Located in Yueqing, Zhejiang Province, known globally as the "Electrical Capital of China," Wenzhou Shuguang Fuse Co., Ltd. stands as a beacon of excellence in the power technology sector. We are a specialized power technology enterprise integrating intensive research, development, high-precision production, and a robust global sales service network.
The legacy of our expertise dates back to 1992, when our predecessor, "Yueqing Shuguang Fuse Factory," was established. For over three decades, we have remained committed to the evolution of circuit protection technology, ensuring that modern electrical grids remain safe and resilient against overcurrent and short-circuit faults.
As a leading China BestStandardFuses Supplier, our mission is to deliver engineering precision to every transformer, substation, and industrial power line we protect.
The demand for high-voltage and medium-voltage fuses is surging worldwide. With the rapid electrification of the global economy, the need for reliable protection in power distribution networks has never been more critical. Industrialized nations and emerging markets alike are upgrading aging infrastructure to support higher loads.
The rise of solar farms, wind energy, and Electric Vehicle (EV) charging infrastructure requires specialized fuse links. Standard fuses must now handle the unique oscillating loads of renewable generation while maintaining high breaking capacity to protect expensive inverter systems.
Miniaturization and "Smart Grid" compatibility are the leading trends. Modern fuses are designed with tighter tolerances, utilizing advanced silver-element technologies and high-grade ceramic bodies to ensure faster interruption and higher thermal stability in extreme environments.
Quality and reliability are not just slogans; they are verified by global testing bodies. We are designated by the Ministry of Electric Power Industry to produce high-voltage fuses of various voltage levels, including:
Our products have passed rigorous testing at the Electric Power Research Institute of the Ministry of Electric Power and the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center. We strictly adhere to:
As a leading China factory, we control the entire process from raw material selection to final testing. This integration allows for superior quality control and competitive lead times compared to Western suppliers.
Every grid is unique. We provide customized solutions tailored to specific user needs, whether it's specialized current ratings for medium voltage DIN standard back-up fuse-links or custom dimensions for aging substations.
Our location in Yueqing provides us with immediate access to a world-class electrical component ecosystem. This ensures that even during global logistics fluctuations, we maintain a steady output of high-reliability fuses.
With three decades of data from high-power test stations and field performance across Southeast Asia, Europe, and Africa, our technical team possesses the deep domain Expertise required to consult on complex protection coordination. Our Authority is backed by ISO9001:2000 certification and strict compliance with IEC standards, ensuring Trustworthiness in every shipment.
In recent years, the company has developed rapidly, improving economic and social benefits through continuous innovation. We have never ceased our long-term development of the quality management system. 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 corresponding technical conditions. Our "Shu Rong" brand products have enjoyed a high reputation among domestic and foreign users for their precision and longevity.
