Product Overview
The HXGN17-12 box-type fixed AC medium voltage metal-enclosed switchgear (referred to as the ring network cabinet) is a complete set of AC high-voltage electrical equipment with a rated voltage of 12kV and a rated frequency of 50Hz, and also serves as a high-performance 11 kv switchboard perfectly matching 11kV power distribution systems. This medium voltage metal-enclosed switchgear and dedicated 11 kv switchboard is mainly used for receiving and distributing electric energy in three-phase AC ring network systems, terminal power distribution, power grids, and industrial power equipment. It is also suitable for installation in switchgear cabinets within box-type substations as a compact and stable 11 kv switchboard.
For higher capacity applications, the 33kV switchgear can be integrated into the system, providing enhanced performance and reliability in handling higher voltage levels. The HXGN17-12 ring network cabinet, as a core 11 kv switchboard and essential medium voltage metal-enclosed switchgear, is a key component in modern power distribution, ensuring safe and efficient energy management within medium voltage metal-enclosed switchgear installations.
