GCS low-voltage withdrawable switchgear has a wide range of applications,mainly including the following aspects:
1) Industrial sector: such as manufacturing factories, used to provide stable and reliable power distribution and control for various production equipment and automated production lines.
2) Power system: Achieve the distribution, monitoring, and protection of low-voltage electrical energy in substations, distribution stations, and other places.
3) Commercial buildings: such as office buildings, shopping malls, hotels, etc., provide power and control for electrical equipment such as lighting, air conditioning, elevators, etc.
4) Data center: Ensure the power supply and management of key facilities such as servers and network equipment.
5) Petrochemical industry: used for power distribution and control in chemical plants, refineries, and other places, meeting special requirements such as explosion prevention.
6) Sewage treatment plant: provides power support and control for various treatment equipment, pump stations, etc.
7) Rail transit: Ensure the normal operation of electrical systems at subway stations, railway lines, etc.
1) Improve the heat capacity of the adapter, and greatly reduce the additional temperature rise caused by the temperature rise of the adapter to the connectors, cable logs and spacers.
2) The separation between functional units and compartments is clear and reliable, and the failure of one unit will not affect the work of other units so as to minimize the failure.
3) The horizontal arrangement of the bus bar makes the device have good dynamic and thermal stability, and can withstand the impact of 80/1 76kA short-circuit current.
4) The number of circuits in a single MCC switchgear is as many as 22, which fully considers the needs of large single-unit power generation,petrochemical systems and other industries for automated motor groups.
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 current transformer is installed in the cable compartment to facilitate installation and maintenance.
6) The same power distribution system can limit the short-circuit current through the matching of current-limiting reactors, stabilize the bus voltage at a certain value, and partially reduce the short-circuit strength requirements of the components.
7) The drawer unit has a sufficient number of secondary connectors (32 pairs for 1 unit and above, 20 pairs for 1/2 unit), which can meet the requirements of the number of computer interfaces and automatic control circuits.

1) Improve the thermal capacity of the adapter and significantly reduce the additional temperature rise caused by the temperature rise of the adapter to the connectors, power heads, and partitions.
2) The separation between functional units and compartments is clear and reliable, and the malfunction of one unit does not affect the operation of other units, limiting the scope of the malfunction to the minimum.
3) The flat arrangement of busbars ensures good dynamic and thermal stability of the device, and can withstand the impact of 80/176kA short-circuit current.
4) The number of circuits in a single MCC cabinet can reach up to 22, fully considering the needs of electric door (machine) groups in industries such as large single capacity power plants and petrochemical systems.
5) The device is connected to the external electrical system in a cable compartment, and the cable can enter and exit vertically. The zero sequence current transformer is placed in the cable compartment for easy installation and maintenance.
6) The same power distribution system can be matched with current limiting reactors to limit short-circuit current, stabilize bus voltage at a certain level, and partially reduce the requirements for short-circuit strength of components.
7) The drawer unit has a sufficient number of secondary connectors (32 pairs for 1 unit and above, and 20 pairs for 1/2 unit) to meet the requirements of computer interface and automatic control circuit docking points.

The following is the installation guide for GCS withdrawable switchgear:
1) Preparation before installation
-Confirm that the installation site meets the environmental requirements of the switchgear, such as temperature, humidity, dust prevention, shock resistance, etc.
-Check the integrity of the switchgear and its accessories to ensure that there are no damaged or missing parts.
-Prepare the necessary installation tools and equipment, such as cranes, wrenches, screwdrivers, etc.
2) Basic installation
-Produce the foundation of the switchgear according to the design requirements, ensuring that the foundation is level and firm.
-Place the switchgear on the foundation, adjust the levelness and verticality, and fix it with bolts.
3) Connection of incoming and outgoing lines
-According to the electrical schematic, connect the incoming and outgoing cables to the corresponding terminals of the switchgear, ensuring a secure connection and good contact.
-When wiring, attention should be paid to the bending radius of the cable to avoid damaging the insulation of the cable.
