the technical advantages of NXAirS

1, through the type test, in line with GB3906 and DL404 (insulation), IEC62271-200 standard

2, modular structure, each compartment has an independent pressure release channel (high pressure room, bus room, cable room and low pressure room can be replaced separately)

3, the steel plate between the compartments can withstand the internal pressure of the gas generated by the arc, the switch cabinet internal arc consistent with the IAC A FLR standard

4, all operations must be carried out in the case of high pressure chamber door closed, high pressure chamber door with a reliable chain

5, reliable "five anti" mechanical interlocking institutions

typical use

NXAirS air insulated, removable metal armored medium voltage switchgear for substations and power distribution systems, mainly for 7.2-12kV primary distribution system.

1, petroleum, chemical, metallurgy, machinery, textile, pharmaceutical industry

2, rail transportation, water supply, sewage treatment works

3, power supply company

4, high-rise buildings, commercial buildings, hospitals, research institutions
