Established in 1992 as "Yueqing Shuguang Fuse Factory," Wenzhou Shuguang Fuse Co., Ltd. has evolved into a leading power technology enterprise. Located in the electrical capital of China—Yueqing, Zhejiang Province—we integrate research, development, production, and sales into a seamless service for the global power grid.
For over three decades, we have been a designated manufacturer for the Ministry of Electric Power Industry, specializing in high-voltage current-limiting fuses, power capacitor fuses, and zinc oxide arresters. Our brand, "Shu Rong," is synonymous with uncompromising safety and technical excellence across international borders.
In the high-stakes world of industrial electrical protection, CE Certification is not just a label—it is a guarantee of safety, performance, and compliance with European Union standards that are respected globally. Our products undergo rigorous testing at the highest-level domestic and international laboratories, including the Electric Power Research Institute and the Xi'an High-voltage Electrical Apparatus Research Institute.
Our fuses meet the technical performance requirements of ANSI C37.42, DIN 43625, BS 2692, and IEC 60282-1. This ensures compatibility with diverse power grids from Europe to North America.
Products are validated through high-power test stations, ensuring the breaking capacity, temperature rise, and mechanical durability exceed GB15166 and VDE0636 standards.
With ISO 9001:2000 certification, our quality assurance system tracks every raw material and production process, making us a trusted partner for national power companies worldwide.
The global electrical industry is undergoing a paradigm shift towards Smart Grids and Renewable Energy Integration. CE standard fuses are now required to handle higher DC voltages for solar PV systems and provide ultra-fast protection for Electric Vehicle (EV) charging infrastructure. We are at the forefront of this trend, developing current-limiting fuses that minimize thermal damage during short-circuit events.
Global procurement managers are increasingly looking for cost-effective yet compliant suppliers from China. The demand focuses on "Ready-to-Install" solutions that reduce local assembly time. Buyers prioritize manufacturers like Shuguang who can provide full technical documentation and certification for European and Middle Eastern utility tenders.
In local scenarios, such as heavy industrial plants in Southeast Asia or residential substations in Europe, the environmental adaptability of a fuse is critical. Our products are designed with high-grade porcelain and polymer materials to resist UV degradation and corrosive industrial atmospheres, ensuring a service life of over 20 years.
Partnering with a specialized factory in Yueqing offers several strategic advantages for global distributors and EPC contractors:
Innovation at Wenzhou Shuguang Fuse Co., Ltd. is driven by the principle: "Development by science and technology, and survival by quality." We have invested heavily in automated winding machines for high-voltage elements and precision filling stations for arc-extinguishing quartz sand.
Our technical team focus on the Current-Limiting capability of our DIN standard fuses. By optimizing the fuse element geometry, we ensure that fault currents are interrupted in the first half-cycle, significantly protecting downstream equipment like transformers and switchgear from mechanical stress.
From provincial power companies across China to infrastructure projects in Southeast Asia, the Middle East, and Europe, our "Shu Rong" brand fuses are trusted where reliability cannot be compromised.
