Ensuring stability across global electrical grids with advanced fuse technology.
Established in 1992 as "Yueqing Shuguang Fuse Factory," Wenzhou Shuguang Fuse Co., Ltd. has evolved into a global powerhouse in electrical protection technology. Located in Yueqing, Zhejiang—the renowned "Electrical Capital of China"—we integrate advanced R&D, sophisticated manufacturing, and global service protocols to deliver high-quality ChinaOilFuse solutions.
For over three decades, we have remained committed to the principle of "Development by science and technology, and survival by quality." Our deep-rooted expertise allows us to serve the most demanding environments, ensuring that power transformer units and distribution networks operate with maximum safety and efficiency.
Adapting to the energy transition with reliable protection systems.
Global demand for oil-immersed fuse-links is surging due to the expansion of smart grids and the need for reliable protection in oil-filled transformer tanks. As infrastructure ages, utilities are replacing traditional systems with modern, standard-compliant HRC fuses.
With the rise of wind and solar farms, medium voltage protection is critical. Oil fuses provide the necessary thermal stability and high breaking capacity to protect expensive capacitor banks and distribution equipment in remote locations.
Global enterprises are shifting toward consolidated procurement from Chinese factories that offer OEM/ODM customization and compliance with international standards like IEC, DIN, and BS, balancing performance with cost-efficiency.
Our products are engineered to meet and exceed global technical specifications.
Wenzhou Shuguang Fuse Co., Ltd. is designated by the Ministry of Electric Power Industry. Our ChinaOilFuse links and high-voltage products have passed rigorous testing at the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center and the Xi'an High-voltage Electrical Apparatus Research Institute.
Harnessing the power of the world's most advanced electrical supply chain.
As a leading Chinese factory, we utilize sophisticated testing equipment and high-quality raw materials to ensure every fuse-link meets stringent performance indicators.
We provide tailored solutions for specific voltage levels and environmental conditions. Whether it's a unique J-slotted fuse or a specific 63A oil fuse-link, we can customize production to user needs.
Located in the electrical capital, we have immediate access to specialized logistics and high-grade components, allowing for faster turnaround times compared to western counterparts.
Our "Shu Rong" brand products are exported to Southeast Asia, the Middle East, Africa, and Europe, ranking consistently at the top of the industry for domestic and international sales.
