In the rapidly evolving landscape of Electric Vehicle (EV) infrastructure and smart grid modernization, the demand for reliable circuit protection has reached unprecedented levels. As a premier China-based fuse manufacturer, Wenzhou Shuguang Fuse Co., Ltd. (operating under the renowned "Shu Rong" brand) integrates three decades of expertise with cutting-edge materials science to deliver solutions that exceed international safety benchmarks.
Modern electrical systems face dual challenges: higher energy densities and the need for micro-second response times. Our technical roadmap focuses on Information Gain—utilizing advanced thermal simulations and high-purity silica sand quenching technology to ensure that every fuse we produce offers a definitive safety margin for global OEMs and utility providers.
We are transitioning from traditional mechanical fuses to Smart-Hybrid Protection. This includes high-vibration resistance for automotive environments and ultra-fast clearing capabilities for 800V/1000V EV battery architectures.
Comprehensive protection for Renewable Energy (PV/Wind), EV Charging Stations (EVSE), and Grid Energy Storage Systems (BESS). Our fuses are designed for high DC cyclic loading.
Full adherence to IEC 60282, DIN 43625, and BS 2692. We provide localized technical support to ensure your projects meet regional utility requirements in Europe, MENA, and SE Asia.
Established in 1992 (formerly Yueqing Shuguang Fuse Factory), our company is strategically located in Yueqing, Zhejiang—the Electrical Capital of China. We have grown into a high-tech powerhouse integrating R&D, production, and global service.
Our quality assurance system is ISO 9001:2000 certified. We specialize in:
The "Shu Rong" brand is synonymous with reliability among China's provincial power companies and international partners alike.
By leveraging the Yueqing electrical cluster, we ensure 100% control over raw material quality—from silver element purity to ceramic barrel integrity. This reduces lead times by 30% compared to global competitors.
Our products pass rigorous tests at the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center. Every batch undergoes thermal stability and impulse withstand verification.
Need a specific melting curve? Our engineering team utilizes AI-assisted design to customize fuse links for unique industrial applications, ensuring perfect coordination with your upstream breakers.
Our technical performance meets and exceeds international standards: ANSI C37.42, DIN 43625, BS 2692, IEC 60282-1, VDE 0636.
Optimizing reliability for urban power distribution and rural electrification projects.
