Medium Voltage Switchgear KYN28A Metal - Clad Mid - Mounted AC Switchgear
Overview
KYN28A-12 Indoor Metal–clad Mid–mounted Switchgear (hereinafter called as “switchgear”), is a 3~10kV three phase AC 50 Hz complete distribution device of single busbar and its sectional system. It is mainly used to control, protect, and supervise circuits for the power supply of plant, medium or small generator, distribution of factory and mining, as well as power acceptance and transmission from the secondary substation in the power system, starting of large HV electromotor and so on. The product can meet IEC298,GB3906 standards. It has the functions to prevent from moving the handcart of circuit breaker alive, opening and closing circuit breaker by mistakes, or doing it while the earthing switch is at closing position, entering the alive chamber, as well as the closing interlock of earthing switch by mistakes while it is alive .The product can be used together with VS1, VD4, VB2, 3AH5, 10-VPR vacuum circuit breaker, it is a superior power distribution unit for performance.
