Product Details

Purpose:The GCS system is suitable for distribution systems in power plants, petroleum, chemical, metallurgical, textile, and high-rise building industries. It can be used as a low-voltage complete distribution device for distribution, motor centralized control, and reactive power compensation in power generation and supply systems with three-phase AC frequency of 50/60Hz, rated working voltage of 380/400/660V, and rated current of 4000A and below.

Structural features:
The main framework of the device is made of 8MF steel, and the framework adopts two structural forms: assembly and partial welding. There are modular holes E=20mm installed on the main structure
2. Each functional room of the device is strictly separated, and its compartments are mainly divided into functional unit rooms, busbar rooms, and cable rooms. The functions of each unit are relatively independent.
3. The drawer only changes in height, while its width and depth remain unchanged. Drawers with the same functional unit have good interchangeability.
