Every
equipment manufacturer is challenged by
the task of ensuring reliability for an
extended life cycle. Owing to the nature of
the air break disconnector, the equipment
has to withstand harsh environmental
factors. Some such conditions are:
· Extreme operating temperatures
ranging between -50ºC to + 50ºC
· Deposition of ice thickness as high
as 20mm
· Higher Altitudes
· Varying Degrees of Pollution.
· Extreme saline or chemically polluted
environment
· Very high currents – Rated at 4000A
and STCs as high as 63kA
· HVDC Application.
· Different Mounting Positions to
provide flexibility in substation layout
The Air break disconnectors are arranged
either for triple pole, double pole, and single
pole operations or sometimes for tetra polar
operations also.
