GCS low-voltage withdrawable switchgear (hereinafter referred to as “switch Equipment”) is designed and developed by our company according to the requirements of the design unit and power users in line with national conditions, has high technical performance indicators, can meet the needs of the development of the power market, and can compete with the introduction of existing low-voltage products.

Product Description

This product has been widely used by power users. The switch cabinet is suitable for distribution systems in power plants, petroleum, chemical, metallurgy, textile, high-rise buildings and other industries. In large power plants, petrochemical systems and other places with a high degree of automation and requiring computer interfaces, it is used as a Low-voltage complete power distribution device for power distribution, motor centralized control and reactive power compensation in power generation and power supply systems. Three-phase AC frequency 50 (60) Hz, rated working voltage 380V (400V), (660V), rated current 4000A and below.
This product complies with GB7251 low-voltage switchgear and control equipment, JB/T9661 low-voltage lead-out switchgear and IEC439 low-voltage switchgear and control equipment standards.

Product technical parameters and external dimensions

Product structure features

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.The drawer unit has a sufficient number of secondary plug-ins (32 pairs for 1 unit and above, 20 pairs for 1/2 unit). It can meet the requirements of the number of connection points of the computer interface and the automatic control loop.
