In the evolving landscape of medium-voltage power distribution, the Air-Insulated Ring Main Unit (AIS RMU) has emerged as a critical technology for modern grid infrastructure. Unlike Gas-Insulated Switchgear (GIS) which often relies on SF6—a potent greenhouse gas—AIS RMU utilizes ambient air as the primary insulating medium. As global regulations tighten around carbon emissions and environmental sustainability, AIS RMUs represent the "Green Path" for utilities and industrial power users.
Custom AIS RMU solutions are increasingly sought after because power grids vary significantly by region. Whether it's accommodating the fluctuating output of a wind farm in Northern Europe or meeting the compact footprint requirements of a dense urban substation in Southeast Asia, customization is no longer an option—it’s a necessity for operational excellence.
The global AIS RMU market is witnessing a CAGR of over 6% as aging infrastructure in developed nations is replaced with smart-ready, eco-friendly equipment. China has become the global hub for RMU manufacturing, offering a balance of high-tech R&D and cost-efficient production scales.
Digitalization is the foremost trend. Modern AIS RMUs are now equipped with IoT sensors for temperature monitoring, partial discharge detection, and vacuum integrity analysis. This shifts maintenance from reactive to predictive, saving millions in potential downtime.
From secondary distribution in municipal grids to specialized applications in mining and high-speed rail, AIS RMUs are valued for their ease of maintenance and long service life. In coastal areas, our units are customized with anti-corrosive coatings to withstand saline environments.
Established in 2016, Dehler Technology Co., Ltd. is a premier technology enterprise based in Yueqing City, specializing in the R&D, production, and service of high and low voltage power equipment. Our facilities, located in the Yanpan Economic Development Zone, produce a comprehensive range of switchgear, prefabricated substations, and vacuum circuit breakers.
We operate under the philosophy of "Survival through quality, development through technology, and efficiency through management." Our marketing network covers key sectors including railway electrification, steel mills, wind power generation, and shipbuilding, providing reliable, energy-saving intelligent power distribution products globally.
We leverage a systematic and standardized quality management system (ISO standards) to advance our capabilities. Our long-term partnerships with global suppliers ensure a stable supply chain and cutting-edge component integration.
“High-quality products, superior technology, and impeccable service” are our core pillars. We have transitioned to large-scale production models to meet the challenges of international industrial electrical development while maintaining artisanal attention to detail.
Focus on modular design, arc-flash safety, and mechanical reliability. Current AIS RMUs utilize high-grade epoxy resin insulators and optimized busbar configurations to minimize footprint while maximizing air-clearance safety.
Integration of intelligent electronic devices (IEDs) and communication protocols (IEC 61850). This allows RMUs to communicate with SCADA systems, enabling remote switching and real-time load management, essential for modern Smart Grids.
Development of 100% recyclable materials and AI-driven autonomous grid self-healing. Future RMUs will not only distribute power but also act as data hubs for the entire distribution network, optimizing energy flow and reducing line losses automatically.
Custom AIS RMUs designed specifically for the high-frequency switching and variable loads of solar and wind farms.
Compact designs for metropolitan substations where space is at a premium but safety cannot be compromised.
Ruggedized switchgear for mining and steel manufacturing, capable of operating in dusty, high-vibration environments.
Specially treated AIS RMUs with high salt-spray resistance for shipborne and offshore platform applications.
Based in China with a global perspective, Dehler Technology is ready to collaborate on your next power infrastructure project. Whether you need custom switchgear or specialized high-voltage components, our team of engineers is here to provide solutions based on mutual benefit and technical excellence.
