Wenzhou Shuguang Fuse Co., Ltd. is strategically located in Yueqing, Zhejiang Province—widely recognized as the "Electrical Capital of China." We are a powerhouse technology enterprise that seamlessly integrates R&D, advanced production, global sales, and comprehensive after-service.
Our journey began in 1992 as the "Yueqing Shuguang Fuse Factory." For over three decades, we have evolved from a local workshop into a leading global manufacturer of CECertificationFuseNh systems. Our deep-rooted expertise allows us to provide critical protection for power grids, ensuring safety and reliability in the most demanding industrial environments.
The global power protection market is undergoing a seismic shift. As nations transition toward smart grids and renewable energy sources, the demand for high-reliability components like CECertificationFuseNh (NH Fuses) has skyrocketed. These components are the unsung heroes of electrical infrastructure, preventing catastrophic equipment failure during overloads or short circuits.
Modern industrial trends favor fuses that can withstand high-frequency switching and provide precise current-limiting capabilities to protect sensitive electronic grid controllers.
With the rise of solar farms and EV charging networks, specialized HRC fuses are essential to handle DC and high-voltage AC protection requirements.
CE Certification is no longer just a "plus"—it is a mandatory requirement for entering European and many Middle Eastern markets, ensuring user safety and equipment longevity.
Our products are designated by the Ministry of Electric Power Industry for high-voltage applications across multiple voltage levels.
We take pride in our rigorous testing protocols. All our high-voltage current-limiting fuses and power capacitor protection devices have passed stringent evaluations at the Electric Power Research Institute, the National High-voltage Electrical Apparatus Quality Supervision Center, and the Xi'an High-voltage Electrical Apparatus Research Institute.
International buyers, from engineering firms in Germany to utility contractors in Brazil, seek more than just a product; they seek a stable supply chain partner. Our factory addresses these needs by offering:
Protecting step-down transformers and municipal distribution boxes across urban grids.
Safeguarding mining equipment and motor starters from massive current surges.
Specialized expulsion fuses for harsh, explosive environments where reliability is non-negotiable.
Protecting photovoltaic (PV) string inverters and energy storage systems (BESS).
In recent years, Wenzhou Shuguang has accelerated its digital transformation. By integrating high-quality raw materials with sophisticated automated testing equipment, we ensure that every Shu Rong brand fuse exceeds long-term development expectations.
We have pioneered the use of composite polymer insulators alongside traditional porcelain. This duality allows us to serve markets with different environmental stressors—polymer for high-pollution coastal areas and porcelain for high-heat desert environments.
Our major markets span across various provincial power companies in China, Southeast Asia, the Middle East, Africa, and Europe. We are consistently ranked among the top in the industry for domestic and international sales volume.
Being based in Yueqing means we have immediate access to the world's most robust electrical component ecosystem, reducing lead times significantly.
Our ISO9001:2000 certified system is not just a certificate; it’s a culture of precision that governs every fuse link leaving our floor.
We specialize in manufacturing products that meet regional standards like DIN (Germany), BS (UK), and ANSI (USA), making local installation seamless.
