    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.
