KYN28A-7.2(F-C)

Armoring move open AC metal-enclosed switchgear

KYN 28a-7.2(F-C) armoring move open ac metal-enclosed switchgear(hereinafter referred to as switching device) is by our company on its own research and development of medium voltage switchgear. The product is ac high voltage vacuum contactor and ac high-voltage current-limiting fuse as the main component of switch devices, also known as F-C circuit switch cabinet(also called integrated starter cabinet), frequent in large capacity, small current and open circuit system compared with the vacuum circuit breaker cabinet, has excellentcost performance. As 7.2 kV rated voltage, rated frequency 50 hz indoor distribution equipment in the power system, is widely used in power plants, mining. metallurgy, chemical and other industries control and below 200 kw electric motor protection, below 1600kva transformer.
