Product description
GCS series are low voltage switchgear(MCC) suitable in the power generation system and power supply system with three-phase AC 50Hz, rated working voltage of 400V(660V) and rated current of 5000A and below for the collective control and capacitance compensation of power, power distribution and electromotor. It's widely applied in the power station, petroleum, chemical engineering, metallurgy, textile, high-rise buildings as well as the sites which have interface with computer with high automation degrees such as the large-scale power station, etc.
Construction features
1. Compact structure, less space installed with more function unit
2. Spare parts are universal, flexible assembly.
3. Adopting standard module design. 5 types of modules for user options.
4. High performance, rated short time withstand current of GCS panel is 80kA, Horizontal busbar arranged with counter flat mode, which can bear peak withstand current 176kA.
5. The partition between function unit / compartment is clear and reliable,there is no affect to adjacent units due to fault of one unit, ensure the fault only happened partially.
