Factory Sale GCS /GCK Low Voltage Switchgear Automatic Electrical Panels/ Low Voltage Switchgear Switch Cabinet
Products Description
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.
GCS low-voltage withdrawable switchgear is composed of two parts: power center cabinet (PC) and motor control
center cabinet (MCC). It is suitable for AC 50Hz-60Hz, rated working voltage 690V and below, for all power
generation/distribution and power use occasion.
GCS low-voltage withdrawable switchgear is widely used in power plants, substations, power distribution centers ,
factory and mining enterprises and high buildings.
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.

Working Environment
1. Indoor altitude above sea level: Maximum installation altitude: 2000m
2. Ambient air temperature: -5℃~+40℃ and the average temperature should not
exceed +35℃ in 24h
3. Relative humidity should not exceed 50% at max temperature +40℃. Higher
relative humidity is allowed at lower temperature. Ex. 90% at +20℃. But in view of
the temperature change, it is possible that moderate dews will produce casually.
4. No fire, explosion danger, serious pollution, chemical corrosion and severe vibration
5. Installation gradient not exceed 5°
6. This product is suitable for the following temperature transportation storage: -25℃ ~+55℃ 24h, in a short period of time (no more than 24hours) not more than+70℃.
