The GCS type low-voltage withdrawable switchgear is suitable for use in power generation and supply systems with a three-phase AC frequency of 50Hz, a rated operating voltage of 400V (690V), and a rated current of 4000A and below, as a power distribution and motor centralized control, and capacitor compensation. Widely used in power plants, petroleum, chemical, metallurgical, 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 computer interface requirements.

1.The frame adopts 8MF open steel, and the main frame is equipped with installation holes of E=20mm and 100mm with a diameter of 9.2mm, making the frame assembly flexible and convenient.

2.The various functional rooms of the switchgear are isolated from each other, and their compartments are divided into functional unit rooms, busbar rooms, and cable rooms.The functions of each room are relatively independent.

3.The horizontal busbar adopts a cabinet mounted flat arrangement to enhance its ability to resist electric forces, which is a basic measure to make the main circuit have high short-circuit strength.

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

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

6.The drawer panel has clear markings for opening, closing, testing, and withdrawing positions. The drawer unit is equipped with a mechanical interlocking device. The drawer unit is the main body, with both pull-out and fixed functions, and can be mixed and combined for any use.

7.The protection level of the cabinet is IP30 IP40, and it can also be selected according to user needs.
