Product Description

Product Description

 

Switchgear Cabinet
MV &LV Switchgear is mainly applicable to power plants, power transmitting of middle and small size generators, distribution of industrial and mine enterprises, electricity receiving and transmitting of secondary substations, as well as starting of motors etc, realizes control protection and monitoring.

It prevents on-load pushing or pulling breaker handcart, prevents making or breaking breaker by mistake, prevents closing breaker when the earthing switch is on closing position, prevents entering into live compartment by mistake, and prevents closing earthing switch under live condition.
 
Applicable Environment:

1 - Ambient air temperature: -15°C - +40°C
2 - Altitude: ≤1000m
3 - Relative humidity: daily≤95%, monthly ≤90%
4 - Seismic intensity: ≤Ms8
5 - Installation site should be free of fire, explosive danger, serious pollution, chemical corrosion or severe vibration.

Fields of application

1 - Transformers and distribution substations
2 - Generator control and protection

3 - Capacitor bank control and protection, etc

Standard:

GB 3906, GB/T 11022 and IEC 60298.
