GCS Low Voltage Withdrawable Switchgear
GCS low-voltage withdrawable switchgear is suitable for power distribution systems in power plants, petroleum, chemical, metallurgy, textiles, high-rise buildings and other industries. In large power plants, petrochemical systems and other places with a high degree of automation and computer interface, as a three-phase AC frequency of 50 (60) Hz, rated working voltage of 380V (400V), (660V), rated current of 4000A and below. The low-voltage complete set of power distribution devices used in power distribution, motor centralized control and reactive power compensation in the power supply system.
The main frame is made of 8MF open section steel, and the two sides of the section steel have mounting holes with modules of 20mm, 100mm and 9.2mm respectively, which is flexible and convenient for internal installation; The main frame assembly form is designed as two types, fully assembled structure and part (side frame and beam) welded structure for users to choose;
The functional chambers of the device are isolated from each other, and their compartments are divided into functional unit rooms, bus rooms and cable rooms;The role of each chamber is relatively independent;
The horizontal main bus adopts the horizontal arrangement mode behind the cabinet to enhance the ability of the bus to resist electric power, so that the main circuit of the device has the basic measures of high short-circuit strength ability;
The cable compartment is designed to make it easy to get cables in and out.

Ambient temperature: the temperature is not higher than +40 °C, not lower than -5 °C, and the average temperature is not higher than +35 °C within 24 hours; |
Atmospheric conditions: clean air, relative humidity does not exceed 50% at a maximum temperature of +40°C, and higher relative humidity is allowed at lower temperatures, e.g. 90% at +20°C, but temperature changes should be taken into account, with the possibility of occasional condensation; |
When the device is installed, the inclination with the vertical plane does not exceed 5°, and the whole group of cabinets is relatively flat (in line with the GBJ232-82 standard); |
The device should be installed in a place where there is no violent vibration and shock, and it is not enough to prevent the electrical components from being corroded; |
