Wenzhou Shuguang Fuse Co., Ltd. is strategically located in Yueqing, Zhejiang Province—widely recognized as the Electrical Capital of China. Our journey began in 1992 as the "Yueqing Shuguang Fuse Factory," and over the last three decades, we have evolved into a high-tech power technology enterprise.
We specialize in the research, development, and high-precision manufacturing of power protection components. As a leading strikerfuse supplier, we integrate cutting-edge science with traditional craftsmanship to ensure that every fuse leaving our facility exceeds global safety standards. Our deep roots in the industry have allowed us to build a reputation for reliability, serving both domestic grid projects and international industrial giants.
With a production heritage spanning over 30 years, we have mastered the complexities of medium and high-voltage protection, ensuring stability in even the most demanding electrical environments.
The global demand for strikerfuses (fuses equipped with mechanical trip devices) is surging due to the modernization of aging power grids. These components are vital for protecting MV switchgear and transformers from thermal damage caused by low-level overloads.
As solar and wind installations expand, the need for specialized current-limiting fuses is paramount. High-voltage fuses with strikers are now being integrated into compact substations that power massive renewable energy farms across Europe and North America.
Modern industrial trends point toward "Smart Fuses." Striker mechanisms are increasingly used to trigger digital monitoring systems, notifying maintenance teams instantly when a fault occurs, thereby reducing downtime and operational costs.
Our status as a premier China high-voltage fuse factory is backed by our designation from the Ministry of Electric Power Industry. We produce a comprehensive range of products including high-voltage current-limiting fuses, power capacitor protection, zinc oxide arresters, and high-voltage insulators.
All our products undergo rigorous validation at top-tier institutions, including:
Our commitment to excellence ensures compliance with international benchmarks: ANSI C37.42, DIN 43625, BS 2692, IEC 60282-1, VDE 0636, and GB 15166. This global compatibility makes us the preferred partner for international procurement teams looking for reliable, high-performance safety components.
Being located in Yueqing allows us access to the world's most concentrated electrical supply chain. This translates to lower raw material costs and faster R&D cycles for our customers.
Global procurement needs vary by region. We can customize striker force, dimensions, and voltage ratings (12kV, 24kV, 36kV) to meet specific local utility requirements in Southeast Asia, the Middle East, or Europe.
Our quality assurance is not just a document; it's a practice. We utilize high-power test stations to ensure that every batch of HRC fuses maintains its current-limiting characteristics under extreme fault conditions.
In Europe, our DIN-standard fuses are widely used in compact ring main units (RMUs). In Africa and Southeast Asia, our drop-out fuses and lightning arresters protect rural distribution lines from harsh weather and frequent surges. In the Industrial Sector, our fuses protect high-value oil-immersed transformers, ensuring that a minor internal fault doesn't lead to a catastrophic explosion.
In recent years, the company has prioritized the process flow and the selection of high-quality raw materials. Our "Shu Rong" brand is synonymous with technological sophistication. We don't just manufacture fuses; we engineer safety systems. While developing new products, we have always attached importance to the consistency of the striker pin's mechanical action, ensuring it triggers the switchgear mechanism with perfect timing.
Our economic and social benefits have improved significantly as we continue to deepen the ISO9001:2000 quality management system. Whether it is a 10kV miniature fuse link or a massive 36kV HRC fuse, the precision of our engineering remains constant.
As the global energy landscape transforms, Wenzhou Shuguang Fuse Co., Ltd. remains committed to the principle: "Development by science and technology, and survival by quality." We sincerely welcome customers from home and abroad to discuss cooperation and work together for the prosperity and development of the electric power industry.
Our complete sales network across China and our expanding footprint in the Middle East, Africa, and Europe make us the ideal partner for your next infrastructure project. Experience the reliability of a factory that has been lead the industry for over 30 years.
