Product overview
XGN2-12 cubicle fixed type alternating-current metal-enclosed switchgear (hereinafter referred to as switchgear) is an indoor complete set of distribution equipment for three-phase systems of AC50Hz and voltage 3.6-12kV, used for electric energy receiving and distribution, it controls, protects and monitors the circuits. Its bus system is of single-bus structure with bypass bus, from which dual-bus structure can be derived.
This switchgear complies with the standards GB3906 A.C. metal-enclosed switchgear for rated voltages of 3~35kV and IEC298, has a perfect mechanical anti-misoperation interlocking device that is featured with reliable performances, complete functions, simple structure, convenient operation, and "five-prevention" locking function.
Main switch of the switchgear adopts ZN28A-10 series vacuum circuit breaker that is equipped with CD17 series electromagnetic operating mechanism, CT17 or CT19B spring operating mechanism. It adopts CN30-10 rotary isolating switch series.
