GCK Series Low Voltage Drawable Switchgear
Detailed description
GCK Series LV Drawable Switchgear
General
GCK Series Low Voltage Drawable Switchgear is a newly developed product of our company by absorbing the advanced technology of the same type of products abroad and improving them. This kind of switchgear, three-phases 4 wires or three-phase 5 wires system, 50Hz or 60 Hz (AC), rated voltage 660V, rated current up to 4000A, is widely used in power transmission and distribution net for power distribution, lighting, motor protection and power supply in power plants, substations, works, mining, building, hotels, airports, seaports, etc.
Structure
1,Compact. space saving design.
2,High generalization in structure design and flexibility in make-up the type FA steel with 20mm modular interval can meet the all needs of varied kinds of structure, protection degree, environmental condition.
