Wenzhou Shuguang Fuse Co., Ltd. is located in Yueqing, Zhejiang Province, the electrical capital of China. We are a premier power technology enterprise integrating research, development, production, sales, and service. Our journey began as "Yueqing Shuguang Fuse Factory" back in 1992, establishing over three decades of excellence in electrical protection.
As a leading China BritishStandardFuses manufacturer, we have evolved with the global industry, specializing in high-voltage fuses of various voltage levels, current-limiting fuses, and specialized protection for power capacitors and voltage transformers. Our commitment to innovation has positioned us as a core supplier for national and international power grids.
British Standard (BS) fuses, specifically those adhering to BS 2692 and IEC 60282, remain the cornerstone of electrical safety in Commonwealth nations, the Middle East, and Southeast Asia. Their rigorous design requirements for breaking capacity and thermal stability make them indispensable for medium and high-voltage applications.
With the global push for infrastructure modernization, there is a surging demand for reliable HRC (High Rupturing Capacity) fuses. Utility companies in Europe and Africa are increasingly sourcing from China to balance high-tech performance with cost-efficiency.
The industry is shifting toward "Smart Protection." Modern fuses are now being integrated with sensor technologies to monitor thermal load. Our R&D team is actively working on the next generation of fuses compatible with digital substation environments.
Whether it is oil-immersed transformers in humid tropical climates or outdoor switchgear in arid desert regions, our fuses are designed to withstand extreme localized environmental stressors while providing millisecond-level fault isolation.
Years of Expertise
Quality Certified
Export Countries
Tested Quality
As a dedicated China BritishStandardFuses factory, we offer more than just products; we offer engineered solutions. Our advantage lies in our Integrated Supply Chain, which allows us to source high-purity silver for fuse elements and high-grade alumina ceramics for bodies at a competitive scale. Unlike trading companies, we provide direct technical support, OEM customization, and comprehensive test reports for every batch.
Our products are designated by the Ministry of Electric Power Industry. All performance tests are qualified through the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center and Xi'an High-voltage Electrical Apparatus Research Institute.
Highest Technical Compliance:
The company continues to deepen and improve the quality management system. While vigorously developing new products, we have always attached importance to the process flow. High-quality raw materials and sophisticated testing equipment are the backing of our quality assurance system. All performance indicators are in line with the corresponding technical conditions, and new products can be customized and produced at any time according to user needs.
Our "Shu Rong" brand products have enjoyed a high reputation among domestic and foreign users for their reliability in protecting critical power assets.
Our products are exported to various provincial power companies in China. A complete sales network has been formed throughout the country. Internationally, our high-voltage fuses are exported to Southeast Asia, the Middle East, Africa, Europe, and other countries and regions, ranking among the top in the industry for export volume.
The role of a China BritishStandardFuses manufacturer in today's interconnected power grid is more critical than ever. As electrical demand grows, so does the risk of high-magnitude faults. Our HRC fuses are engineered with high-grade ceramic bodies and precision-wound silver elements to ensure they break the circuit exactly when needed, preventing catastrophic transformer failure or grid downtime.
By adhering to BS 2692, we ensure that our fuses are compatible with a wide range of heritage and modern equipment found in the UK and overseas. Our factory in Wenzhou leverages the latest in AI-assisted quality control to scan for micro-fractures in ceramic components, ensuring that every unit leaving our facility meets the E-E-A-T principles of expertise and reliability.
Procurement officers and engineers worldwide are moving away from generic protection components toward specialized solutions. Whether you require medium voltage back-up protection for oil-immersed transformers or current-limiting fuses for voltage transformer protection, Wenzhou Shuguang Fuse Co., Ltd. provides the technical depth and manufacturing capacity to meet your most stringent requirements.
We invite global partners to discuss long-term cooperation. Our mission remains "Development by science and technology, and survival by quality." As we look toward the future, we continue to innovate in materials science and electrical engineering to keep the world's power flowing safely.
