Wenzhou Shuguang Fuse Co., Ltd., located in the "Electrical Capital of China" — Yueqing, Zhejiang, stands as a beacon of excellence in the power technology industry. Since our inception as the "Yueqing Shuguang Fuse Factory" in 1992, we have dedicated over three decades to the research, development, and production of high-performance electrical protection equipment.
As a specialized China ODM Dropout Fuse manufacturer, we integrate advanced manufacturing processes with a commitment to service. Our journey from a local factory to a global supplier is built on the foundation of technical integrity and a deep understanding of the global power infrastructure's evolving needs.
The global power sector is shifting towards "Smart Grids." Modern dropout fuses are no longer just passive components; they are increasingly required to provide higher breaking capacities, better environmental resilience (especially against UV and high salinity), and compatibility with automated monitoring systems.
In developing regions across Southeast Asia, Africa, and South America, massive grid expansion is driving the demand for cost-effective yet high-quality expulsion fuses. Meanwhile, in Europe and North America, the focus is on the retrofitting of aging infrastructure with more reliable polymer-insulated solutions.
Global utility companies and industrial contractors are seeking partners who can offer ODM (Original Design Manufacturer) capabilities. The ability to customize dimensions, materials, and technical specifications according to local grid standards is the primary differentiator for modern suppliers.
Our commitment to reliability is backed by rigorous testing and adherence to the world's most stringent electrical standards. We don't just manufacture; we engineer safety.
We are designated by the Ministry of Electric Power Industry to produce high-voltage fuses of various voltage levels. Our product portfolio includes high-voltage current-limiting fuses, power capacitor fuses, zinc oxide arresters, and drop-out fuses.
Every product undergoes extensive validation at the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center and the Xi'an High-voltage Electrical Apparatus Research Institute.
Our Polymeric Insulator dropout fuses are specifically designed to resist salt-spray corrosion and chemical degradation, ensuring longevity in coastal substation applications.
In expansive rural networks, reliability and ease of maintenance are paramount. Our dropout fuses provide clear visual indication of fault interruption, allowing for quick restoration of service by local technicians.
With the rise of solar and wind farms, the need for specialized H.R.C. (High Rupturing Capacity) fuses has skyrocketed. We provide custom protection for transformers and capacitor banks used in renewable energy collection systems.
Unlike many trading companies, we are a tech-integrated enterprise. We continuously invest in process flow optimization and sophisticated testing equipment to guarantee every batch of "Shu Rong" brand products meets elite standards.
Located in the heart of China's electrical hub, we benefit from a complete supply chain. This allows us to offer competitive wholesale pricing without compromising on material quality or safety performance.
Whether it's a specific voltage level for a Middle Eastern grid or a specialized mounting bracket for an African utility project, our engineering team can produce customized solutions in record time.
Our products have formed a complete sales network across every province in China. Internationally, our high-voltage current-limiting fuses and dropout fuses are exported to Southeast Asia, the Middle East, Africa, and Europe.
We operate on the principle: "Development by science and technology, and survival by quality." We invite global partners to join us in securing the future of the electric power industry.
