In the modern era of industrialization and energy transition, the demand for reliable circuit protection components like CE Certified ElectroFuses has reached unprecedented heights. As the world shifts toward decentralized power grids, renewable energy integration (Solar/Wind), and the massive expansion of Electric Vehicle (EV) infrastructure, the "Fuse" has evolved from a simple safety device into a high-tech guardian of billion-dollar assets.
Wenzhou Shuguang Fuse Co., Ltd., located in Yueqing, Zhejiang—the "Electrical Capital of China"—stands at the forefront of this evolution. Established in 1992 (formerly Yueqing Shuguang Fuse Factory), our company has spent over three decades perfecting the art of power technology, integrating R&D, production, and global service.
Modern power systems require fuses that can handle transient overloads while providing precise clearing during actual faults. High-voltage HRC fuses are now designed to work seamlessly with intelligent monitoring systems.
The rise of EV battery systems and fast-charging stations has created a niche for high-speed, high-DC-voltage fuses. Our development in EV-specific protection ensures safety for the next generation of transportation.
Solar inverters and wind turbine transformers require specific protection profiles. Our oil-immersed and current-limiting fuses are engineered for the harsh environments of renewable energy plants.
As switchgear becomes more compact, fuses must provide higher breaking capacities in smaller footprints. Our DIN standard and XRNP series lead the industry in compact protection.
At Wenzhou Shuguang Fuse Co., Ltd., our expertise is validated by the most rigorous international standards. We are designated by the Ministry of Electric Power Industry to produce professional high-voltage fuses, arresters, and insulators.
Compliance Standards: Our products meet and exceed:
Our company's quality assurance system is complete, having passed ISO9001:2000. Products have been tested by the Xi'an High-voltage Electrical Apparatus Research Institute and the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center. All performance tests are qualified, ensuring the highest level of reliability for our global partners.
From the bustling industrial zones in Europe to the expanding rural grids in Africa, our fuses serve diverse needs:
Our products are exported to Southeast Asia, the Middle East, Africa, and Europe, ranking among the top in the industry for domestic and international sales volume.
Located in Yueqing, we leverage a world-class supply chain. Our facility uses sophisticated testing equipment to ensure every fuse link meets technical conditions before shipment.
We don't just sell off-the-shelf. New products can be customized and produced at any time according to specific user needs, voltage levels, or dimensions.
Our brand has enjoyed a high reputation among domestic and foreign users for decades. We adhere to the principle: "Development by science and technology, survival by quality."
