GCS low voltage draw out switchgear is used in power generation and power supply systems with three-phase AC frequency of 50Hz, rated working voltage of 400V (690V) and rated current of 4000A and below as power, power distribution, centralized motor control and capacitance compensation. It is widely used in power plants, petroleum, chemical industry, metallurgy, textile, high-rise buildings and other places. It can also be used in large power plants, petrochemical systems and other places with high automation and requiring computer interface.

结构特点：

Structural features:

1、框架采用8MF型开口型钢，主构架上安装模数为E=20mm和100mm的Φ9.2mm的安装孔，使得框架组装灵活方便。

1. The frame adopts 8MF open section steel, and the main frame is installed with modules e = 20mm and 100mm Φ 9.2mm mounting hole makes the frame assembly flexible and convenient.

2、开关柜的各功能室相互隔离，其隔室分为功能单元室、母线室和电缆室。各室的作用相对独立。

2. Each functional room of the switch cabinet is isolated from each other, and its compartment is divided into functional unit room, bus room and cable room. The function of each chamber is relatively independent.

3、水平母线采用柜后平置式排列方式，以增强母线抗电动力的能力，是使主电路具备高短路强度能力的基本措施。

3. The horizontal bus is arranged horizontally behind the cabinet to enhance the ability of bus to resist electric power, which is the basic measure to make the main circuit have high short-circuit strength.

4、电缆隔室的设计使电缆上、下进出均十分方便。

4. The design of cable compartment makes it very convenient for cables to enter and exit up and down.

5、抽屉高度的模数为160mm。抽屉改变仅在高度尺寸上变化，其宽度、深度尺寸不变。相同功能单元的抽屉具有良好的互换性。单元回路额定电流400A及以下。

5. The module of drawer height is 160mm. The drawer changes only in height, and its width and depth remain unchanged. Drawers with the same functional units have good interchangeability. Rated current of unit circuit is 400A and below.

6、抽屉面板具有分、合、试验、抽出等位置的明显标志。抽屉单元设有机械联锁装置。1抽屉单元为主体，同时具有抽出式和固定性，可以混合组合，任意使用。

6. The drawer panel shall be provided with obvious marks of opening, closing, test, extraction and other positions. The drawer unit is equipped with mechanical interlocking device. 1. The drawer unit is the main body and has both drawout and fixation. It can be mixed and combined for arbitrary use.

7、柜体的防护等级为IP30IP40，还可以按用户需要选用。

7. The protection grade of the cabinet is ip30ip40, which can also be selected according to the needs of users.
