KYN28A-12 Metal-clad Removable AC High-voltage Switchgear is a complete distribution device for 3–12kV, three-phase AC 50Hz single-busbar and single-busbar sectionalized systems. It is used in power plants, small- and medium-sized generator transmission, industrial/mining/enterprise power distribution, secondary substation power receiving and distribution in power systems, and large high-voltage motor starting, etc., to achieve control, protection, and monitoring functions. The switchgear can be equipped with ABB's VD4 vacuum circuit breaker or domestic VS1 vacuum circuit breaker, making it a high-performance distribution device.
