The global demand for high-voltage protection, particularly CE Certification Oil Fuses, has witnessed an unprecedented surge. As nations transition toward smarter and more resilient electrical grids, the role of oil-immersed transformer protection has become a cornerstone of industrial stability. From the rapid industrialization in Southeast Asia to the grid modernization projects across Europe and North America, oil fuses remain the preferred choice for their exceptional thermal management and breaking capacity in liquid-immersed environments.
In today's commercial environment, an "Oil Fuse" is not merely a safety component; it is an investment in infrastructure longevity. Global power utilities and large-scale industrial plants now prioritize components that meet rigorous international standards. As a premier China Oil Fuse Supplier, Wenzhou Shuguang Fuse Co., Ltd. has observed that the market is moving away from generic components toward specialized, high-performance solutions that can withstand extreme environmental variables while maintaining consistent electrical clearing characteristics.

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 Wenzhou Shuguang Fuse Co., Ltd. was "Yueqing Shuguang Fuse Factory" established in 1992.
Over three decades, we have evolved from a local workshop into a globally recognized factory, specializing in high-voltage fuses, current-limiting fuses, and transformer protection devices. Our brand "Shu Rong" has become synonymous with reliability in the power sector.
The modern oil fuse is evolving to support smart grid sensors. We are researching materials that provide more precise time-current characteristics (TCC) to coordinate better with digital circuit breakers and reclosers.
With the rise of renewable energy sources like solar and wind, fault currents in distribution networks have become more complex. Our CE-certified oil fuses are designed to handle higher KA ratings safely.
Sustainability is key. We are optimizing our manufacturing processes to reduce carbon footprints and ensure that our fuse links are compatible with biodegradable dielectric fluids used in modern transformers.
In recent years, the company has developed rapidly, and its economic and social benefits have improved significantly. The company continues to deepen and improve the quality management system. 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 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.
Global procurement officers for state-owned power companies and private electrical contractors seek more than just a product; they seek Authority and Reliability. The requirement for CE Certification is non-negotiable for European markets, ensuring that the oil fuses meet stringent safety, health, and environmental protection requirements. Beyond certification, the industry demands Local Application Expertise.
Primary protection for step-down transformers in municipal and industrial substations, preventing catastrophic failures during overloads.
Protecting the sensitive equipment in solar farm inverters and wind turbine nacelle transformers where space is limited and reliability is critical.
High-voltage protection in harsh mining environments where oil-immersed systems provide the necessary cooling and insulation.
Ensuring fire safety and electrical stability in the internal power distribution of skyscrapers and large commercial complexes.
Wenzhou Shuguang Fuse Co., Ltd. is designated by the Ministry of Electric Power Industry to produce high-voltage fuses of various voltage levels. Our products have passed rigorous testing at the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center and the Xi'an High-voltage Electrical Apparatus Research Institute.
Choosing a specialized factory in China like Shuguang Fuse offers distinct strategic advantages for global businesses. Our expertise is rooted in the "Electrical Capital," where supply chains are highly optimized, allowing us to deliver premium quality at competitive price points.
Our products are exported to various provincial power companies in China, forming a complete national sales network. Internationally, our new high-voltage fuses and current-limiting products are pillars in markets across Southeast Asia, the Middle East, Africa, and Europe.
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 of the electric power industry.
