——Professionally manufacturing fuses for 33 years——
WENZHOU SHU GUANG FUSE CO.,LTD. is located in Yueqing, Zhejiang Province, the electrical capital of China.is a power technology enterprise integrating research, development, production, sales and service. The predecessor of Wenzhou Shuguang Fuse Co., Ltd. was "Yueqing Shuguang Fuse Factory" established in 1992. 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. product,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,All performance tests are qualified.The highest technical performance meets the ANSIC37,42、DIN43625、BS2692、IEC282-2-1995、IEC60644、IEC60470、IEC60282-1、IEC269-2和GB15166.1、GB15166.2、GB15166.5、GB13593、DL/T640-1997、VDE0636 standard and related technical conditions, our company's quality assurance system is complete, and it has passed IS09001: 2000 quality system certification. In recent years, the company has developed rapidly, and its economic and social benefits have improved significantly. The company continues to deepen and improve the quality management system, and has never exceeded its long-term development. 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. 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. "Shu Rong" brand products have enjoyed a high reputation among domestic and foreign users. The products are exported to various provincial power companies in China. A complete sales network has been formed throughout the country, and good business contacts have been established. New high-voltage fuses and high-voltage current-limiting fuse products are exported to Southeast Asia, the Middle East, Africa, Europe and other countries and regions, and the domestic product sales rank among the top in the same industry.

1. On-site phenomenon:
1. There is a car wash outside the wall of the power station, and there is a lot of water vapor. There are fan holes on the wall of the power station that communicate with the car wash (but the wind is blown out from the substation).2024-09-11
Fuse refers to an electrical appliance that fuses the fuse with the heat generated by itself and disconnects the circuit when the current exceeds the specified value. The fuse is based on the fact that after the current exceeds the specified value for a period of time, the heat generated by itself melts the melt, thereby disconnecting the circuit; a current protector made by using this principle. Fuses are widely used in high and low voltage power distribution systems and control systems, as well as electrical equipment. As short circuit and overcurrent protectors, fuses are one of the most commonly used protection devices.2024-09-11

XRNT is generally used to protect transformers, and XRNP is generally used to protect transformers. XRNT’s fusion tubes have relatively large currents, and XRNP’s have small currents such as 0.5A or 1A. The commonly used specifications are different. The size of the fusion tube is also different , The matching seat is also different, the XRNT one is bigger. The fuse tube of XRNP is relatively small.2024-09-11
