GANG
OPERATED AIR BREAK ISOLATING SWITCH [11 kv HEAVY]
Application 
This
product has been designed to suit overhead systems used in
high density urban situations or high load centers, where
the load current is much higher and the need of improved
quality supply is much greater. Main function of this
product is to isolate the transformer from distribution
system and also used for system isolation from distribution
network.

DISCONNECTOR
LINK
Application
Disc
connector link is a type of isolator switch but is
individual phase operated switch. Its operation is achieved
by insulated operating rod. Disc connector link has been
designed to suit in combined overhead underground
network. It is installed at point of tapping from overhead
line to underground cable. High standard performance and
easy fault location are combined with low installation cost
and safety from mischievous operation makes the disc
connector link best suitable for overhead network used in
high-density urban situation.
