As a leading Surge Arrester Manufacturer & Factory serving the Nagoya region, we understand that Aichi Prefecture is the industrial heartbeat of Japan. From the massive automotive assembly lines of Toyota City to the aerospace hubs near Chubu Centrair International Airport, Nagoya's industrial landscape demands absolute electrical reliability.
Nagoya's unique geography, nestled between the Pacific coast and the Central Japanese Alps, makes it prone to seasonal lightning storms that can cripple smart factories. A single micro-surge can cause millions of yen in downtime for robotics and CNC machinery. Our Zinc Oxide Surge Arresters are specifically engineered to withstand the rigorous demands of Nagoya's "Monozukuri" (craftsmanship) culture, ensuring that power distribution networks remain resilient against atmospheric overvoltages.

Wenzhou Shuguang Fuse Co., Ltd. is located in Yueqing, Zhejiang Province, the electrical capital of China. As a power technology enterprise integrating research, development, production, sales, and service, we bring global expertise to every Surge Arrester we manufacture. The predecessor of Wenzhou Shuguang Fuse Co., Ltd. was "Yueqing Shuguang Fuse Factory" established in 1992.
Over three decades, we have evolved from a local manufacturer into a global powerhouse, providing essential protective components to markets as demanding as Nagoya, Japan. Our commitment to quality is the bridge that connects our manufacturing excellence with the high standards of the Japanese industrial sector.
The modern surge arrester is no longer a passive component. In Nagoya's smart factories, we are seeing a shift towards surge arresters with integrated leakage current sensors and IoT connectivity for predictive maintenance.
With Nagoya leading the EV revolution, protecting high-speed DC charging stations is critical. Our arresters are optimized for the transient profiles of electric vehicle supply equipment (EVSE).
Nagoya's push for solar integration on factory rooftops requires specialized DC surge protection. We provide Class I and Class II coordination to protect sensitive inverters.
It is designated by the Ministry of Electric Power Industry to produce high-voltage fuses of various voltage levels, high-voltage current-limiting fuses, high-voltage fuses for power capacitors, voltage transformer protection fuses, zinc oxide arresters, drop-out fuses, high-voltage insulators, etc. The 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, the Xi'an High-voltage Electrical Apparatus Research Institute, and the High-Voltage Electrical Apparatus Laboratory.
The highest technical performance meets: ANSIC37, 42, DIN43625, BS2692, IEC282-2-1995, IEC60644, IEC60470, IEC60282-1, IEC269-2 and GB15166.1, GB15166.2, GB15166.5, GB13593, DL/T640-1997, VDE0636 standards.
Protecting signaling systems and substations for the dense rail network surrounding Nagoya Station from lightning-induced transients.
Salt-fog resistant surge arresters for gantry cranes and terminal automation systems in Japan's busiest port by cargo throughput.
Ensuring ultra-precise robotics fabrication lines in the Chubu region are shielded from high-energy surge events that can corrupt sensor data.
While we serve the specialized needs of Nagoya, our products are exported to various provincial power companies in China and established networks worldwide. New high-voltage fuses and current-limiting fuse products are exported to Southeast Asia, the Middle East, Africa, and Europe.
The company continues to deepen and improve the quality management system. While vigorously developing new products, it has always attached importance to the process flow. High-quality raw materials and sophisticated testing equipment are the backing of the quality assurance system. "Shu Rong" brand products have enjoyed a high reputation among domestic and foreign users.
