Application
GCS low-voltage withdrawable switchgear, also called low-voltage drawer cabinet, is a modular, versatile, and high-performance electrical cabinet system. Power users widely use drawer-type cabinet, which is suitable for power distribution systems in industries such as power plants, petroleum, chemical, metallurgy, textiles, and high-rise buildings. It is especially ideal for large power plants and petrochemical systems where high automation and computer interfacing are required. The switchgear is used in power generation and distribution systems with rated voltages of 380V or 660V and rated currents of up to 4000A, providing power distribution, centralized motor control, and reactive power compensation. Our low-voltage withdrawable switchgear can compete with the existing imported products and has been widely used by power users.
The GCS series is ideal for AC three-phase 50Hz systems with rated voltage up to 690V and rated currents of up to 4000A.
It’s commonly used in power distribution systems for motor control centers (MCC), lighting distribution, and electrical equipment control.
Built to meet IEC 439-1 and GB7251.1 standards, ensuring compliance with international and regional safety regulations.

Product Features
1.Increase the heat capacity of the adapter, and greatly reduce the additional temperature rise caused by the temperature rise of the adapter to the connector, cable head, and spacer plate.
2.The separation between functional units and compartments is clear and reliable, and the failure of one unit does not affect the work of other units, so that the failure is limited to a minimum.
3.The horizontal arrangement of the busbar makes the device have good dynamic and thermal stability, and can withstand the impact of 80/176kA short-circuit current.
4.The number of circuits in a single MCC cabinet is as many as 22, and the needs of large single-unit power generation, petrochemical systems and other industries for automated electric door (machine) groups are fully considered.
5.The connection between the device and the external cable is completed in the cable compartment, and the cables can be entered and exited up and down. The zero sequence current transformer is placed in the cable compartment, making installation and maintenance easy.
6.GCS switchgear can accommodate a variety of components, such as circuit breakers, contactors, transformers, and instrumentation.
It can integrate with monitoring and automation systems, offering real-time data on electrical load and system status.
