Nikum make
Center rotating type triple Pole outdoor on load
disconnecting switches for higher line current
breaking capacity for line Isolators. The isolators
are having a fixed and moving contacts made of HDHC.
Copper and die forged fingers of phosphorus bronze
having inherent non deteriorating spring qualityat
high temperature and corrosion proof.
The assembly of fixed and moving contains is based
on self compensating princile, to withstand both
thermal and dynamic stresses of short circuit
current and still carry the continuous rated current
with plenty of margin under the maximum specified
temperature. All ferrous parts are hot dipped
galvanized and non ferrous parts are heavily tin
platted to provide protection against corrosion,
contacts for higher current rating are silver
platted.
Earth switch can be easily installed on each pole at
either end and interlocked mechanically with the
main switch. the auxiliary switches can be provided
for man as well as for earth switch. Electrical
interlock can be provided, Electrical moter drive
mechanism complete with reduction gear and torque
limiting safety features can also be provided.
Isolators are manufacturers in normal and solid core
post insulators range covering from 6.6KV to 220KV.
