Shu Guang
Wenzhou Shuguang Fuse Co., Ltd., located in Yueqing, Zhejiang Provinceβthe renowned electrical capital of Chinaβis a premier power technology enterprise. We integrate professional research, development, production, sales, and comprehensive service. Our roots trace back to the "Yueqing Shuguang Fuse Factory" established in 1992. Over the decades, we have evolved into a global leader in high-voltage circuit protection.
As a leading China GZHVfuse supplier, we have dedicated over 30 years to perfecting the art of electrical safety. Our expertise spans across various voltage levels, ensuring that global power grids remain stable and resilient under all conditions.
The global shift toward Smart Grids requires high-voltage fuses that offer precision and digital compatibility. Modern GZHVfuse products are now designed to integrate with monitoring systems to provide real-time status updates in substations.
With the surge in Solar and Wind energy, there is an unprecedented demand for specialized fuses. Current-limiting fuses are critical for protecting expensive inverters and transformers from transient faults in volatile weather conditions.
Electric Vehicle charging stations require high-reliability protection. As a specialized manufacturer, we produce EV-specific fuses that handle high DC voltages, ensuring safety for the next generation of transportation.
The global high-voltage fuse market is projected to grow significantly as aging infrastructure in North America and Europe is replaced, and rapid urbanization in Asia and Africa continues. The trend is moving towards environmentally friendly materials, higher breaking capacities, and smaller physical footprints. At Wenzhou Shuguang Fuse Co., Ltd., we are at the forefront of this transition, utilizing silver-plated fuse elements and high-grade quartz sand to enhance thermal stability and quenching capabilities.
We are designated by the Ministry of Electric Power Industry to produce high-voltage fuses, current-limiting fuses, capacitor fuses, and zinc oxide arresters. Our technical performance meets ANSI C37.42, DIN 43625, BS 2692, and IEC 60282 standards.
Products have passed rigorous testing at the Electric Power Research Institute, National High-voltage Electrical Apparatus Quality Supervision Center, and Xi'an High-voltage Research Institute. Reliability is our core promise.
Our company's quality assurance system is complete, certified under ISO 9001:2000. We ensure every product leaving our factory meets the highest international quality benchmarks.
International buyers seek suppliers who can handle bulk orders with consistent quality. Our factory in Yueqing offers the capacity to supply state-level utility projects and private industrial plants across Europe and the Middle East.
From the humid coastal regions of Southeast Asia to the high-temperature environments of the Middle East, our GZHVfuse products are engineered with anti-corrosion and heat-resistant materials to perform in any climate.
We help procurement officers reduce the Total Cost of Ownership (TCO) by providing durable fuses that reduce maintenance frequency and prevent catastrophic equipment failure during short-circuits.
Located in the heart of China's electrical hub, we benefit from a mature supply chain that allows us to source high-purity raw materials at competitive rates. This translates to cost savings for our clients without compromising on safety. Our "Shu Rong" brand has built a prestigious reputation for being a reliable partner in the electric power industry.
We strictly adhere to the principle: "Development by science and technology, and survival by quality". Whether it is a standard DIN fuse or a customized solution for a specific industrial application, our engineering team is ready to deliver.
