The HXGN-12 Box Type Fixed AC Metal Closed Ring Switchgear (commonly referred to as a ring main unit) is an elite AC high-voltage complete set of electrical equipment engineered for networks with a rated voltage of 12kV and a rated frequency of 50Hz. It plays a dominant and critical role in three-phase AC ring networks, terminal distribution networks, and industrial power equipment, providing seamless acceptance and distribution of electrical energy. Due to its optimized structure, it is exceptionally well-suited for direct mounting into box-type transformer substations.
Ring Main Unit Optimization: Explicitly engineered to manage looping and grid sectionalizing tasks in high-density industrial and urban ring distribution systems.
Compact Substation Integration: Its small footprint and tailored entry design make it perfectly suitable for seamless installation inside compact box-type transformer substations.
Dual Load Switch Compatibility: Built with adaptive engineering that flawlessly supports both FN12-10 and FN25-12 load switch parameters based on specific project load currents.
Robust Assembled Protection Matrix: Incorporates heavy-duty assembled electric configurations with a maximum rated fuse current capability of 100A and up to 31.5kA short-circuit breaking current protection.
