low voltage draw out type power distribution GCK switchgear
Features
GCK low-voltage withdrawable switchgear is widely used in power generation plants, substations, power
distribution centers PC and motor control center MCC of factory and mining enterprises and high-rise
buildings, as a low-voltage complete power distribution device for AC 50-60Hz, rated working voltage of
660V and below, rated current of 4000A and below, power distribution, motor centralized control, reactive
power compensation.In the three-phase three-wire or three-phase four-wire system, it is used as a substation
, feed or motor for low-voltage distribution systems. GCK low-voltage withdrawable switchgear has increased
its capacity and mechanical strength on the basis of maintaining higher electrical performance than similar
products, and has characteristics of advanced structure, beautiful appearance, high protection level, safety
and reliability, and easy maintenance; can be the update product of low voltage switchgear device.
