Low Voltage Switchboard Draw - Out Switchgear Electric Distribution Panel
Overview
GCS low voltage draw-out switchgear (hereinafter referred to as the device) is a low voltage draw-out switchgear which is designed and developed jointly by the Ministry of Power Industry and the Ministry of Machine Building together with Design Team in accordance with the requirements of competent industry department, power consumers and design unit, accords with national situation of China, has high technical index and can adapt to the development needs of power market and compete with current imported product.
Working condition
1. The ambient air temperature shall not be higher than ±40℃ and not be lower than -5℃,and the average temperature within 24h shall not be higher than +35℃. If the temperature exceeds the above value, the device shall run with reduced capacity.
2. When the air is clean, the relative humidity shall not exceed 50% at +40℃, and it may be higher at lower temperature, for example, 90% at +20℃. Then impact of condensation resulting from temperature variation should be considered.
3. The inclination of equipment shall not exceed 5° at installation. The height above sea level in the place of use may not exceed 2,000m.
4. The medium shall be free from explosive hazard and not contain the gas and conducting dust which may corrode metals and destroy the insulation.
5. The user's special requirements may be solved through consultation with the company.
