INSULATION SYSTEM
VISIBLE BREAK WINDOW
The insulation system consists of the conductor system
embedded in solid dielectric. External insulation is
provided by silicone bushings outside of the powder
coated stainless steel tank. Silicone Rubber Boots fitted
over the bushings provide the necessary clearances
and creepages required for the various ratings.
Surge Arrestors can be mounted on all six (6) bushings
and earthed through the tank. Explosive tail surge
arrestors may be used and there are mounting options
for the surge arrestors both at the top and bottom of
the switch.
The viewing window allows a clear view of the state of
the switch from an operator standing on the ground. The
isolator contact is coated with an iridescent/reflective
paint in the colour red and can be easily seen through
the window even at night with the use of a torch.
The window is designed to remain transparent during
the entire life of the switch, without any discolouration.
It is scratch resistant and can withstand extreme
temperatures and weather conditions such as hailstorms
and sandstorms. IK08 impact ratings are met on all
parts of the switch including the viewing window.
