Established in 1992 as "Yueqing Shuguang Fuse Factory," Wenzhou Shuguang Fuse Co., Ltd. has evolved into a global titan in power technology. Located in the world-renowned "Electrical Capital of China"—Yueqing, Zhejiang Province—we are a specialized power technology enterprise. Our core competency lies in the seamless integration of research, development, production, and worldwide service.
With over three decades of experience, we have transitioned from a local manufacturer to a designated producer for the Ministry of Electric Power Industry. Our journey is defined by a relentless pursuit of engineering excellence, ensuring that every high-voltage fuse, arrester, and insulator we produce meets the most stringent safety benchmarks.
As the global energy landscape shifts toward smart grids and renewable integration, the demand for reliable circuit protection has skyrocketed. High-voltage fuses are the primary line of defense for critical infrastructure, from urban substations to remote wind farms.
The rise of solar PV and wind energy requires specialized DC and high-speed fuses. OEMGoodFuses stays ahead by developing products tailored for high-frequency switching environments and the unique thermal stresses of renewable energy converters.
Electric vehicle (EV) charging infrastructure demands extreme reliability and compact form factors. Our wholesale EV fuse range is specifically engineered to handle the high current surges and rapid protection speeds necessary for modern automotive safety.
Industrial 4.0 requires fuses that are not only robust but also consistent. Our manufacturing processes utilize precision materials to ensure that clear-out times and interruption ratings are perfectly predictable, reducing downtime in automated factories.
Choosing a partner in the "Electrical Capital of China" means tapping into a massive, integrated supply chain. Wenzhou Shuguang Fuse Co., Ltd. offers a unique blend of cost-efficiency and high-end engineering. Our factory leverages localized raw material sourcing (high-purity ceramics, silver fuse elements, and quartz sand) to keep costs competitive without compromising on the technical performance that global EPC contractors demand.
Furthermore, our ability to customize products is a key differentiator. Whether you require a specific mounting dimension for a legacy substation in Europe or a specialized current rating for a transformer in the Middle East, our R&D team can prototype and produce custom solutions rapidly. We don't just sell components; we provide engineered safety systems that are validated in high-power test stations.
Authoritativeness is built through rigorous testing. Our products have successfully passed inspections at the Electric Power Research Institute, the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center, and the Xi'an High-voltage Electrical Apparatus Research Institute. We maintain full compliance with:
IEC 60282-1, IEC 282-2, IEC 60644, IEC 60470
DIN 43625 (German), BS 2692 (British), ANSI C37.42 (American)
GB 15166.1, GB 15166.2, GB 15166.5, DL/T 640-1997
ISO 9001:2000 Quality Management System Certification
Our fuses are widely used for the protection of capacitor banks in power factor correction units, preventing catastrophic failures and ensuring grid stability across European and Asian networks.
Voltage transformer protection requires high-precision current limiting. Our XRNP series is a staple for utility companies in the Middle East and Africa where harsh environmental conditions demand robust enclosures.
Drop-out fuses and high-voltage insulators from Wenzhou Shuguang are utilized in thousands of provincial power companies across China and Southeast Asia, providing reliable arc quenching and isolation.
Whether you are an EPC contractor looking for bulk supply or a utility company seeking technical replacements, Wenzhou Shuguang Fuse Co., Ltd. provides the reliability and scientific development needed to power the future. We believe in "Survival by Quality," ensuring that every product leaving our Yueqing facility is a testament to Chinese manufacturing excellence.
