(3) Technical advantages of NXAirS
1. Passed the type test, in line with GB3906 and DL404 (insulation), IEC62271-200 standards
2. Modular structure, each compartment has an independent pressure release channel (high pressure room, busbar room, cable room and low voltage room can be replaced separately)
3. The steel plates between the compartments can withstand the gas pressure generated by the internal arc fault, and the internal arcing of the switchgear conforms to the IAC A FLR standard
4. All operations must be carried out with the high-pressure chamber door closed, and the high-pressure chamber door is equipped with a reliable interlocking mechanism
5. Reliable "five-proof" mechanical interlocking mechanism
(4) Typical use
NXAirS air-insulated, removable metal armored medium voltage switchgear is used in substations and power distribution systems, mainly for 7.2-12kV primary power distribution systems.
1. Petroleum, chemical industry, metallurgy, machinery, textile, pharmaceutical industry
2, rail transit, water supply, sewage treatment project
3. Power supply company
4, high-rise buildings, commercial buildings, hospitals, scientific research institutions
