GCS

The GCS low-voltage withdrawable switchgear is applicable to the power distribution systems of industries such as power plants,petroleum, chemical engineering, metallurgy,textile, and high-rise buildings.

In places with high automation requirements such as large-scale power plants and petrochemical systems,which require interfaces with computers, it serves as a low-voltage complete power distribution device for the centralzed control of distribution motors and reactive power compensation in power generation and power supply systems with a three-phase alternating current frequency of 50(60)Hz, a rated working voltage of less than 1kV, and a rated current of 6300A or less.

Type description

Normal service condition

The ambient air temperature shall not be higher than +40℃ and not lower than -5℃, and the average temperature within 24 hours shall not be higher than +35℃. When these limits are exceeded, the capacity shall be derated for operation according to the actual situation.

It is for indoor use, and the altitude of the installation locatin shall not exceed 2000m.

The relative humidity of the ambient air shall not exceed 50% when the maximum temperature is +40℃. At lower temperatures, a higher relative humidity is allowed. For example, it is 90% at +20°℃. The influence of occasional condensation caused by temperature changes should be taken into account.

When the device is installed, the inclination from the vertical plane shall not exceed 5°, and the entire group of cabinet rows shall be relatively flat.The device shall be installed in a place without severe vibration and impact, and where the electrical components will not be subject to undue corrosion.
