Founded in 1992 as "Yueqing Shuguang Fuse Factory," Wenzhou Shuguang Fuse Co., Ltd. has evolved into a powerhouse of electrical technology. Situated in Yueqing, Zhejiang—the renowned "Electrical Capital of China"—we represent the pinnacle of Chinese engineering in power protection. As an integrated enterprise, we specialize in the research, development, and mass production of advanced fuse systems that safeguard critical infrastructure worldwide.
Our journey over the past 30 years has been defined by a commitment to the E-E-A-T principles. We don't just manufacture; we provide peace of mind through rigorous testing and adherence to international quality standards. With a complete scientific management system, we have transitioned from a local workshop to a global leader, supplying provincial power companies in China and international partners across five continents.
The global shift toward solar and wind energy has created an urgent demand for high-voltage current-limiting fuses. Our products are optimized for the fluctuating loads and unique DC/AC requirements of modern green energy grids, ensuring that the transition to sustainable power is safe and reliable.
As the automotive industry electrifies, specialized EV fuses have become critical. We have pioneered compact, high-performance fuses designed specifically for charging stations and onboard battery management systems, meeting the rigorous vibration and temperature standards of the EV sector.
Modern power grids require components that offer consistent performance and longevity. Our high-voltage current-limiting fuses and XRNP series are engineered for the precision required by smart monitoring systems, reducing downtime and maintenance costs for global utility providers.
Our authority is backed by the Ministry of Electric Power Industry, which has designated us as a key producer of high-voltage fuses across various voltage levels. We maintain a robust quality assurance system certified by ISO9001:2000. Every product leaving our factory has passed rigorous evaluations at the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center and the Xi'an High-voltage Electrical Apparatus Research Institute.
Compliance with International Standards:
International industrial buyers require high-volume consistency. Our factory-direct model eliminates middlemen, offering competitive pricing for high-voltage HRC fuses while maintaining the "Shu Rong" brand reputation for reliability. We handle complex logistics to Southeast Asia, the Middle East, and Europe.
We understand that every regional grid has unique specifications. From 11kv expulsion fuse links for tropical climates to oil-immersed transformer protection for heavy industrial zones, our R&D team can customize electrical performance indicators to meet specific localized user needs.
Our drop-out fuse cut outs and zinc oxide arresters are deployed in diverse environments—from high-density smart cities in Europe to rural electrification projects in Africa. Our products are engineered to withstand extreme weather and deliver stable power distribution everywhere.
