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.
