The global 187000 fuse and high-voltage circuit protection market is witnessing unprecedented growth. As nations modernize their aging electrical grids and transition toward renewable energy, the demand for reliable, high-specification fuses like the 187000 series has surged across Europe, North America, and Southeast Asia.
With the rise of massive solar farms and wind turbine networks, power technology is shifting toward decentralized energy systems. 187000 fuses play a critical role in safeguarding expensive power converters and energy storage systems from short-circuit faults, ensuring continuous power flow to the grid.
Modern industrial zones now demand "Smart Protection." The industry is moving toward components that not only break circuits but do so with millisecond precision. Our research and development focuses on maintaining strict thermal stability and arc-extinguishing capabilities required for these next-generation applications.
Located in Yueqing, Zhejiang Province—widely known as the Electrical Capital of China—Wenzhou Shuguang Fuse Co., Ltd. is a power technology enterprise integrating research, development, production, sales, and service. Established in 1992 as "Yueqing Shuguang Fuse Factory," we have grown over three decades into a pillar of China's high-voltage equipment sector.
We are designated by the Ministry of Electric Power Industry to produce high-voltage fuses across various voltage levels, including high-voltage current-limiting fuses, power capacitor fuses, voltage transformer protection, and zinc oxide arresters.
Our expertise is backed by rigorous testing and international compliance.
Our products have passed the high-power test station of the Electric Power Research Institute of the Ministry of Electric Power, the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center, and the Xi'an High-voltage Electrical Apparatus Research Institute.
The highest technical performance of our products meets: ANSIC37, 42, DIN43625, BS2692, IEC282-2-1995, IEC60644, IEC60470, IEC60282-1, IEC269-2 and national standards GB15166.1-5.
Our complete quality system ensures that every 187000fuse or arrester leaving our factory is ready for the most demanding environments, ensuring zero-defect performance in critical infrastructure.
In recent years, our company has developed rapidly, deepening the integration of AI-assisted design and automated manufacturing. We use high-quality raw materials and sophisticated testing equipment to back our quality assurance system.
Being located in Yueqing allows us direct access to the world's most dense electrical supply chain, reducing lead times and material costs without compromising on the high technical conditions required by BS or IEC standards.
We can customize and produce new products at any time according to user needs. Whether it's unique dimensions for the 187000fuse or specific current-limiting characteristics, our engineering team provides rapid prototyping.
Ensuring safety across diverse sectors with 187000 series solutions.
Backup protection for high-value oil transformers in urban distribution networks.
Specialized fuses for tail wire recovery and capacitor bank isolation.
Current-limiting protection integrated into modern vacuum circuit breaker units.
Protecting PV inverters and wind farm collector circuits from transient faults.
The "Shu Rong" brand products have enjoyed a high reputation among domestic and foreign users. Our products are exported to various provincial power companies in China, forming a complete domestic network.
Global Reach: Our high-voltage current-limiting fuses are exported to Southeast Asia, the Middle East, Africa, Europe, and beyond. We rank among the top in the industry for domestic sales and international export volume.
