Industrial-grade fuses designed for stability, safety, and global standards compliance.
Located in Yueqing, Zhejiang Province, the recognized "Electrical Capital of China," Wenzhou Shuguang Fuse Co., Ltd. is a pioneering power technology enterprise. We specialize in the integrated research, development, production, and global distribution of high-performance electricity fuses.
Our journey began in 1992 as "Yueqing Shuguang Fuse Factory." Over three decades, we have evolved from a local workshop into a sophisticated manufacturing hub. Our expertise lies in ODM (Original Design Manufacturing), where we tailor electrical protection solutions to meet the specific voltage and environmental requirements of our global partners.
Understanding the vital role of circuit protection in a connected world.
The global electricity fuse market is experiencing a significant surge, driven by the rapid modernization of power grids and the explosive growth of Electric Vehicle (EV) infrastructure. As industries shift towards high-automation and digital control, the need for reliable, fast-acting current-limiting fuses has never been greater.
With the worldwide transition to renewable energy sources like solar and wind, the volatility of power inputs requires smarter, more resilient protection components. ODM manufacturers in China are at the forefront, developing specialized fuses that can withstand the unique harmonics and DC-arc challenges found in green energy systems.
Miniaturization and high breaking capacity are the two dominant technical trends. Modern industrial setups require fuses that occupy less space within switchgear cabinets while maintaining the ability to interrupt massive short-circuit currents safely without catastrophic failure.
Designated by the Ministry of Electric Power Industry, we produce a vast range of high-voltage fuses, including current-limiting variants, capacitor protection fuses, and voltage transformer protection units. Our quality is verified by top-tier institutions including the Electric Power Research Institute and the Xi'an High-voltage Electrical Apparatus Research Institute.
Our technical performance strictly adheres to international standards: ANSI C37,42, DIN 43625, BS 2692, IEC 60282-1, VDE 0636, and GB 15166. We operate under a robust ISO 9001:2000 quality management system, ensuring every fuse link that leaves our factory is a testament to reliability.
The strategic advantage of sourcing from China's leading fuse manufacturer.
Established in 1992, we have over 30 years of specialized manufacturing experience. We have witnessed the evolution of the power industry and have adapted our technologies to meet modern demands.
We don't just sell products; we provide engineering solutions. Whether you need specific current ratings, custom dimensions (e.g., 254x63.5mm), or special environment resistance (oil-immersed), we can customize it.
Quality is non-negotiable. Our products undergo rigorous testing at national high-voltage electrical labs, ensuring they perform exactly as specified during critical fault conditions.
Located in the heart of Yueqing's electrical cluster, we have direct access to high-purity silver for fuse elements, high-grade alumina ceramics, and specialized quartz sand, ensuring consistent quality and competitive pricing.
How our fuses protect critical infrastructure around the globe.
Our H.V. HRC fuses are essential for protecting oil-immersed transformers. In urban grids, they prevent catastrophic failures during lightning strikes or surge loads, maintaining power continuity for millions.
As the "Wholesale EV Fuse Manufacturer," we support the growing network of DC fast chargers. These systems require high-precision fuses that can handle rapid current cycling without premature aging.
From porcelain drop-out fuses in rural substations to high-voltage insulators in heavy industrial zones, our products ensure that short circuits in one sector do not lead to a total blackout.
In recent years, our company has developed rapidly, significantly improving both economic and social benefits. We continuously deepen and refine our quality management system, ensuring we stay ahead of industry curves.
While vigorously developing new products, we prioritize the process flow. High-quality raw materials and sophisticated testing equipment serve as the backbone of our quality assurance. "Shu Rong" brand products have earned a prestigious reputation among domestic and international users for their consistent performance under extreme conditions.
We leverage AI-assisted quality control and precision manufacturing to ensure that every fuse wire and element is positioned with micron-level accuracy, providing predictable and safe clearing times during electrical faults.
