The global fuse industry is currently undergoing a transformative phase, driven by the massive shift toward electrification and renewable energy integration. As a premier fuse manufacturer and supplier, we recognize that fuses are no longer just "safety links" but critical components in the stability of smart grids, electric vehicle (EV) charging infrastructures, and industrial automation.
Globally, the demand for circuit protection has surged due to the increasing complexity of electronic systems. From 1000V DC solar arrays to 800V EV battery systems, the requirements for breaking capacity, thermal stability, and response speed have reached unprecedented levels. Modern industrial landscapes require manufacturers who can provide not just products, but engineered solutions that comply with diverse international standards like IEC, DIN, and ANSI.
Transitioning to green energy requires high-voltage DC fuses capable of handling the unique fault current profiles of solar PV and wind power systems. We are developing 1500V DC solutions to meet this demand.
Electric vehicles require compact, vibration-resistant fuses with high-speed melting characteristics. Our EV fuse line is optimized for battery pack and charging station protection.
Modern power grids require drop-out fuses and current-limiting fuses that can communicate status or withstand the bidirectional power flows of distributed energy resources.
Automation requires semiconductor protection fuses (uR/aR) with extremely low IĀ²t values to protect sensitive IGBTs and thyristors in motor drives and UPS systems.
Wenzhou Shuguang Fuse Co., Ltd. is located in Yueqing, Zhejiang Province, the "Electrical Capital of China." We are a power technology enterprise integrating research, development, production, sales, and service. The predecessor of our company was "Yueqing Shuguang Fuse Factory," established in 1992.
With over three decades of specialization, we have evolved from a local factory into a globally recognized fuse supplier. Our "Shu Rong" brand is synonymous with reliability in the high-voltage electrical apparatus sector.
Our commitment to "Development by science and technology, and survival by quality" drives every product we manufacture, from miniature fuse links to massive high-voltage current-limiting fuses.
International procurement managers today face the challenge of balancing cost, compliance, and supply chain stability. As a leading fuse manufacturer, we address these needs through:
Our products meet ANSI C37.42, DIN 43625, BS 2692, IEC 60282, and GB 15166 standards. This ensures that whether you are in Europe, Southeast Asia, or the Middle East, our fuses fit your local technical requirements.
We provide solutions for extreme environments:
Being based in Yueqing gives us access to the world's most complete electrical supply chain. We offer:
It is designated by the Ministry of Electric Power Industry to produce high-voltage fuses of various voltage levels, high-voltage current-limiting fuses, high-voltage fuses for power capacitors, voltage transformer protection fuses, zinc oxide arresters, drop-out fuses, high-voltage insulators, etc. product.
All performance tests are qualified through the Electric Power Research Institute and the Xi'an High-voltage Electrical Apparatus Research Institute. Our company's quality assurance system has passed ISO 9001:2000 certification, ensuring every unit leaving our factory is of the highest caliber.
