2  Special Service conditions
The product can also be applied for many special service conditions.
In case the service conditions exceed the normal service conditions, which are out of the standard GB 11022 and IEC 62271-1, please consult with GP in advance for confirmation:
Altitude higher than 1000m.
Higher environmental temperature.
Lower environmental temperature.
Others special environmental conditions.

3  Executive standard
The switchgear is fundamentally designed for the normal service conditions for indoor switchgear to GB 3906, DL/T404 and IEC 62271-200.
 
4  CGIS Advantages
1) 70% Reduction In Switchroom Size
An optimized electric field design combined with excellent insulating performance, results in a compact switchgear product that operates safely and reliably.
Save 70% space compared with air-insulated switchgear.
Retrofitting into existing switchroom is easy.
Reduce cost of substation land.
2) Maximum Safety For Operator And Equipment
The minimum functional pressure of the cubicle is 0.00MPa(20 oC). That means, even under such severe conditions, it still maintains the rated insulation level and keeps all its rated functionality. Thanks to the low pressure of gas, even if gas is escaping from the switchgear, the cubicle can still continue to be energized. Reliable electrical and mechanical interlocks are designed between the circuit breaker and three-position switch to prevent misoperation.
Easy Installation/Low Operation And Maintenance Cost
Panels in the middle can easily be removed for maintenance without moving neighbouring panels, increasing availability.
