Shu Guang
Established in 1992 as Yueqing Shuguang Fuse Factory, our journey began in Yueqing, Zhejiang—the renowned "Electrical Capital of China." Today, Wenzhou Shuguang Fuse Co., Ltd. has evolved into a leading power technology enterprise. We seamlessly integrate research, development, and high-precision manufacturing to serve the global energy sector.
With over three decades of specialized experience in expulsion fuses and high-voltage circuit protection, we have witnessed the transformation of global power grids. Our commitment to quality is backed by sophisticated testing equipment and a workforce dedicated to "Development by science and technology."
The global demand for OEM Expulsion Fuses is experiencing a significant surge, driven by the modernization of aging infrastructure in North America and Europe, and the rapid electrification of rural regions in Southeast Asia and Africa. In the current industrial climate, expulsion fuses—specifically the "drop-out" variety—remain the most cost-effective and reliable method for protecting overhead distribution transformers and lines from damaging overloads and short circuits.
Modern expulsion fuses are now designed to work in tandem with smart sensors, allowing utilities to pinpoint fault locations faster than ever before.
A transition from traditional porcelain to high-grade polymer insulators is improving durability and reducing the environmental footprint of distribution hardware.
As solar and wind farms proliferate, the need for specialized fuses that can handle bidirectional power flows and high-frequency fluctuations is paramount.
Global procurement officers from utility giants and industrial conglomerates are no longer looking for just a "part." They are seeking partners who provide:
Our products pass rigorous tests at the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center and the Electric Power Research Institute.
We specialize in custom manufacturing. Whether you need specific voltage levels or unique dimensions (e.g., 55*520mm or 88*192mm), our engineering team can deliver.
Located in the Yueqing electrical cluster, we benefit from a world-class supply chain, ensuring high-quality raw materials at competitive price points.
As a designated producer for the Ministry of Electric Power Industry, our technical performance meets and often exceeds global benchmarks. Our product range includes high-voltage fuses, current-limiting fuses, and zinc oxide arresters that conform to:
The "Shu Rong" brand is synonymous with reliability. High-quality raw materials and sophisticated testing equipment are the pillars of our quality assurance system. We ensure that every expulsion fuse link leaving our factory can withstand the harshest environmental conditions—from the humid tropics of Southeast Asia to the freezing winters of Northern Europe.
Reliable overhead line protection for state and private power grids.
Short circuit protection for heavy manufacturing plants and mining operations.
Specialized fuses for reactive power compensation systems.
