This switchgear is applicable to the power distribution systems in the industries of power generation, petroleum, metallurgy, textile, and high-rise buildings, where the sites are highly automated and connected with computers, such as the large power generating plants and the petrochemical system etc. It is a low-voltage complete-set distribution equipment for power distribution, motor centralized control and reactive power compensation in the power generation and supply systems when conditions are three-phase AC frequency of 50(60) Hz, rated working voltage of 380V (400), (600) and rated current of 4000A and below.

The product can be customized according to your design requirements and field conditions.

Operating conditions

Ambient air temperature upper limit +40 ○C, lower limit -5 ○C; Daily mean temperature no higher than +35○C; Please down-scale the operation capacity as necessary, when the ambient air temperature exceed the limits.

For in-door installation, Altitude above sea level: no higher than 2000 meters.

Relative environment humidity: daily mean value no higher than 50% when air temperature reaches +40 ○C; higher humidity is allowed when the air temperature become lower, for example, when air temperature is +20 ○C, humidity can reach 90%. The effect of condensation which maybe incidental to temperature change shall be considered. 

When installing, the vertical plane inclination shall be no more than 5% and the whole group of cabinet column shall be flat (according to GBJ232-82 standard).

Equipment should be installed at a place where there is no severe vibration, shock or corrosion.

For special requirements, please consult with the manufacturer.
