GCK Low-Voltage Draw-out Switchgear
The GCK low-voltage withdrawable switchgear is a type of switchgear assembled from C-profiles and standard components. It is suitable for power supply systems operating at AC 50–60 Hz with a rated operating voltage of 690 V or below. It is utilized in power plants, substations, metallurgical rolling mills, petrochemical facilities, light industry and textile plants, industrial and mining enterprises, office buildings and hotels, airports and terminals, public utilities, and civil structures to perform functions such as power distribution, control of motors and electrical equipment, lighting control, energy conversion, and power factor compensation; it serves as an ideal power distribution device for low-voltage power supply systems.
