GCK GCS Low-Voltage Switchgear, Low Voltage Capacitor Bank , Metal Enclosed Distribution Cabinet China TOP 500 Company
GCS drawable low voltage electrical switchgear assembled from modular components from a combination of low-voltage switchgear withdraw-able type. This device is suitable for power plants, transformer substation, petrochemical, metallurgy, steel rolling, light industry and textile factories and enterprises, and residential quarters, high-rise buildings and other places.
Type GCS low-voltage withdrawable type switchgear is a blend of the other advantages of low voltage products and the development of advanced products, applicable to power plants, petrochemical industry, metallurgy, telecommunications, light industry, textile, high-rise buildings and other civil and industrial and mining enterprises of power distribution system, in large power plants, petrochemical, telecommunication system, etc. A high degree of automation, and computer interface, as the motor centralized-control hair, power supply system of power distribution, low-voltage distribution of reactive power compensation device.
Structural features
1. Internal structure galvanized, external pickling phosphating.
2. The cabinet is made of profiled steel and positioned by a 3-dimensional gusset plate.
3. The mounting holes of the bar frame and parts change according to the modulus E=25mm.
4. The motor control center (MCC) switchgear has two types: wall-mounted and not wall-mounted. The top is the
horizontal busbar area, and the horizontal area is the drawer functional unit area.
5. The structure of the power center (PC) feeder cabinet is similar to that of the incoming line cabinet. When the
feeding current is 630A~1600A, a cabinet of 1000*1000*2200 (width*deep*height) can be installed with two circuits,
which are installed up and down.
6. The drawer function unit and the door are mechanically interlocked by the operating mechanism of the main switch. The functional unit compartments are separated by metal loose, the drawers are interchangeable and have a working
position, a test position and a separation position.
Conditions of use
1.For indoor use, the elevation of the service point shall not exceed 2000m.
2.The ambient air temperature is no higher than +40 degrees and no lower than -5 degrees.The average temperature should not be higher than +35 degrees within 24 hours.When exceeding, the capacity should be reduced according to the actual situation.
3.The relative high temperature of the surrounding air is +40 ° c and does not exceed 50%.If +20 degrees is 90%, consideration should be given to the effect of occasional condensation caused by temperature changes.
4.When the device is installed, the tilt with the vertical plane shall not exceed 5°, and the whole set of cabinets shall be relatively flat in line with the standard of gbj232-2.
5.The device shall be installed in a place free from violent vibration and shock and where the electrical components are not sufficiently corroded for use
