Established in 1992 as "Yueqing Shuguang Fuse Factory," our organization has evolved into a premier power technology enterprise. Located in Yueqing, Zhejiang—famously known as the Electrical Capital of China—we integrate high-end research, development, and large-scale production of electrical protection components.
With over three decades of expertise, we specialize in high-voltage fuses across various voltage levels, including current-limiting variants, power capacitor protectors, and transformer specialized fuses. Our commitment to quality and technical precision has made us a designated producer for major power industry sectors.
The global demand for reliable power distribution is at an all-time high, driven by the rapid expansion of smart grids and renewable energy integration.
Modern transformer fuses are moving toward "smart" capabilities, allowing for better fault detection and integration with SCADA systems for real-time monitoring.
Solar and wind farms require specialized protection for their step-up transformers. Manufacturers are now designing fuses that handle the unique cycling loads of green energy.
As urban space becomes premium, compact substations require high-performance fuses with smaller footprints without compromising on breaking capacity.
Compliance with RoHS and REACH standards is becoming mandatory, pushing manufacturers to innovate with recyclable porcelain and polymer materials.
With increasing grid density, the potential fault currents are higher. Modern HRC fuses must now support breaking capacities up to 50kA or higher.
The industrial market now demands customized solutions rather than off-the-shelf products to meet specific regional environmental challenges.
Our products aren't just manufactured; they are engineered to meet and exceed global safety benchmarks.
Our high-voltage and current-limiting fuses have undergone rigorous testing at world-class facilities, including the Electric Power Research Institute and the Xi'an High-voltage Electrical Apparatus Research Institute. Every product leaving our factory is backed by a legacy of safety and performance.
We strictly adhere to international standards including:
In Southeast Asia, high humidity and heat require our salt-spray resistant polymer insulators. In Europe, the focus is on high-precision DIN standard HRC fuses for oil-immersed transformers. Meanwhile, our African partners prioritize the durability of our lightning arresters and drop-out fuses against harsh outdoor environments and lightning-prone regions.
Global procurement officers look for Stable Supply Chains and Technical Customization. Wenzhou Shuguang provides end-to-end service—from initial design blueprints to high-power testing validation. We understand that a fuse is not just a component; it is the last line of defense for multi-million dollar transformer assets.
By controlling the entire process—from raw material sourcing in the Yueqing electrical cluster to final assembly—we offer pricing that is significantly more competitive than Western counterparts without sacrificing quality.
Our engineering team can iterate on custom transformer fuse designs within weeks, whereas larger multinational corporations may take months. We thrive on "User Needs" and "Custom Production."
Our brand "Shu Rong" is synonymous with reliability. With a complete sales network covering all Chinese provinces and major international markets, our logistics and after-sales support are world-class.
In recent years, our company has developed rapidly, and its economic and social benefits have improved significantly. While vigorously developing new products, we have always attached importance to the process flow. High-quality raw materials and sophisticated testing equipment are the backing of our quality assurance system. All performance indicators are in line with the corresponding technical conditions, and new products can be customized and produced at any time according to user needs.
