Wenzhou Shuguang Fuse Co., Ltd.
Located in Yueqing, Zhejiang Province—the renowned Electrical Capital of China—Wenzhou Shuguang Fuse Co., Ltd. stands as a beacon of power technology excellence. Our journey began in 1992 as "Yueqing Shuguang Fuse Factory," and over the decades, we have evolved into a comprehensive enterprise integrating research, development, production, and global sales service.
We specialize in the engineering of medium and high-voltage protection systems, ensuring that power grids across the globe operate with maximum safety and efficiency. Our commitment to quality is rooted in our heritage, combining traditional manufacturing craftsmanship with modern AI-driven production technologies.
The global switchgear fuse market is experiencing a paradigm shift driven by the modernization of aging electrical grids in developed nations and rapid urbanization in emerging economies. As energy consumption rises, the demand for reliable China SwitchgearFuses Manufacturers has skyrocketed, particularly for units that can handle higher breaking capacities and offer faster response times.
The transition toward Smart Grids requires protection components that are not only robust but also compatible with automated monitoring systems. We are at the forefront of this trend, developing current-limiting fuses that minimize electromagnetic stress during faults, thereby protecting sensitive digital equipment within the switchgear assembly.
With the global push for carbon neutrality, solar and wind farms are being integrated into the main grid at an unprecedented rate. This creates a specific need for high-voltage fuses capable of handling the unique load profiles and DC-fault characteristics of renewable installations—a niche where our factory excels.
As a premier China SwitchgearFuses Factory, we provide more than just products; we deliver competitive advantages that help our partners win in their local markets.
Our quality assurance system is ISO9001:2000 certified, ensuring every fuse link leaving our factory meets the highest technical performance benchmarks. We are designated by the Ministry of Electric Power Industry to produce specialized protection equipment.

Our H.V. HRC fuses are essential for protecting oil-immersed and dry-type transformers. In urban substations in Europe and the Middle East, these fuses provide critical back-up protection, preventing catastrophic failures during internal transformer faults.
The rise of Electric Vehicles has created a surge in demand for DC high-voltage fuses in charging stations. Our specialized EV fuses are engineered to handle the high-speed interruption required for DC circuit safety.
In industrial power factor correction units, our capacitor protection fuses ensure that any single unit failure is isolated immediately without compromising the entire bank, maintaining the stability of the industrial power supply.
For applications in Southeast Asia and Africa, our porcelain and polymeric insulators combined with drop-out fuses provide reliable service even in areas with high humidity, salt spray, or extreme dust.
Our "Shu Rong" brand enjoys a high reputation both domestically and internationally. We have established a robust sales network that spans across:
We believe in "Development by science and technology, and survival by quality." This philosophy has allowed us to rank among the top in the industry for domestic sales and export volume.
While we produce a vast range of standard high-voltage current-limiting fuses, we also offer customization. Whether it is a specific dimension (like our 88*192mm HRC links) or a unique voltage rating, our engineering team can provide tailor-made solutions for global Switchgear OEMs.
