This integrated outdoor ring network cabinet is tailor-made for China’s urban and rural power distribution grid scenarios, representing the domestic advanced technical level of outdoor power distribution equipment. It integrates pre-installed and pre-tested 12kV switchgear, power PT cabinet, feeder FTU/RTU, communication control terminal, metering & automatic meter reading module, and UPS power supply into a movable, fully sealed, moisture-proof stainless steel or non-metallic enclosure, realizing the integration of primary and secondary systems and modular assembly of urban distribution networks, while greatly shortening on-site construction cycles.
The HCXGW-12 outdoor ring network cabinet follows a clear and standardized coding system: HC (Huachen) - XGW (Outdoor Ring Network Cabinet) - 12 (Rated Voltage 12kV), enabling fast parameter confirmation and project matching for engineering and procurement teams.
This pre-assembled outdoor power distribution cabinet adopts a highly integrated modular design, with standard configurable units covering all core functions of outdoor distribution:
12kV High Voltage Switchgear Unit: Core power distribution switching module
Power PT Unit: Voltage measurement and power supply module for auxiliary systems
Feeder Automation Unit: FTU/RTU terminal for distribution network monitoring and control
Communication & Control Terminal: Remote data transmission and grid automation interaction module
Metering & Automatic Meter Reading Unit: Precision power metering and remote data upload module
UPS Power Supply Unit: Uninterrupted power supply for automation and control systems
This weatherproof outdoor ring network box features a fully sealed, moisture-proof, and corrosion-resistant enclosure, with optional stainless steel or high-performance non-metallic composite materials to adapt to long-term outdoor operation under various climatic conditions. The factory pre-assembled and pre-tested design eliminates complex on-site assembly and debugging, minimizing on-site construction difficulty and human error risks.
For municipal power grid construction departments, outdoor distribution project integrators, and engineering contractors, the integrated modular design cuts on-site construction period by more than 60%, while the pre-tested system ensures one-time power-on success. The built-in full-set distribution automation modules support remote monitoring and control, realizing intelligent operation and maintenance of the distribution network, and significantly reducing on-site O&M costs.

Relevant national and industry standards for urban distribution network automation and outdoor power distribution equipment
This intelligent outdoor distribution ring network cabinet is the core equipment for urban and rural power distribution network construction and transformation, widely used in urban distribution network upgrading projects, municipal engineering, industrial park outdoor power distribution, residential area power supply facilities, rural power grid upgrading projects, roadside distribution stations, and temporary power supply projects for large-scale construction sites. It is the preferred solution for power grid construction departments, municipal engineering contractors, and outdoor power distribution project integrators.
Yes. All functional units are fully assembled, wired, and rigorously tested in the factory before delivery. Only simple on-site cable connection is required, which greatly shortens the construction period and reduces on-site debugging work.
We offer two mainstream enclosure material options: high-quality 304/316 stainless steel and high-performance non-metallic composite materials, both with excellent moisture-proof, corrosion-resistant, and weather-resistant properties for long-term outdoor operation.
Yes. The standard configuration integrates FTU/RTU feeder automation terminals, communication control modules, and automatic meter reading units, which are fully compatible with urban distribution network automation systems, supporting remote monitoring, control, and fault handling.
