Indoor Gas Insulation Metal-clad Switchgear (C-GIS), XGN75-12(Z)
General of Indoor Gas Insulation Metal-clad Switchgear (C-GIS), XGN75-12(Z)
XGN75-12 (Z) Indoor gas insulation metal-clad switchgear is designed and developed by our company self and adopted permanent magnet mechanism vacuum circuit breaker as main switch and HV live conductor is full-enclosed in SF6 room. It is suitable as a new generation metal-clad switchgear automatic-distribution, compact and able to extend.
This switchgear conforms to IEC 62271-200 and all primary components employed therein are in accordance with the relevant standards.
It is designed to accommodate high performance vacuum circuit breaker (VCB) which has been designed and tested in accordance with IEC62271-100.
The switchgear panels are suitable for the assembly of single &double busbar systems for indoor installation.
Characteristic of Indoor Gas Insulation Metal-clad Switchgear (C-GIS), XGN75-12(Z)
1. Reliable
Each compartment is monitored individually &has its own pressure relief device.
Use of Vacuum circuit breakers with high number ofmechanical & electrical operations
Robust interlocking system
2. Safety
The primary side components are hermetically enclosed, gas filled compartment and thus insensitiveto 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
