Engineered for high-latitude stability and extreme temperature fluctuations.
Established in 1992 as "Yueqing Shuguang Fuse Factory," Wenzhou Shuguang Fuse Co., Ltd. has evolved into a global titan of power technology. Located in Yueqing, the electrical capital of China, we integrate R&D, production, and service into a seamless high-tech experience.
Analysis of industrial demand, renewable energy growth, and Nordic grid requirements.
Sweden's northern regions, particularly Kiruna and Gällivare, host some of the world's most advanced mining operations. These facilities require ultra-reliable Surge Arresters to protect massive underground ventilation systems and drilling machinery from voltage transients. Our Zinc Oxide (ZnO) arresters are designed to operate in sub-zero Nordic temperatures without performance degradation.
With Sweden's commitment to 100% renewable energy by 2040, the proliferation of wind farms across the Baltic coast and solar arrays in the south has skyrocketed. Surge protection is critical for these distributed energy resources. Our products are optimized for high-altitude wind turbine protection, ensuring grid stability during lightning strikes.
Stockholm and Luleå are global hubs for green data centers. These facilities demand 99.999% uptime. Our high-voltage current-limiting fuses and surge arresters provide a multi-layered defense mechanism, protecting sensitive servers from the subtle yet destructive effects of switching surges.
Meeting the highest international standards for electrical safety.
Our products are designated by the Ministry of Electric Power Industry to produce high-voltage fuses, high-voltage current-limiting fuses, and zinc oxide arresters. Every unit passes the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center and Xi'an High-voltage Electrical Apparatus Research Institute tests.
Compliance Standards: ANSIC37,42, DIN43625, BS2692, IEC282-2-1995, IEC60644, IEC60470, IEC60282-1, IEC269-2 and GB15166.
In recent years, Shuguang Fuse has accelerated its digital manufacturing processes. High-quality raw materials and sophisticated testing equipment are the backing of our quality assurance system. We specialize in customizing products for unique Swedish environmental challenges, including high humidity and corrosive coastal air.
Explore our full range of high-performance components for the Sweden Market.
As the electrification of Sweden accelerates—driven by the decarbonization of the steel industry (HYBRIT project) and the massive expansion of the Northvolt battery gigafactory—the stability of the electrical grid is paramount. A single surge can cause millions in equipment damage and halt production for days.
Our Surge Arrester and High Voltage Fuse products are engineered with high-purity Zinc Oxide varistors, offering superior non-linear characteristics. This ensures that when lightning strikes or switching transients occur in the Swedish countryside, your equipment remains isolated and protected. We understand that Sweden's utility companies like Vattenfall and E.ON demand reliability and long service life. Our company's quality assurance system is complete, having passed ISO9001:2000 certification, ensuring every product shipped to Sweden is a symbol of engineering perfection.
