Transpower manufactures full range of Pin Insulator for application in sub-transmission and distribution lines upto a system voltage of 66/72kV. These insulators are available with creepage path to meet various requirements of pollution.
Pin insulators of one piece or multipiece construction are widely used in low cost distribution lines. Multipiece construction makes these insulators less vulnerable to damage. A multipiece insulator can normally withstand the line voltage for a considerable time without difficulty even if one shell is broken
