Established in 1992 as the "Yueqing Shuguang Fuse Factory," we have grown into a premier power technology enterprise. Located in Yueqing, Zhejiang—the renowned Electrical Capital of China—our company integrates advanced R&D, sophisticated production, and global sales service.
With over three decades of deep industry experience, we specialize in high-voltage current-limiting fuses and power capacitor protection. Our commitment to innovation and quality has made us a cornerstone of the Chinese electrical manufacturing landscape.
Contact Us TodayAnalyzing the shift in global power protection and procurement needs.
The global shift toward Solar and Wind energy requires high-current fuses capable of handling DC circuits and variable loads. We are at the forefront of this transition, providing specialized protection for green energy infrastructures.
Electric Vehicle (EV) charging stations and battery protection systems demand ultra-fast acting high current fuses. Our R&D team continuously develops EV-specific fuses that meet rigorous automotive safety standards.
Modern power grids are becoming "smarter" and more interconnected. This requires intelligent fuse systems that offer not only circuit protection but also reliability in high-density urban power distribution networks.
Our products are designated by the Ministry of Electric Power Industry. We adhere to the highest international standards including ANSI C37.42, DIN 43625, BS 2692, IEC 60282, and VDE 0636. Every component undergoes rigorous testing at the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center.
International procurement managers today face the challenge of balancing cost with extreme reliability. As a China-based manufacturer, we provide the perfect equilibrium by leveraging the local industrial cluster in Yueqing.
Our "Shu Rong" brand is recognized worldwide for its "Survival by Quality" philosophy, ensuring that our localized applications meet the specific environmental and regulatory demands of each region.
Being in the "Electrical Capital," we have immediate access to high-quality raw materials and specialized sub-components, reducing lead times and costs.
Unlike rigid Western manufacturers, we offer agile R&D. We can customize high-voltage fuses based on specific client technical parameters within weeks.
Whether you need a prototype or a thousand units for a provincial grid project, our facilities are equipped to scale without compromising quality.
