Description

MV XGN2-12 Fixed Metal-enclosed Switchgear for Frequent Operation Occasions

MV XGN2-12 fixed metal-enclosed switchgear is used to receive and distribute power energy in electrical power system of three-phase, AC, 50 Hz and 3.6 kV, 7.2 kV and 12 kV voltage. It is especially suitable for frequent operation occasions. It meets the standards of GB3906 and IEC298. The main switch adopts ZN63-12 and ZN65A-12 integrated vacuum circuit breaker. Disconnecting switch adopts GN30-12 rotating disconnecting switch, GN22-12 high current disconnecting switch and GN30-12 rotating high current disconnecting switch.

The model and meaning of MV XGN2-12 fixed metal-enclosed switchgear.
Working conditions:

Altitude: ≤ 1000 m.
Temperature range: -25 °C to +40 °C.
Relative air humidity: daily: ≤ 95%, monthly: ≤ 90%.
