Switchgear & Switch Cabinets
Special Design of Outdoor Ring Main Unit Cabinet
With the development of modern industry, electrical control equipment has increasingly high requirements for automation and intelligence. Integrating modules such as power equipment monitoring, protection, and control to achieve unified management has become an inevitable trend. The HCXGW-12 outdoor high-voltage ring main unit cabinet is developed by summarizing the safe and reliable operation experience of switch-equipped branch cabinets and combining with distribution network automation technology. It integrates 12kV switchgear, power PT cabinets, feeder FTUs, etc., into a movable, sealed, and moisture-proof cabinet body, realizing the integration of primary and secondary systems and assembly modularization of urban distribution networks.

Product overview
With the Development of Modern Industry
With the development of modern industry, electrical control equipment has increasingly high requirements for automation and intelligence. Integrating modules such as power equipment monitoring, protection, and control to achieve unified management has become an inevitable trend. The HCXGW-12 outdoor high-voltage ring main unit cabinet is developed by summarizing the safe and reliable operation experience of switch-equipped branch cabinets and combining with distribution network automation technology. It integrates 12kV switchgear, power PT cabinets, feeder FTUs, etc., into a movable, sealed, and moisture-proof cabinet body, realizing the integration of primary and secondary systems and assembly modularization of urban distribution networks.
This equipment has prominent structural advantages: it is composed of fully insulated and fully sealed HCBXGN 囗 series gas-insulated switchgear and an outdoor cabinet body. The outdoor cabinet body has good corrosion resistance and anti-theft performance, with a protection level of IP43 and strong rainproof capability; the top cover adopts an air 夹层 (air-insulated) double-layer structure, and the cabinet body is equipped with excellent ventilation, heat insulation, and sealing design, which can effectively prevent moisture and dust; the switchgear inside the cabinet has completed installation and testing before leaving the factory, and only hoisting is required on-site, featuring simple installation and small floor space occupation.
