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.
