New Flexible and Eco-Friendly Medium-Voltage Solutions: Customizable 12kV–24kV Ring Main Units Now Available
As global demand grows for reliable and sustainable power distribution equipment, Zhuhai Comking Electric Co., Ltd. has introduced an advanced series of medium-voltage switchgear designed to meet diverse grid and industrial requirements. The newly launched 12kV/17.5 kV/24kV Ring Main Unit combines operational flexibility with environmental responsibility, offering utilities and infrastructure projects a modern alternative for secondary distribution networks.
Engineered to handle rated voltages of 12kV, 17.5kV, and 24kV, this ring main unit (RMU) supports a wide range of applications, from urban compact substations to renewable energy integration points. One of its key features is the customizable 12kV ring main unit option, which allows engineers to tailor configurations—such as number of switch modules, type of fault interrupters, and enclosure dimensions—without compromising on safety or performance standards. This modular approach reduces unnecessary capacity overhead and enables cost‑effective scaling for specific project needs.
In parallel, the company has placed strong emphasis on the environmental protection switchgear aspect of the design. By utilizing recyclable materials, SF₆‑free insulation alternatives (such as solid dielectric or clean air technology), and enhanced sealing to prevent gas leakage, the RMU significantly lowers its lifecycle carbon footprint. Independent tests indicate that the unit maintains stable operation under extreme temperature and humidity variations, while its compact footprint further reduces civil works and material consumption.
All units are factory‑assembled and undergo full type tests according to IEC standards. The switchgear features integrated mechanical interlocks, visible break points, and optional remote monitoring capabilities for smart grid readiness. Zhuhai Comking Electric Co., Ltd. states that the new series is already available for order, with lead times optimized for both small‑scale retrofits and large distribution automation projects.
“We focused on delivering a solution that balances technical robustness with genuine environmental gains,” said a company spokesperson. “The 12kV/17.5 kV/24kV Ring Main Unit and its customizable variants are direct responses to market calls for greener, adaptable switchgear that doesn’t force users to over‑specify.”
The complete product range includes ratings up to 630A for busbars and feeder circuits, with short‑circuit withstand capacities suitable for most secondary substation applications.
