KSN1-12(KYN39-12) Indoor Metal-clad Two-layer Draw-out Type Switchgear
General of KSN1-12(KYN39-12) Indoor Metal-clad Two-layer Draw-out Type Switchgear:
KYN39-12 Type Indoor Metal-clad Two-layer Draw-out switchgear (Here in after called as switchgear) is a new series of power distribution product which designed and manufactured by our company. The structure of the switchgear is two-layer and the main switch can use VS1 type vacuum circuit breaker, and VD4 type vacuum breaker & VRC vacuum contactor of ABB Company. The product meets the GB3906-1991 and IEC298 standards, and it has the “five protection” interlock function which was put forward by the two ministries. Meanwhile, it has the features of light weight, long service life, low breaking voltage, reliable operation, no explosion and fire risks, etc.
This switchgear is a whole set of indoor power distribution devices and it suits to 3-phases AC 3~10kV, 50Hz single bus-bar and single bus-bar piecewise system. It is mainly used to protect and monitor the power transmission in power plant, medium and small-sized generator, and power distribution in industrial and mining enterprises, and power feeding and supplying in the secondary substations and large-scale HV motors of power supply systems.
