summary
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.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.Normal operating conditions
The switchgear is fundamentally designed for the normal service conditions for indoor switchgear to GB 3906, DL/T404 and IEC 62271-200. Advantage
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.
Maximum Safety For Operator And Equipment
The minimum functional pressure of the cubicle is 0.00MPa(20ºC ). 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.

Vacuum circuit breaker is fixed mounted, while its three-phase embedded poles are arranged vertically into the circuit breaker gas tank.
Due to the vacuum switching technology, an arc is limited in the vacuum interrupter, reducing the exhaust volume of insulation gas. Vacuum switching is of high performance in frequent short-circuit and numerous on-load switching applications.
The vacuum interrupter of the VCB is of an optimized design, the ceramic insulator is compact with high insulation level and a high current breaking capability. The contacts are made of Copper-Chromium, with excellent abrasion resistance, long electrical endurance, and high short circuit breaking capacity.
The embedded poles are assembled on the flange plate of the frame. The vacuum interrupter and terminals are fixed inside the embedded pole by APG epoxy molding process.
