General:KSN1-12(KYN39-12) Metal-clad Two-layer Draw-out Type Switchgear is a kind of indoor complete set of electric
apparatus with 3~10kV, three phases alternative current 50Hz single busbar and single busbar segment
system. It is mainly used in power plants, industrial and mining enterprise for power distribution, and for power
feeding and electric power supply in the secondary substation of power supply system. And in big-size HV motor
starting fields, it could be used as controlling, protection and monitoring. This switchgear is two-layer structure
matched with inner main switch, which could be VT2 vacuum circuit breaker and ZN18-12 vacuum circuit
breaker, or VD4 vacuum circuit breaker and VRC vacuum circuit breaker by ABB. It meets specification of
GB3906-91, IEC298 standard and having 5-protective functions and it features:
* Compatible with circuit breaker switch cubicle and F-C switch cubicle.
* Specially designed switchgear in order to reduce occupied area of substation.
* Matched excellent vacuum circuit breaker and contactor, soithasmiddle mounted switchgear function.
* Adopting international fashioned combination structures, completely metal-clad, so it satisfies complete
separated.
* Aluminum zinc coated steel plate enclosure is not necessary to do any surface treatment to meet requirements
of anti-corrosion.
* Satisfying IEC298 and GB3906-91 standards, it is an ideal product, which could be instead of imported
products.
