Established in 1992 as "Yueqing Shuguang Fuse Factory," Wenzhou Shuguang Fuse Co., Ltd. has evolved into a premier power technology enterprise. Located in Yueqing, the renowned "Electrical Capital of China," we stand as a beacon of research, development, and high-precision production.
For over three decades, we have integrated advanced engineering with a deep commitment to electrical safety. Our facility is more than just a factory; it is a center of excellence designated by the Ministry of Electric Power Industry to manufacture high-voltage fuses across various voltage levels, including current-limiting fuses and protection units for power capacitors and transformers.
The global transition to green energy—including solar and wind farms—requires robust circuit protection. High-voltage fuses are critical in protecting inverters and battery storage systems from catastrophic failures.
Modernization of electrical grids in Europe and North America demands fuses that meet stringent IEC and DIN standards. Reliability is paramount as utilities integrate IoT-enabled monitoring.
Electric vehicle charging stations require specialized high-speed fuses to handle rapid power surges, driving a new wave of demand for precision-engineered circuit protection.
Currently, the global industry is witnessing a surge in demand for CE Certified Fuses that guarantee safety and interoperability across international borders. From the power stations of Southeast Asia to the industrial hubs of Europe, engineers are prioritizing suppliers who can provide certified performance data and long-term durability. As a leading China factory, we stay ahead of these trends by continuously upgrading our material science and testing protocols.
Ensuring compliance with the world's most rigorous safety standards.

Our products have passed exhaustive testing at the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center and the Xi'an High-voltage Electrical Apparatus Research Institute. Technical performance meets or exceeds ANSIC37.42, DIN43625, BS2692, IEC60282-1, and VDE0636. This level of certification ensures our global partners that every fuse leaving our factory is built for "worst-case scenario" reliability.
Utilized by municipal power companies to protect transformers and underground cabling from short-circuit damage, ensuring city-wide energy stability.
Critical for steel mills and chemical plants where voltage transformer protection and high-current limiting are essential for worker safety and equipment longevity.
Specialized high-voltage fuses designed for power capacitors, preventing cascading failures in reactive power compensation systems.
Providing cost-effective drop-out fuses and lightning arresters for remote power poles and communication towers in developing regions.
As a leading China Good Fuses Supplier, Wenzhou Shuguang Fuse Co., Ltd. offers unique advantages that combine manufacturing scale with high-tech precision:
Our products are exported to various provincial power companies across China, forming a massive domestic sales network. Beyond borders, we have established strong business ties in Southeast Asia, the Middle East, Africa, and Europe. We rank consistently among the top exporters in the fuse industry due to our adherence to the principle: "Development by science and technology, and survival by quality."
We invite international procurement officers, engineers, and distributors to explore a partnership with us. Whether you need standard DIN fuses or specialized protection for modern oil-immersed transformers, our engineering team is ready to deliver. Together, we can build a safer, more reliable global power grid.
