The global electrical landscape is undergoing a paradigm shift towards high-efficiency power distribution and renewable energy integration. ODMCapacitorFuses have become critical components in this evolution. As power grids worldwide modernize, the demand for sophisticated capacitor bank protection has surged. In the industrial sector, capacitor fuses are no longer just safety devices; they are essential for maintaining Power Factor Correction (PFC) stability, which reduces energy waste and operational costs.
Current trends indicate a move toward Smart Grid compatibility. Manufacturers are now integrating sensors and advanced materials to ensure fuses can withstand the harmonic distortions often found in modern solar and wind power plants. This transition has placed a spotlight on the China ODM manufacturer market, where the ability to rapidly innovate and produce high-performance protection devices meets the urgent needs of global utility providers and heavy industries.
Years of Expertise
Certified Quality
Exporting Countries
Located in Yueqing, Zhejiang—the Electrical Capital of China—Wenzhou Shuguang Fuse Co., Ltd. is a power technology pioneer. Our journey began in 1992 as the "Yueqing Shuguang Fuse Factory." Over the past three decades, we have evolved into a comprehensive power technology enterprise integrating R&D, production, sales, and localized service.
We are honored to be designated by the Ministry of Electric Power Industry to produce high-voltage fuses across various voltage levels. Our product portfolio includes high-voltage current-limiting fuses, capacitor protection fuses, transformer protection fuses, zinc oxide arresters, and high-voltage insulators. Our "Shu Rong" brand is synonymous with reliability in both the domestic Chinese market and international sectors.
Global procurement teams from Europe, the Middle East, and Southeast Asia are increasingly looking for ODM (Original Design Manufacturer) partners rather than off-the-shelf suppliers. This is because every power grid has unique technical requirements—varying voltage levels, environmental stressors, and specific compliance standards like IEC or ANSI.
Our designs meet ANSIC37.42, DIN43625, and BS2692 standards, ensuring total compatibility with global infrastructure.
We develop new products customized to user needs, from specialized dimensions to unique melting characteristics.
As a China-based factory, we leverage local supply chains to provide high-voltage protection at competitive price points.
Our company adheres to the core principle: "Development by science and technology, and survival by quality." We utilize high-quality raw materials and sophisticated testing equipment, ensuring all performance indicators align with international technical conditions. This makes us a reliable partner for state-owned power companies and private electrical engineering firms alike.
In the world of high-voltage electrical apparatus, reliability is non-negotiable. Our authority is backed by a complete quality assurance system and rigorous testing. All products have passed inspections at the most prestigious laboratories in China, including the Xi'an High-voltage Electrical Apparatus Research Institute and the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center.
We comply with a vast array of international and domestic standards:
Our products serve a wide spectrum of localized industrial applications. In urban power grids, our drop-out fuses and lightning arresters protect thousands of transformers from overcurrent and atmospheric surges. In heavy industrial plants—such as steel mills or chemical refineries—our high-voltage current-limiting fuses are essential for protecting large-scale power capacitors and motors.
We have built a complete sales network throughout China, supplying various provincial power companies. Beyond our borders, our export volume ranks among the top in the industry for regions including:
Economic and social benefits have improved significantly in recent years as we continue to deepen our quality management system. While vigorously developing new products, we always attach importance to the process flow. High-quality raw materials and sophisticated testing equipment are the backing of our quality assurance system. Our commitment to "Survival by Quality" means that every fuse leaving our factory is a testament to Chinese engineering excellence.
