Functional design
1. Reliable
Each compartment is monitored individually & has its own
pressure relief device.
2. Safety
The primary side components are hermetically enclosed, gas filled
compartment and thus insensitive
to atmosphere, dirt &dust.
3. Space saving
Smaller foot prints All operations on the switchgear front.
4. Economically efficient
Reduced space & surface area requirement. Long service life
Maintenance free Gas compartment.
