Dehler
As the global energy landscape transitions from fossil fuels to sustainable sources, the role of the Ring Main Unit (RMU) has evolved from a simple distribution point to a critical node of intelligence and protection. In Photovoltaic (PV) and Wind Power applications, RMUs are the frontline of grid stability.
Unlike traditional urban distribution, Renewable Energy RMUs (PV/Wind) must withstand harsh environmental conditions—from the high UV and heat of solar deserts to the corrosive salt-mist of offshore wind farms. High-quality RMU factories today focus on SF6-free gas insulation, digital monitoring, and modular designs that allow for rapid scaling of green energy projects.
Dehler Technology integrates Information Gain into every product, providing not just hardware, but data-driven safety features that ensure a 30-year operational lifespan for renewable infrastructure.
Established in 2016 and headquartered in the electrical hub of Yueqing City, Dehler Technology Co., Ltd. has rapidly emerged as a powerhouse in the high and low voltage power equipment industry. Our facility at No. 271, Weishiqi Road, and our specialized transformer division at No. 178, Jingba Road, represent the pinnacle of Chinese electrical engineering.
We are a technology enterprise integrating R&D, production, sales, and service. Our expertise spans:
Our commitment to "Survival through quality, development through technology" has made us a trusted partner for global power generation and industrial automation sectors.
Located in Yueqing, the "Electrical Capital of China," we benefit from a complete upstream and downstream supply chain. This reduces lead times and allows for custom engineering at scale.
Mass production capabilities and optimized logistics ensure that our Renewable Energy RMUs offer the highest ROI compared to European or American manufacturers without sacrificing quality.
Chinese factories are at the forefront of "Smart Grids." We iterate technology faster, integrating IoT sensors and remote monitoring into RMUs more efficiently than traditional competitors.
For global enterprises, procuring RMUs isn't just about the hardware; it’s about meeting regional regulations and ensuring site-specific performance.
All our products, including the XGN15-24 and KYN61-40.5 series, are designed and tested according to IEC 62271 standards, ensuring seamless integration into grids in Europe, Asia, and South America.
We provide localized versions of RMUs with IP67 ratings for flood-prone areas, C5-M anti-corrosion coating for offshore wind farms, and enhanced ventilation for high-temperature PV stations in MENA regions.
Dehler provides comprehensive documentation, remote technical support, and partnership programs with local installers to ensure that your equipment is commissioned and maintained to factory standards.
Our compact RMUs are ideal for urban rooftop solar where space is a premium. They provide the necessary protection and isolation for injecting solar power into the 10kV-35kV city grid.
The HXGN-40.5 series is engineered for the high-capacity demands of modern turbines, offering robust vacuum switching technology that handles frequent operations common in wind power variance.
As charging demand spikes, our RMUs manage the high-load distribution required for Mega-Watt scale charging hubs, ensuring grid stability and fire safety.
The next decade of power distribution is being defined by three major shifts:
The transition from SF6 gas (a potent greenhouse gas) to Air-Insulated or Alternative Gas RMUs is accelerating globally.
RMUs are becoming "IoT-enabled," providing real-time data on temperature, humidity, and contact wear to enable predictive maintenance.
Plug-and-play RMU designs allow developers to expand solar fields without replacing the entire switchgear system.
Renewable Energy RMUs are designed for frequent switching cycles and extreme environments. In wind/solar, the load is intermittent, requiring circuit breakers with higher mechanical endurance. Additionally, they often operate at 33kV/36kV/40.5kV to match collector system voltages.
Yes. We specialize in custom-engineered switchgear tailored to specific grid requirements, including non-standard dimensions for compact substations and specific protection relay integration (e.g., ABB, Schneider, or Siemens relays).
We adhere to ISO 9001 management systems and national quality standards. Every RMU undergoes rigorous factory acceptance testing (FAT), including dielectric tests, partial discharge monitoring, and mechanical operation tests before shipping.
Typical lead times range from 4 to 8 weeks depending on the complexity of the customization, leveraging our Yueqing supply chain to ensure speed without compromising reliability.
