Established in 1992 as "Yueqing Shuguang Fuse Factory," Wenzhou Shuguang Fuse Co., Ltd. has evolved into a titan of power technology. Located in Yueqing, Zhejiang Province—the renowned "Electrical Capital of China"—we integrate advanced research, development, production, and global service.
With over three decades of manufacturing experience, we are designated by the Ministry of Electric Power Industry to produce critical high-voltage components. Our commitment to the "Survival by Quality" principle ensures every Oilfuse-link and high-voltage cutout meets the most rigorous industrial demands.
In the modern electrical grid, oil-immersed fuse links (Oilfuse-links) are indispensable for protecting transformers and distribution networks. As global energy consumption rises, the demand for reliable circuit protection in oil-filled switchgear has reached an all-time high. These components are critical for preventing catastrophic failures in both urban and rural power infrastructures.
The industry is moving toward "Smart Grids" and higher voltage stabilization. There is a significant trend in the development of current-limiting fuses that offer faster response times and higher breaking capacities. Furthermore, the integration of renewable energy sources (solar/wind) requires specialized oil-fuse links that can handle fluctuating loads and environmental stressors.
Global utility companies and industrial EPC contractors are increasingly seeking manufacturers who can provide a "one-stop-shop" for HV protection. Key procurement factors now include IEC/DIN certification compliance, long-term durability in mineral oils, and the ability to customize fuse characteristics for specific transformer profiles.
At Shuguang, we utilize high-quality raw materials and sophisticated testing equipment as the backbone of our quality assurance system. Every Oilfuse-link is engineered to meet IEC60282-1 and DIN43625 standards.
Our R&D focus is on the thermal stability of the fuse element and the sealing integrity of the fuse body, ensuring zero leakage and consistent performance within transformer oil environments.
