Overview

GCS Low-voltage withdrawable type complete switchgear (hereinafter referred to as the "switch equipment") is my company to meet the requirements of the design unit and power users design developed in line with the national conditions, with high technical performance indicators and can adapt to power market development needs and can compete with the introduction of existing product low voltage draw-out switchgear.
1.Rating: Rated voltage 400V, 690V, rated current reach to 4000A.
2.Application: mainly applicable in place with high automaticity and need to communicate with computer, like large power station and petrochemistry system, as the low voltage distribution device of the distribution and motor controlling, and reactive power compensation in power system.
3.Level of protection IP30, IP40
4.Standard: IEC60439-1

Model Meaning


Working Conditons

1.Ambient air temperature: -15℃~+40℃
Daily average temperature: ≤35℃
When the actual temperature exceed the range, it should be used by reducing thecapacity accordingly.
2.Altitude: ≤2000m
3.Relative humidity: ≤50%, when temperature is +40℃
When temperature is low, larger relative humidity is allowed. when it is +20℃,relative humidity can be 90%. Since the temperature change will make out condensation.
4.Installation inclination: ≤5%
5.Applicable in the places without corrosive and flammable gas.
Note: Customized products are available
