In the modern era of energy transition, High-Quality PtFuses (Power Technology Fuses) have become the backbone of grid stability. As nations shift toward renewable energy sources and expand their EV (Electric Vehicle) infrastructure, the demand for reliable circuit protection has skyrocketed. High-voltage and medium-voltage fuses are no longer just components; they are critical safety assets that prevent catastrophic equipment failure and long-term grid downtime.
Globally, the industrial fuse market is driven by the modernization of aging power grids in North America and Europe, and the rapid urbanization and industrialization in Southeast Asia and Africa. High-power test stations and rigorous international standards like IEC60282 and DIN43625 ensure that these components can withstand the extreme electrical stresses of 21st-century power distribution.

Established in 1992 as "Yueqing Shuguang Fuse Factory," our journey began in the electrical capital of China—Yueqing, Zhejiang Province. Today, Wenzhou Shuguang Fuse Co., Ltd. (SGRong Brand) stands as a premier power technology enterprise. We integrate R&D, production, sales, and service to provide world-class High-Quality PtFuses.
As a designated manufacturer for the Ministry of Electric Power Industry, we specialize in high-voltage fuses for power capacitors, voltage transformer protection, and zinc oxide arresters. Our Commitment to "Survival by Quality" is reflected in our ISO9001:2000 certification and our state-of-the-art testing facilities.
Future-ready PtFuses are designed for smart grid compatibility, offering predictable performance under fluctuating loads from renewable energy inputs.
Our dedicated EV Fuses address the specific high-current, high-speed clearing requirements of electric vehicle battery packs and charging stations.
As equipment gets smaller, our miniature fuse links (10KV 0.63A) provide maximum protection in a compact 8*150mm form factor.
Our products strictly adhere to international benchmarks including ANSIC37.42, DIN43625, BS2692, IEC60282-1, and IEC60644. We ensure all performance tests are qualified through the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center and the Xi'an High-voltage Electrical Apparatus Research Institute.
Used by provincial power companies in China and national grids in Africa for transformer back-up protection and distribution line safety.
Reliable protection for heavy machinery and power capacitors in European and Middle Eastern industrial zones, ensuring 24/7 operational continuity.
Specially engineered oil-immersed transformer fuses for explosive or high-risk environments, meeting stringent safety protocols.
High-voltage current-limiting fuses used in metro systems and railway substations across Southeast Asia to handle high-frequency electrical surges.
"Shu Rong" brand products have earned a high reputation among domestic and foreign users. We adhere to the principle of "Development by science and technology, and survival by quality."
