3. Feature of XGN75-12KV C-GIS Indoor Gas Insulation Metal-clad Switchgear
(1). Reliable
• Each compartment is monitored individually &
has its own pressure relief device.
• Use of Vacuum circuit breakers with high number of
mechanical & electrical operations
• Robust interlocking system
(2). Safety
• The primary side components are hermetically
enclosed, gas filled compartment and thus insensitive
to atmosphere, dirt &dust.
• Current transformer are mounted outside the gas
compartment & mounted on earthed LV compartment
(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
