Explore our high-performance oil fuses and current-limiting solutions engineered for global power grids.
Established in 1992 as "Yueqing Shuguang Fuse Factory," we have grown into a leading China OEM Oil Fuse Supplier. Located in Yueqing, Zhejiang Province—the renowned "Electrical Capital of China"—our company serves as a high-tech powerhouse integrating R&D, manufacturing, and global distribution.
With over three decades of specialized experience, we represent the pinnacle of Chinese electrical engineering, providing critical protection for transformers and power systems across six continents. Our "Shu Rong" brand is synonymous with reliability and technical excellence.
As the world transitions toward smarter grids and renewable energy, the demand for high-reliability Oil Fuses has reached unprecedented levels.
The global oil fuse market is expanding rapidly due to infrastructure modernization in North America and rapid urbanization in Asia. OEM partnerships with Chinese factories are critical for maintaining supply chain resilience.
Modern Oil Fuses are now designed to withstand the harmonic fluctuations caused by wind and solar integration, ensuring that localized transformers remain protected during peak renewable surge periods.
Global procurement standards are shifting toward fuses that offer higher breaking capacities and better environmental resistance, especially in harsh coastal or desert climates.
Our commitment to excellence is validated by rigorous testing and international certification compliance.
Our products are designated by the Ministry of Electric Power Industry. We manufacture high-voltage fuses, zinc oxide arresters, and insulators that pass through the most stringent high-power test stations in China, including the Xi'an High-voltage Electrical Apparatus Research Institute.
Our technical performance meets and exceeds international standards including ANSI C37.42, DIN 43625, BS 2692, IEC 60282-1, and VDE 0636. This ensures our oil fuses are compatible with global transformer specifications from Europe to the Americas.
Every "Shu Rong" brand product undergoes comprehensive performance testing. Our quality assurance system is complete, ensuring that every HRC current-limiting fuse provides the backup protection required for oil-immersed transformers.
From high-density urban substations in London to solar farms in the Australian Outback, Oil-Immersed Fuses are the silent guardians of the grid. As a leading factory, we understand that "one size fits all" does not apply to electrical safety.
