High and Low Voltage Switchgear
Low Voltage Switchgear GCK
- Ambient temperature: High temperature 45°C, low temperature -35°C
- Daily temperature difference: No more than 25°C
- Earthquake tolerance: Earthquake intensity does not exceed 8°C
The GCK low-voltage switchgear is suitable for use in power plants, metallurgical rolling, petrochemical industries, light industry and textiles, electric power, machinery, docks, hotels, and other locations. It is designed for three-phase four-wire or three-phase five-wire systems, with a rated operating voltage of 380V (400V) or 660V, a rated current of up to 4000A, and a rated frequency of 50Hz (60Hz) for power distribution and motor control in electrical systems.
Introduction of Low Voltage Switchgear GCK
Some structural features of Low Voltage Switchgear GCK:
- GCK’s basic cabinet frame is designed as a modular assembly structure. The frame is made of hot-rolled steel (STHC), and the FA profiles are positioned using angle plates and connected with bolts, resulting in a non-welded structure. The forming dimensions, hole sizes, and equipment clearances of the components are standardized to modular dimensions.
- The internal structural components are treated with galvanization.
- The external structural components are treated with acid pickling and phosphating, followed by high-pressure electrostatic spraying.
- The structural components have strong versatility and high mechanical strength.
- The upper part of the cabinet is the main busbar chamber, the front part is the electrical chamber, and the rear part is the cable entry and exit chamber. Steel plates or insulating boards are used for isolation between the chambers to ensure safe operation.
