Shu Guang
Established in 1992 as "Yueqing Shuguang Fuse Factory," Wenzhou Shuguang Fuse Co., Ltd. has evolved into a premier power technology enterprise. Located in Yueqing, the electrical capital of China, we integrate advanced R&D, sophisticated production, and global sales service.
For over three decades, we have focused on the core mission of circuit protection. Our journey from a local manufacturer to a globally recognized CE-certified factory reflects our commitment to excellence. We don't just make fuses; we engineer peace of mind for electrical infrastructure worldwide.
In the current global era, general-purpose fuses are the unsung heroes of power grids. With the rise of smart cities and industrial automation, the demand for high-reliability circuit protection is skyrocketing. Our CE certified fuses provide the essential safety barrier for transformers, capacitors, and motors.
As the world transitions to green energy, solar farms and wind turbines require specialized fuse links. The technical complexity of protecting DC circuits in PV systems has driven the industry toward higher standards, which Shuguang Fuse meets with precision-engineered current-limiting technology.
From the high-rises of Dubai to the industrial zones of Europe, reliable power distribution is a prerequisite. Localized application scenarios—such as high-voltage switchgear in underground substations—demand the compact and efficient performance found in our HRC fuse links.
Staying ahead of the curve through technology and compliance.
Modern electrical panels have limited space. We are developing miniature high-voltage fuse links that maintain massive breaking capacities (up to 50kA or more) in smaller footprints, adhering to the DIN 43625 standard.
The rapid growth of Electric Vehicles (EVs) has created a new segment: EV fuses. These require extreme resistance to vibration and temperature cycling. Our factory is at the forefront of producing wholesale EV fuses for global charging station manufacturers.
The next generation of fuses involves "smart" indicators. While traditional fuses use mechanical strikers, the industry is moving toward integrated sensors that signal a fault directly to the control center, a trend we are actively researching.
Our technical performance meets and exceeds the world's most rigorous standards.
Our products have successfully passed testing at the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center and the Xi'an High-voltage Electrical Apparatus Research Institute. Our quality assurance system is ISO 9001:2000 certified.
Compliance with IEC 60282-1, IEC 60644, IEC 60470, and DIN 43625 ensures our products are ready for the European Union and international markets. Our CE certification is a testament to our safety engineering.
We provide solutions conforming to ANSI C37.42 and BS 2692, allowing us to serve diverse global regions with different grid configurations.
As a designated producer for the Ministry of Electric Power Industry, we strictly follow GB 15166.1, GB 15166.2, and DL/T 640-1997.
Located in the heart of Yueqing, we have immediate access to the world's most efficient electrical supply chain. This allows us to source the highest quality raw materials (high-purity silver, specialized ceramics) at competitive prices, passing the savings to our global clients.
Unlike distributors, as a factory, we can customize products based on specific user needs. Whether it's a unique voltage rating or a specific mounting requirement, our engineering team can prototype and produce it quickly.
Quality is our survival. We utilize sophisticated testing equipment—including high-power test stations—to ensure every fuse that leaves our factory performs exactly as specified during a fault event.
In recent years, our economic and social benefits have improved significantly. We continue to deepen and improve our quality management system. While vigorously developing new products, we have always attached importance to the process flow. Our "Shu Rong" brand products have enjoyed a high reputation among domestic and foreign users for their stability and precision.
The company adheres to the principle of "Development by science and technology, and survival by quality." We invite partners from the Middle East, Southeast Asia, Africa, and Europe to collaborate for a brilliant future in the electric power industry.
Our products are exported to various provincial power companies in China and across the globe. We have established a complete sales network and good business contacts in numerous international regions.
Ensuring the safety of municipal grids and rural electrification projects through high-voltage expulsion fuse links and drop-out fuses.
Protecting heavy machinery, motors, and industrial furnaces from catastrophic over-current damage.
Providing essential circuit protection for railway systems and large-scale commercial complexes.
