Shu Guang
Established in 1992 as the Yueqing Shuguang Fuse Factory, we have evolved over three decades into Wenzhou Shuguang Fuse Co., Ltd., a powerhouse in the electrical technology sector. Located in Yueqing, Zhejiang Provinceβthe renowned "Electrical Capital of China"βwe integrate advanced research, development, production, and professional service into a unified core.
As a designated manufacturer for the Ministry of Electric Power Industry, our expertise spans across high-voltage current-limiting fuses, transformer protection fuses, zinc oxide arresters, and drop-out fuses. Our journey is defined by the principle of "Development by science and technology, and survival by quality."
The global shift toward smart grids requires smarter circuit protection. Transformer fuses are no longer passive components; they are critical for maintaining stability in complex, bi-directional power flows common in modern renewable energy networks.
With the rise of solar and wind farms, the demand for specialized oil-immersed back-up protection and HRC fuses has skyrocketed. Our products are optimized for the harsh environments of renewable energy substations.
Heavy industries in the Middle East and Southeast Asia are modernizing. This drives massive procurement needs for reliable, high-voltage current-limiting fuses to protect expensive transformer assets from catastrophic failure.
Our commitment to reliability is backed by rigorous testing. Our products have successfully passed evaluations at the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center and the Xi'an High-voltage Electrical Apparatus Research Institute. We ensure our transformer fuses meet and exceed the following global standards:
Procuring from a specialized China Transformer Fuse Factory like Shuguang offers unique strategic advantages. As the world's manufacturing hub, we benefit from a complete supply chain in Yueqing, allowing for significant cost efficiencies without compromising on technical performance.
Our products are engineered for diverse environments, from urban power distribution to extreme industrial conditions.
