Wenzhou Shuguang Fuse Co., Ltd. is a premier power technology enterprise headquartered in Yueqing, Zhejiang Province—widely recognized as the "Electrical Capital of China." Since its inception as the "Yueqing Shuguang Fuse Factory" in 1992, the company has evolved into a global powerhouse integrating R&D, advanced production, sales, and comprehensive after-sales service.
Over three decades, we have dedicated ourselves to mastering the complexities of high-voltage circuit protection. Our mission is to safeguard modern electrical grids by providing reliable, high-performance expulsion type fuses and current-limiting solutions that exceed international safety benchmarks.
With the global push toward "Smart Grids," the demand for expulsion fuses has surged. These devices are critical for protecting distribution transformers in aging infrastructures and new renewable energy integrations.
Solar and wind farms require specialized overcurrent protection. Our ODM services focus on developing fuses that handle the unique load profiles of renewable energy generators.
Developing nations are prioritizing electrification. Our factory provides high-durability, cost-effective expulsion fuses that are essential for large-scale rural electrification projects.
The global expulsion type fuse market is undergoing a significant transformation. As industries move toward higher voltage levels (up to 36kV and beyond) to minimize transmission losses, the technical requirements for expulsion-type cutouts have become more stringent. Modern procurement demands emphasize not just the "interrupting capacity" but also the weather-resistance of the materials used in the fuse tubes and insulators.
In North America, the ANSI standard dominates, whereas Europe and much of Asia follow the IEC framework. As a leading China ODM Expulsion Type Fuse Factory, Wenzhou Shuguang Fuse Co., Ltd. bridges this gap by offering cross-standard compatibility, ensuring that our products serve the specific technical nuances of every continent.
Technological innovation is the heartbeat of Shuguang. In recent years, we have invested heavily in automated assembly lines and digital testing stations to ensure 100% reliability. While vigorously developing new products, we maintain a ruthless focus on process flow.
Our "Shu Rong" brand is synonymous with quality. By utilizing high-purity raw materials and sophisticated testing equipment, we ensure that every fuse link and expulsion tube meets exact specifications. Whether it is a custom time-current characteristic or a specific mechanical strength for extreme environments, our engineering team can provide tailor-made ODM solutions.
Our highest technical performance meets ANSIC37, DIN43625, BS2692, IEC60282, VDE0636, and national GB standards. We are designated by the Ministry of Electric Power Industry to produce professional high-voltage fuses, and our ISO9001:2000 quality system ensures consistent excellence.
Protection of compact substations and underground distribution networks where space is limited and reliability is paramount.
Our expulsion fuses are engineered with high-grade polymeric insulators or ceramic bodies to withstand high humidity, coastal salt-spray, and extreme temperature fluctuations.
Designed for power capacitors and voltage transformer protection in steel mills, mining operations, and petrochemical plants.
As a China ODM Expulsion Type Fuse Factory, we understand that "one size fits all" does not apply to global electrical engineering. For instance, procurement requirements in the Middle East often emphasize high-temperature resistance and dust-sealing for fuse holders. In contrast, European clients often prioritize environmental sustainability and recyclability of the materials used. We offer localization services that modify product dimensions, mechanical fittings, and electrical properties to suit these regional preferences seamlessly.
Our presence spans across Southeast Asia, the Middle East, Africa, and Europe. Our domestic sales rank at the top of the industry, fueled by our partnership with various provincial power companies in China. Here is why global enterprises choose us as their preferred factory:
Our products are exported to various provincial power companies and have established a complete sales network. We sincerely welcome domestic and foreign customers to discuss cooperation and create a brilliant future together.
