Outline

GCS LV with drawable switchgear(hereinafter referred to as device) is developed according to the requirements from industry  competent department, numerous electric users and design unit by original state mechanical department, united design group of  power department. It conforms to national conditions and with higher technical performance index, and adapts the demands for  power market development and able to compete with available imported products. The device passed the authentication jointly  presided by two departments in July 1996 in Shanghai. It obtains the recognition and affirmation from manufacturing unit and  power consumer construction. The device is applicable to the distribution system of power station, petroleum, chemical engineering, metallurgy, weaving  and tall building industriesetc. In the places with high automaticity and need computer to joint, such as large-scale power station  and petrochemical industry system etc, it is the low voltage complete distribution device used in the generating and power supply  system with three-phase AC50(60)Hz, rated working voltage 380V, rated current 4000A and below for distribution, motor central  control and reactive power compensation.  The device accords with standards IEC439-1 and GB7251.1.

Use environmental conditions

1. Ambient air temperature: -5℃ ~+40℃ and the average temperature should not exceed +35℃ in 24h. 

2. Relative humidity should not exceed 50% at max temperature. Higher relative humidity is allowed at lower temperature. Ex. 90%  at +20℃ . But in view of the temperature change, it is possible that moderate dews will produce casually. 

3. Altitude above sea level should not exceed 2000M.

4. Installation gradient not exceed 5° . 

5. Indoor without dust, corrosive gas and rain water attack.
