Established in 1992, originally as "Yueqing Shuguang Fuse Factory," our journey began in the heart of China's electrical industry—Yueqing, Zhejiang. Today, Wenzhou Shuguang Fuse Co., Ltd. stands as a premier power technology enterprise that seamlessly integrates R&D, production, sales, and comprehensive after-sales service. As a leading China BestGoodFuses supplier, we have spent over three decades perfecting the art of electrical circuit protection.
With a strategic location in the "Electrical Capital of China," we leverage a mature supply chain and cutting-edge manufacturing processes to serve global markets including Southeast Asia, the Middle East, Africa, and Europe.
The global shift toward Smart Grids and Renewable Energy (Wind/Solar) is driving unprecedented demand for high-reliability circuit protection. We are evolving our HRC fuses and current-limiting technologies to match the sensitivity of modern digital power systems.
The Electric Vehicle revolution requires specialized EV Fuses capable of handling high DC voltages. As a forward-thinking supplier, we have developed specific lines for EV battery protection and charging infrastructure, ensuring safety in the transport of tomorrow.
Global procurement needs are shifting toward "One-Stop Shop" manufacturers. International buyers now prioritize suppliers who can offer DIN, IEC, and ANSI standards simultaneously, a capability that defines our competitive edge in the global market.
Our products are not just manufactured; they are engineered to meet the world's most stringent technical conditions. We are designated by the Ministry of Electric Power Industry to produce high-voltage fuses across various voltage levels. Every component—from zinc oxide arresters to drop-out fuses—undergoes rigorous testing at:
Standards Compliance: ANSI C37.42, DIN 43625, BS 2692, IEC 60282-1, IEC 282-2-1995, IEC 60644, VDE 0636, and GB 15166.
Our HRC back-up fuses are specifically designed for oil-immersed transformers, providing critical short-circuit protection in rural and urban substations across Africa and Southeast Asia.
Specialized capacitor protection fuses ensure that industrial plants in Europe can maintain power factor correction without the risk of cascading failures due to capacitor ruptures.
In high-altitude wind farms or coastal solar arrays, our polymer insulators and drop-out fuses provide weather-resistant, durable performance under extreme environmental stress.
As a prominent China BestGoodFuses manufacturer, we offer more than just products; we offer a strategic partnership. Our factory in Yueqing is at the epicenter of electrical innovation, allowing us to:
We utilize high-quality raw materials and sophisticated testing equipment. Our "Shu Rong" brand is synonymous with reliability among domestic and international users.
Whether you need specific dimensions (like our 55*520mm HV fuse) or custom voltage ratings for unique local grids, our R&D team can produce prototypes and mass-produce at scale.
Our integrated production cycle—from research to service—ensures that we meet the tight deadlines required by global power utility companies and construction firms.
In recent years, the company has developed rapidly, and its economic and social benefits have improved significantly. While vigorously developing new products, it has 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. "Shu Rong" brand products have enjoyed a high reputation among domestic and foreign users.
The company adheres to the principle of "Development by science and technology, and survival by quality". We sincerely welcome customers from home and abroad to discuss cooperation and work together for the prosperity and development of the electric power industry. Whether you are looking for high-voltage fuses, lightning arresters, or customized EV power protection, Wenzhou Shuguang Fuse Co., Ltd. is your trusted China partner.
