Cubicle type gas insulated switchgear(CGIS) is an indoor, factory-assembled, metal-enclosed, cubicle type gas-insulated switchgear for single busbar applications, including “Green Type” GPN2E-40.5, GPN2N-40.5 and “Standard Type” GPN2S-40.5.
The “Green type” GPN2N-40.5 is innovated to use pure nitrogen as insulation gas for the series product with Non-SF6 gas insulation technology, which has brought the genuine green environmental protection of gas insulated switchgear.
The “Green type” GPN2E-40.5 incorporates the advanced technologies of mixed gas-insulated (SF6+N2) and vacuum breakers, allowing the equipment to operate in a more reliable and environmentally friendly manner.
The “Standard type” GPN2S-40.5 is of 100% SF6 insulated, high performance and easy use. With modern digital manufacturing and automatic testing coupled with sensor, monitor and protection technology, CGIS is ideal fit for power distribution demands. CGIS is particularly suited to industries with high reliability requirements such as Power Networks, Mining, Rail Transportation, Petrochemical Plants, Wind Farms and Metropolitan Rail Systems.
The switchgear is fundamentally designed for the normal service conditions for indoor switchgear to GB 3906, DL/T404 and IEC 62271-200.

Maximum safety for operator and equipment: The minimum functional pressure of the cubicle is 0.00MPa(20℃ ). 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.
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.
Easy installation / Low operation and maintenance cost: Panels in the middle can easily be removed for maintenance without moving neighbouring panels, increasing availability.
