In the modern era of high-voltage transmission and smart grids, CE Certification Switchgear Fuses serve as the critical line of defense for electrical infrastructure. Globally, the demand for high-performance protection devices is surging as industrial automation and urbanization place immense stress on existing power grids.
The industry is moving toward "Smart Protection" systems. Integration with IoT sensors for real-time monitoring and the rise of Renewable Energy Interconnects are driving manufacturers to produce fuses that can handle variable loads and harsh environmental conditions without compromising safety.
As Electric Vehicle (EV) adoption accelerates, the need for specialized high-voltage fuses for charging stations and battery protection has redefined the manufacturer's scope. China has emerged as the global hub for this technological pivot, providing the scale and R&D necessary for global markets.
Wenzhou Shuguang Fuse Co., Ltd. is strategically located in Yueqing, Zhejiang Provinceโwidely recognized as the Electrical Capital of China. We are a power technology enterprise that seamlessly integrates research, development, production, sales, and service.
The legacy of our company began in 1992 as the "Yueqing Shuguang Fuse Factory." Over three decades, we have transformed from a local specialist into a global leader in circuit protection technology.
We are proudly designated by the Ministry of Electric Power Industry to produce high-voltage fuses across various voltage levels. Our products undergo rigorous testing at the highest authority labs, including the Xi'an High-voltage Electrical Apparatus Research Institute.
Our technical performance adheres to elite international standards:





From the arid deserts of the Middle East to the industrial corridors of Europe, our fuses are deployed in Oil-Immersed Transformers, Substation Switchgears, and Urban Power Distribution Units. Each environment demands specific tolerances that our engineers customize for maximum reliability.
Global enterprises seek suppliers who offer Cost-Efficiency without Safety Compromise. Our factory provides bulk manufacturing capabilities, OEM/ODM support, and a complete supply chain that ensures timely delivery even for massive infrastructure projects.
We work closely with provincial power companies in China and international contractors to supply high-voltage current-limiting fuses that protect billions of dollars in electrical assets daily.
The "Shu Rong" brand is synonymous with quality. Our rapid development is fueled by continuous investment in sophisticated testing equipment and high-quality raw materials. We believe in "Survival by Quality," which is why our high-voltage current-limiting fuses exceed the performance indicators of standard market offerings.
While developing new products, we have always attached importance to the process flow. High-quality raw materials and sophisticated testing equipment are the backing of the quality assurance system. All performance indicators are in line with the corresponding technical conditions, and new products can be customized and produced at any time according to user needs.
