GCS （Low Voltage Withdrawable Switchgear）
Model：
GCS
Overview：
The GCS Low Voltage Withdrawable Switchgear is a kind of combination type switchgear, usually used in the three-phase AC frequency of 50 Hz, the rated working voltage is 400 V (690 V), and the rated current is 4000 A and below in the power generation, and power supply systems as power, power distribution and centralized control of motors, and capacitor compensation. It is widely used in power plants, petroleum, chemical, metallurgical, textile, high-rise buildings, etc.
  1. The frame adopts 8MF type open-section steel, and the main frame is installed with E = 20mm and 100mm medium 9.2mm mounting holes, making the frame assembly flexible and convenient.
  2. The functional chambers of the switchgear are isolated from each other, and their compartments are divided into functional unit chambers, busbar chambers, and cable chambers. The functions of each chamber are relatively independent.
  3. The horizontal busbar adopts a rear-cabinet flat arrangement to enhance the ability of the busbar to resist electric power, which is a basic measure to make the main circuit have a high short-circuit strength ability.
  4. The design of the cable compartment makes it very convenient for the cable to enter and exit from top to bottom.
  5. The height of the drawer can be adjusted according to the multiple of the modulus 160mm, while the width and depth remain unchanged. The drawers of the same functional unit have good interchangeability. The rated current of the unit circuit is 630A and below.

  6. The drawer panel has obvious marks at positions including splitting, closing, testing, and extracting. The drawer unit is equipped with a mechanical interlocking device. The drawer unit is the main body and has both withdrawable and fixed features, which can be mixed and combined for arbitrary use.

  7. Implementation standards:
