Wenzhou Shuguang Fuse Co., Ltd. is strategically located in Yueqing, Zhejiang Province—the renowned "Electrical Capital of China." As a premier power technology enterprise, we integrate professional research, development, production, and global sales. Our journey began in 1992 as the "Yueqing Shuguang Fuse Factory," and for over three decades, we have remained at the forefront of the electrical protection industry.
Under our signature brand "Shu Rong", we have built a reputation for excellence. We are designated by the Ministry of Electric Power Industry to manufacture high-voltage fuses across various voltage levels, including specialized current-limiting fuses and transformer protection devices. Our longevity in the market is a testament to our commitment to E-E-A-T principles: Experience in engineering, Expertise in high-voltage physics, Authoritativeness in standard compliance, and Trustworthiness in every fuse we ship.
The global demand for DIN standard fuses is surging as industries transition toward smart grids and renewable energy.
The rise of urbanization and industrialization in emerging economies (Southeast Asia, Africa) and the grid modernization in Europe and North America have created a massive demand for standardized DIN fuses. These components are critical for safeguarding expensive switchgear and transformer units.
As the world pivots to Electric Vehicles, the need for specialized EV Fuses and high-speed protection has skyrocketed. Our factory is at the cutting edge, developing fuses that handle the unique DC load profiles of modern charging infrastructure.
Modern electrical grids require components that offer precision and reliability. DIN standard current-limiting fuses are essential for preventing catastrophic failures in distributed energy systems, where renewable inputs like solar and wind can cause sudden fluctuations.
Being based in Yueqing gives us immediate access to the world’s most efficient electrical component supply chain, allowing us to source premium raw materials and maintain competitive pricing without compromising on quality.
We don’t just manufacture; we innovate. Our ODMDinFuses service allows global clients to customize technical specifications—voltage ratings, breaking capacities, and physical dimensions—to meet specific localized application needs.
Our facility is equipped with high-power testing equipment. Every product undergoes rigorous performance tests validated by the Xi'an High-voltage Electrical Apparatus Research Institute and other national quality supervision centers.
Quality is our survival mechanism. Our company’s quality assurance system is ISO9001:2000 certified, and our technical performance meets or exceeds the following international benchmarks:
Our products have passed tests at the high-power test station of the Electric Power Research Institute of the Ministry of Electric Power, ensuring absolute reliability in the field.
In recent years, Wenzhou Shuguang Fuse Co., Ltd. has developed rapidly, utilizing high-quality raw materials and sophisticated testing equipment to back our quality assurance. We focus on the entire process flow—from the selection of pure silver elements to the precision of the quartz sand filling.
Primary Application Scenarios:
Our products are exported to various provincial power companies in China, forming a complete domestic sales network. Beyond China, we have established robust business contacts in Southeast Asia, the Middle East, Africa, and Europe. We rank among the top in the industry for domestic sales and international export volume. We adhere to the core principle: "Development by science and technology, and survival by quality."
