In the evolving landscape of global energy distribution, the Solid Insulated Ring Main Unit (SIR RMU) represents a critical technological leap. As international regulations tighten around the use of SF6 gas—a potent greenhouse gas—industry leaders are pivoting toward solid insulation technology. Our SIR RMU systems utilize advanced epoxy resin embedding technology, completely eliminating the risk of gas leakage while providing superior dielectric strength.
This white paper explores how Dehler Technology is spearheading this transition, combining China Factory 4.0 efficiency with world-class engineering to deliver RMUs that are not only environmentally responsible but also resilient in the most extreme operating conditions, from coastal high-humidity areas to high-altitude mountain grids.
Dehler Technology Co., Ltd., established in 2016, is a premier technology enterprise specializing in R&D, production, sales, and service within the high and low voltage power equipment industry. Headquartered in Yueqing City, the heart of China's electrical manufacturing, we operate specialized divisions for switchgear and transformers.
Our commitment to "survival through quality, development through technology" is evidenced by our comprehensive marketing network and after-sales service system. We serve critical sectors including railway electrification, steel mills, wind power generation, and petroleum industries. Our products meet the diverse needs of modern power systems with precision and reliability.
We leverage a systematic and standardized quality management system as a strong foundation. Strictly adhering to national and international quality standards, we have earned widespread acclaim for our diversified product offerings and impeccable service. We don't just sell products; we cultivate long-term, stable partnerships through trust and technical transparency.
The next generation of SIR RMUs will feature Thermoplastic Elastomers (TPE) and advanced composite resins. These materials offer better recyclability and even higher thermal conductivity, allowing for more compact designs without compromising current-carrying capacity.
We are integrating fiber-optic temperature sensing and online partial discharge monitoring into our RMU core. This allows for predictive maintenance, where the unit communicates its "health status" to a cloud-based digital twin, reducing unplanned outages by up to 40%.
By 2030, the global grid must transition away from SF6. Dehler’s roadmap ensures that our Solid Insulated solutions are compatible with green hydrogen production plants and massive-scale EV charging hubs, supporting the Net-Zero transition.
Dehler’s manufacturing facility at No. 271, Weishiqi Road is a model of Smart Manufacturing. By implementing Factory 4.0 principles, we ensure that every SIR RMU produced meets the highest precision standards. Our automated casting lines for epoxy resin components ensure a void-free insulation structure, which is critical for preventing partial discharge at high voltages.
Efficiency Advantages: Through localized vertical integration, we control the entire process from the raw contact materials (like our high-quality plum blossom contacts) to the final assembly of the RMU. This reduces lead times by 30% compared to traditional manufacturers and ensures 100% traceability of components.
Our compact SIR RMUs are designed for underground installation in high-density urban areas. Their maintenance-free nature and SF6-free design make them safe for public spaces and confined basements.
Providing reliable switching for wind and solar farms. Our RMUs handle the frequent switching operations and harmonic challenges common in renewable energy integration with ease.
For steel mills and mining operations, the SIR RMU offers unmatched protection against dust, moisture, and chemical corrosion, ensuring continuous operation in harsh environments.
For international EPC contractors and utility providers, the procurement of RMUs involves more than just price. It requires a partner who understands Total Cost of Ownership (TCO) and Operational Resilience.
Modular designs that can be configured for 2-way, 3-way, or 4-way configurations with ease.
Full adherence to IEC 62271-200 standards and local grid codes across Europe, SE Asia, and the Middle East.
Strategic proximity to major ports like Ningbo/Shanghai ensures rapid global deployment.
24/7 technical hotline and on-site training for local engineering teams.
“High-quality products, superior technology, and impeccable service" are the goals pursued by Dehler. Facing the opportunities and challenges of international industrial electrical development, we have formulated a new development strategy and rapidly established a systematic, large-scale production model.
Based in China, with a global perspective, our company, based on the principle of mutual benefit, sincerely collaborates with friends from all walks of life. We welcome all parties to visit and inquire!
