Our GCS type low voltage extraction switch cabinet is used in power supply, power distribution, motor centralized control and capacitor compensation in the power supply system. Thermotics Inc is widely used in boiler room, heat exchange station etc. distribution room, can also be used in large power plant, such as a high degree of automation in petrochemical system, and computer interface places. This product meets the requirements of GB7251.1-2013 "low voltage switchgear and control equipment" and JB/T9661 "low voltage extraction type switchgear"
Structure characteristics：
1) the framework adopts 8MF type open type steel, the main frame is installed with modulus of E=20mm and 100mm of phi 9.2mm installation holes, making the frame assembly flexible and convenient.
2) Each function room of the switch cabinet is isolated from each other, and the compartment is divided into function unit room, bus room and cable room. The functions of the chambers are relatively independent.
3) the horizontal bus adopts the arrangement arrangement after the cabinet, in order to enhance the ability of the bus to resist electric power, it is the basic measure that the main circuit has the ability of short circuit strength.
4) the design of the cable compartment makes it convenient for the cable to go in and out.
5) the module height of the drawer is 160mm. Drawer changes vary only in height, size, width, depth, and dimension. The drawer of the same function unit has good interchangeability. Unit circuit rated current 400A and below.
