Description
The GCS series low-voltage draw-out switchgear is designed for AC 50/60Hz low-voltage distribution systems with a rated voltage range of 380V to 660V. It serves as core equipment for power distribution, conversion and control, and is widely used for both power distribution and motor control scenarios.
Key Structural Features
- The main cabinet frame is made of section steel, with standard 20mm-modulus mounting holes on both sides, enabling highly flexible internal assembly to adapt to various functional units.
- Adopting a draw-out functional unit design, units of the same specification are fully interchangeable, facilitating on-site maintenance and replacement and greatly reducing power outage duration during operation.
- The interior is divided into independent compartments including busbar chamber, functional unit chamber and cable chamber, which improves operational safety and fault isolation performance.
