Product Description
Product Summary
GCS low Voltage withdrawable switchgear is suitable for the low voltage distribution system in power plant, petroleum industry, chemical industry metallurgy industry, spinning mill, high buildings, etc. lt is especially used in large power plant,petrochemical system and other locations which are required high automatic and computer interface. lt is serviced in the low voltage apparatus distribution devices of generator and power supply system distribution, motor central control and reactive power compensate of3 phase AC 50/60Hz,400V,rated current 4000A and lower.
Environmental Conditions
- Ambient Temperature: No more than +40C and no less than -15C.Averagetemperature is no more than +35C within 24 hours.
- Altitude: No more than 1000m.
- Relative Humidity: the average daily value is no more than 95%, theaverage monthly value is no more than 90%.
- Earthquake Intensity: No more than 8 degrees.
- Vapor pressure: average daily value is no more than 2.2kPa, averagemonthly value is no more than 1.8kPa.
- Installation locations without fire,explosion danger, serious pollution.chemical corrosion and violent vibration.
Product Features
- lt can be increased the thermal capacity of adaptor parts. Also it can beeffectively and evidently reduced the temperature rise of adaptor parts or additional temperature rise of cable lug and partition board.
- The quantity of a single MCC panel’ s loop is up to 22 Nos., this can satisfyrequirements of power plant which has high capacity of single generator automatic motor control door (machine) set of petrochemical system an
- The connection between the device and the external cable is completed inthe cable compartment, and the cable can get in and out on the top or The zero sequence current transformer is placed in the cable compartment, so that the installation and maintenance are convenient.
- Drawer units have enough quantity secondary adaptors (32 pairs for 1 unitand above, 20 pairs for 1/2 unit), so it can meet the requirements of the number of contacts by the computer interface and the automatic control

Product Advantages
- The frame is made of 8MF open section steel, and the main frame is installed with Φ9.2mm mounting holes of E=20mm and 100mm, which makes the frame assembly flexible and convenient.
- The functional rooms of the switch cabinet are isolated from each other, and the compartments are divided into functional unit rooms, bus rooms and cable rooms. The function of each chamber is relatively independent.
- The horizontal bus adopts the flat arrangement mode behind the cabinet to enhance the ability of the bus to resist electric power, which is the basic measure for the main circuit to have high short-circuit strength.
- The design of the cable compartment makes the cable up and down are very convenient.
- The module of the drawer height is 160mm. The drawer changes only in the height size, and its width and depth dimensions remain unchanged. The drawers of the same functional unit have good interchangeability. Unit circuit rated current 400A and below.
- The drawer panel shall have clear marks for the position of parting, closing, testing, and pulling out. The drawer unit has a mechanical interlocking device. 1 drawer unit as the main body, at the same time with withdrawable and fixed, can be mixed and combined, arbitrary use.
- The protection level of the cabinet is IP30 IP40 and can also be selected according to user needs.
Application Places
The device is suitable for power conversion, distribution and control of power, distribution and motor control center, capacitance compensation of low-voltage power distribution system in power plants, substations, petrochemical departments, factories and mining enterprises, high-rise buildings, etc.
