Wenzhou Shuguang Fuse Co., Ltd. is strategically located in Yueqing, Zhejiang Province—widely recognized as the "Electrical Capital of China." As a pioneering power technology enterprise, we integrate research, development, production, sales, and comprehensive after-sales service.
Our journey began in 1992 as the "Yueqing Shuguang Fuse Factory." Over three decades, we have evolved from a local workshop into a global powerhouse in the electrical protection industry. Today, we are a leading China Best Potential Transformer Fuses Manufacturer, dedicated to safeguarding power grids through science and quality.
In the modern era of smart grids and renewable energy, Potential Transformer (PT) Fuses play a critical role in maintaining system stability. As transformers are the heart of electrical distribution, their protection is non-negotiable. Globally, the demand for high-reliability fuses is surging, driven by the expansion of urban infrastructure and the retrofitting of aging power grids in North America and Europe.
The global market is shifting towards Current-Limiting High Voltage Fuses that offer faster response times. Manufacturers are now required to meet stringent international standards like IEC 60282-1 to ensure interoperability in global projects.
Miniaturization and environmental resilience are the dominant trends. Future-proof PT fuses must withstand extreme weather conditions while maintaining precise current-limiting characteristics for sensitive electronic measuring equipment.
From the desert solar farms in the Middle East to the high-humidity offshore wind stations in Southeast Asia, our fuses are engineered for localization, ensuring thermal stability and vibration resistance in diverse environments.
Wenzhou Shuguang Fuse Co., Ltd. is designated by the Ministry of Electric Power Industry to produce high-voltage fuses of various voltage levels. Our technical superiority is backed by rigorous testing at national and international high-power test stations, including the Electric Power Research Institute and the Xi'an High-voltage Electrical Apparatus Research Institute.
Our products comply with and exceed the following international standards:
For global procurement managers, sourcing from a China Potential Transformer Fuses Manufacturer like Shuguang offers a unique blend of efficiency and innovation. Our location in the electrical capital allows us to leverage an unparalleled supply chain, reducing lead times and optimizing costs without compromising on the "Shu Rong" brand quality.
Our advantages include:
Our products are exported to various provincial power companies in China and have established a robust presence in Southeast Asia, the Middle East, Africa, and Europe. We adhere to the principle of "Development by science and technology, and survival by quality."
High-voltage current-limiting fuses ensuring safety in distribution networks.
Protecting voltage transformers in heavy industrial environments.
Specialized fuses for wind and solar power transformer stations.
