Product Overview
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 centralized 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.
Enforce Standards
- IEC 439: Low-voltage switchgear and control equipment
- GB 7251: Low-voltage switchgear
Normal Service Condition
- The ambient air temperature shall not be higher than +40 degrees Celsius and not lower than -5 degrees Celsius, and the average temperature within 24 hours shall not be higher than +35 degrees Celsius. 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 location shall not exceed 2000 meters.
- The relative humidity of the ambient air shall not exceed 50% when the maximum temperature is +40 degrees Celsius. At lower temperatures, a higher relative humidity is allowed. For example, it is 90% at +20 degrees Celsius. 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 degrees, 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.
