindle. Unless otherwise stated, this term does not include the insulator pin. Normally, porcelain pin type insulators are used on upon 69kv distribution lines. Pin type insulator can be Zinc thimble with thread type and porcelain thread type.
The types of porcelain pin type insulator are 55-1/2/3/4, 56-1/2/3/4, P-11/15/22/33-Y, PW-15/22/33-Y.
