KYN28 indoor metal armoured draw-out switchgear (hereinafter referred to as switchgear) is a complete set of power distribution equipment for 3.6~24KV, three-phase AC 50Hz, single bus section system. It is mainly used for the transmission of small and medium-sized generators in power plants, the distribution of plants, mines and enterprises, and the power receiving and transmission of substations in the power system, and the start-up of large high-voltage motors to control, protect and monitor the system. The switchgear meets IEC298 and GB3906-91 standards. In addition to supporting the domestic VS1 vacuum circuit breaker, it can also be used with ABB VD4, Siemens domestic ZN65A 3AH5, GE VB2 and so on. It's really a good power distribution device.
In order to meet the requirements of wall-mounted and front-end maintenance, the switch cabinet is equipped with a special current transformer, so that the personnel can perform maintenance and inspection in front of the cabinet.
