Disc Insulators are high tension insulators for transmission and distribution lines from 11kv to 400kv. Glaze adds to mechanical strength and gives smooth surface and ball & socket type discs are the common.

Disc Insulators Salient Features:
Our suspension/tension disc insulators ensure maximum creepage path due to their distinctive geometrical configuration. Smooth rounded contours of shell provide protection against chipping. The glaze applied is compressive in nature, adds to mechanical strength and provides smooth surface for self cleaning under contamination. Caps are made of malleable cast iron and pins of forged steel. These are galvanized to provide better protection against corrosion. Socket caps and pins are checked by specified gauges one and all to assure interchangeability. Socket portion suits 'R' clip or 'W' clip. The security clips are made of phosphor bronze or stainless steel.
