GCS High and low voltage draw out switchgear

Overview

GCS low-voltage withdrawable switchgear is suitable for power distribution systems in power plants, petroleum, chemical, metallurgy, textile, high-rise buildings and other industries. In large power plants, petrochemical systems and other places with a high degree of automation and requiring interface with computers, it can be used as a power generation and power supply system with a three-phase AC frequency of 50 (60) Hz, a rated working voltage of 400V, 660V, and a rated current of 5000A and below. A low-voltage complete set of power distribution devices used in power distribution, motor centralized control, and reactive power compensation. The design of the device complies with the following standards: IEC439-1 “Low-voltage switchgear and control equipment” GB7251 “Low-voltage switchgear”.

Model Meaning

Normal use environment

◆The ambient air temperature should not be higher than +40℃, not lower than -5℃, and the average temperature within 24 hours should not be higher than +35℃. When it exceeds, the derating operation shall be performed according to the actual situation;
◆For indoor use, the altitude of the place of use shall not exceed 2000m;
◆The relative humidity of the surrounding air does not exceed 50% when the maximum temperature is +40°C, and a relatively large relative humidity is allowed at a lower temperature, such as 90% at +20°C. produce condensation effects;
◆When the device is installed, the inclination of the vertical plane should not exceed 5°, and the entire group of cabinets should be relatively flat (in line with GBJ232-82 standard);
◆The device should be installed in a place without severe vibration and shock and not enough to cause the electrical components to be corroded;
◆When users have special requirements, they can negotiate with the manufacturer.
