In the rapidly evolving global electrical infrastructure, the NH Fuse (Niederspannungs-Hochleistungs-Sicherung) remains a cornerstone of safety. As industries transition toward smarter grids and renewable energy sources, the demand for reliable ODM (Original Design Manufacturing) fuse solutions has reached an all-time high. Wenzhou Shuguang Fuse Co., Ltd., located in the heart of China’s electrical capital, Yueqing, stands at the forefront of this industrial revolution.
Today's global commercial environment requires more than just standard components; it demands customized, high-breaking capacity fuses that can withstand the rigors of modern electrical surges. From European industrial complexes to Southeast Asian urbanization projects, the NH fuse is the silent guardian of power distribution units (PDUs), industrial switchgears, and transformer stations.
Industry Expertise Since 1992
Established in 1992 as "Yueqing Shuguang Fuse Factory," our journey began with a singular focus: precision engineering in power safety. Today, Wenzhou Shuguang Fuse Co., Ltd. is a premier power technology enterprise integrating research, development, production, and global sales.
Our facility is designated by the Ministry of Electric Power Industry to produce specialized high-voltage fuses, zinc oxide arresters, and drop-out fuses. We don't just manufacture; we innovate. Our products are the result of decades of empirical data and rigorous testing at national-level laboratories.
Solar and wind farms require specialized NH fuses capable of handling DC currents and fluctuating loads. Our ODM capabilities allow us to adjust fuse characteristics to meet these green energy demands.
The global surge in EV charging stations has created a massive need for HRC current-limiting fuses that ensure fast-acting protection for high-capacity battery systems.
Modern electrical cabinets are becoming more compact. Our NH00 series and custom J-slotted fuses provide maximum protection in a minimal footprint, meeting the localization needs of urban smart cities.
Integration of fuses with monitoring sensors is a rising trend. We are exploring the intersection of traditional melting link technology with IoT-enabled predictive maintenance.
Quality is the bedrock of reliability in high-voltage environments. Our products undergo stringent validation to ensure they meet and exceed international benchmarks.
Based in Yueqing, the "Electrical Capital of China," we have unparalleled access to high-quality raw materials and a sophisticated supply chain, ensuring cost-effective production.
Our products pass through high-power test stations of the Electric Power Research Institute. We utilize sophisticated testing equipment to guarantee performance indicators.
New high-voltage products can be customized and produced at any time according to user needs, making us the preferred supplier for tailored industrial applications.
Our sales network spans across China's provincial power companies and extends to Southeast Asia, the Middle East, Africa, and Europe, ranking us at the industry top.
In recent years, we have deepened our focus on HRC Current-Limiting Fuses. These devices are critical for protecting oil-immersed transformers and capacitor banks. Our "Shu Rong" brand has built a legacy of trust by ensuring that even under extreme fault conditions, the circuit is broken safely and effectively.
Our Industry Applications range from railway electrification and mining power systems to high-rise building distribution and heavy industrial manufacturing. Every fuse we produce is a testament to our commitment: "Development by science and technology, and survival by quality."
