Established in 1992 as "Yueqing Shuguang Fuse Factory," Wenzhou Shuguang Fuse Co., Ltd. has grown into a leading force in the power technology sector. Located in Yueqing, Zhejiang—famously known as the Electrical Capital of China—our company integrates high-level R&D, advanced production, and global distribution services.
For over three decades, we have focused on the development of Fault Limiting Fuses and high-voltage protection devices. Our expertise is rooted in a deep understanding of electrical safety and grid stability, allowing us to serve as a pivotal supplier for major provincial power companies across China and international partners worldwide.
As urbanization accelerates across Southeast Asia, Africa, and the Middle East, the demand for stable power grids has never been higher. Fault Limiting Fuses are essential in protecting expensive transformers from catastrophic short-circuit currents.
The global shift toward wind and solar energy requires smarter grid protection. Our current-limiting fuses are designed to handle the rapid fluctuations and high DC/AC loads associated with modern renewable energy substations.
In Europe and North America, aging power infrastructure is being replaced. There is a massive procurement need for DIN-standard and IEC-compliant HRC fuses to ensure seamless backward compatibility with existing systems.
Our commitment to quality is backed by rigorous testing and international certifications. Wenzhou Shuguang Fuse products are designated by the Ministry of Electric Power Industry for high-voltage protection.
Our protection solutions are versatile, addressing the specific needs of diverse environments, from heavy industrial zones to remote rural grids.
Specially designed H.V. HRC Fuses for back-up protection in oil-immersed transformers, preventing internal faults from causing external grid failure.
Miniature fuse links and current-limiting devices tailored for compact 10kV to 36kV switchgear used in densely populated city centers.
High-reliability capacitor protection fuses designed to handle harmonic currents and transient overvoltages in power factor correction systems.
Customized fuse solutions for wind turbine nacelles and solar inverter stations, offering rugged performance against environmental stress.
As a leading China Fault Limiting Fuses Factory, we offer more than just products; we offer a strategic partnership characterized by:
The "Shu Rong" brand has achieved a high reputation among users worldwide. We have formed a complete sales network that bridges Chinese manufacturing excellence with global procurement needs.
Supplying various provincial power companies across China, ranking among the top in the industry for domestic sales and reliability.
Exporting to Southeast Asia, the Middle East, Africa, and Europe, adapting to localized standards like BS (British) and VDE (German).
As the electric power industry evolves with smart grid technologies and increased demand for energy efficiency, the role of reliable China Fault Limiting Fuses becomes even more critical. Wenzhou Shuguang Fuse Co., Ltd. remains committed to the principle of "Development by science and technology, and survival by quality." We sincerely welcome global procurement managers, electrical engineers, and industrial wholesalers to discuss long-term cooperation. Our factory is equipped to handle the most demanding technical specifications, ensuring that your electrical infrastructure is protected by components that represent the pinnacle of Chinese engineering excellence.
