HHWX-12 Series High Voltage Ring Main Box (Outdoor Switching Station)

HHWX-12 Outdoor Switching Station, as a new generation of automated power distribution equipment, it is developed to meet the practical development needs of power system distribution network automation. It integrates full functions including system monitoring, system control, and system communication—fully satisfying all requirements of distribution network automation—making it an ideal modern outdoor switching device. The enclosure is made of 2.0mm stainless steel or polystyrene panels, with a reasonable cabinet structure: each compact functional unit has independent space, separated by partitions to avoid mutual interference. The inner cabinet can be equipped with HXGN-type ring main units (RMUs) and a “five-proof interlocking” mechanism to prevent misoperation and unauthorized operation. The cabinet surface can be polished or painted according to user requirements. The top cover adopts an air-insulated double-layer structure with ventilation openings: air inlets are located at the lower part of the cabinet, and air outlets are installed at the top, hidden under the roof eave to form bottom-up air convection. This design ensures excellent heat insulation and ventilation performance.
