Wenzhou Shuguang Fuse Co., Ltd. is a leading power technology enterprise based in Yueqing, Zhejiang—the renowned "Electrical Capital of China." With roots tracing back to the Yueqing Shuguang Fuse Factory founded in 1992, we have over three decades of specialized experience in circuit protection. We integrate R&D, advanced production, and global service to provide high-voltage solutions that power nations.
Designated by the Ministry of Electric Power Industry, our factory produces high-voltage current-limiting fuses and zinc oxide arresters that meet rigorous international benchmarks. Our systems are certified by ISO9001:2000, and our products strictly comply with IEC60282, DIN43625, BS2692, and ANSI C37.42 standards. Every unit undergoes testing at the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center.
Our footprint extends far beyond China's provincial power grids. As a premier China WholesaleFuseNh Manufacturer, we export heavily to Southeast Asia, the Middle East, Africa, and Europe. Our commitment to "Development by science and survival by quality" ensures that "Shu Rong" brand products remain the top choice for international infrastructure projects.
The global demand for NH Fuses (HRC Fuses) and high-voltage protection devices is reaching an all-time high. As industrial automation expands and power grids transition toward renewable energy, the reliability of low and high-voltage fuses becomes the backbone of safety. In the 2024 landscape, "WholesaleFuseNh" refers not just to a component, but to the critical safety interface in transformer stations, industrial motor controls, and municipal power distribution units.
The industry is moving toward Smart Grid Integration. Traditional fuses are being enhanced with sensory capabilities to monitor heat and load in real-time. Furthermore, the push for Green Energy (Solar PV and Wind) requires specialized DC fuses and high-breaking capacity NH fuses that can handle the unique fluctuating loads of renewable sources. Our R&D team is actively developing next-generation "Shu Rong" fuses that cater to the Electric Vehicle (EV) charging infrastructure and energy storage systems (BESS).
International buyers are increasingly looking for Compliance and Customization. In Europe, DIN-standard HRC fuses are the gold standard, while North American markets demand ANSI compliance. As a versatile China supplier, we bridge this gap by offering multi-standard certification. Global EPC (Engineering, Procurement, and Construction) companies require partners who can offer large-volume wholesale capabilities without compromising on the precision of the fuse element's time-current characteristics.

Being located in Yueqing allows us to leverage the world's most concentrated Electrical Supply Chain. This proximity enables us to source high-grade silver fuse elements, high-purity quartz sand (for arc quenching), and industrial-strength ceramic bodies at competitive costs. We pass these savings directly to our wholesale partners, ensuring the best price-to-performance ratio in the industry.
Our WholesaleFuseNh products are designed for diverse environments. In Middle Eastern deserts, our fuses are built to withstand high ambient temperatures; in Coastal Europe, our insulators and fuse holders feature enhanced corrosion resistance. Whether it's for an oil-immersed transformer in a remote grid or a miniature fuse link for precision equipment in a smart factory, we provide the specific protection needed for that locale.
Unlike standard distributors, Wenzhou Shuguang Fuse Co., Ltd. offers OEM and ODM services. We can calibrate the melting point and breaking capacity of our HRC fuses to meet specific industrial requirements. Our internal lab utilizes sophisticated testing equipment to simulate high-current short circuits, ensuring that when a fault occurs in your system, our fuse responds within milliseconds to protect your multi-million dollar investments.
As a leading power technology enterprise, Wenzhou Shuguang Fuse Co., Ltd. continues to deepen and improve its 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. "Shu Rong" brand products have enjoyed a high reputation among domestic and foreign users.
Our technical performance meets ANSIC37,42, DIN43625, BS2692, IEC282-2-1995, IEC60644, IEC60470, IEC60282-1, IEC269-2 and GB15166.1, GB15166.2, GB15166.5. We are a trusted partner for national power grids across Asia and Europe.
Wenzhou Shuguang Fuse Co., Ltd. combines 30+ years of expertise with cutting-edge manufacturing to deliver the world's most reliable high-voltage fuses.
