It is our job to solve the electrical contact overheating failure, and it is our ultimate goal to completely eliminate the electrical contact overheating accident.

In more than 40 years of production practice, after hundreds of times of handling and solving electrical contact overheating fault accidents, and after repeated inspections and explorations from practice to theory, senior technicians in substation maintenance have been appointed, continuously developed and improved: The electrical contact (joint) temperature is lower than the conductor (line) by more than 5%, which is the theory and technology of "not overheating electrical contacts", and the trademarked "not overheating electrical contacts" developed by this theory and technology. "Firmware" series, new patent number ZL200920080297.1; high current overheating electrical contact special fastener series (conductive bolt rod-national standard 149 threaded terminal) patent number 200920080298.6; and the patent number of trouble-free drop wire 20070078414.4 and other electrical equipment, participated in the Fifth Beijing (05) and Guangzhou Sixth (07) International Conference on Transmission and Distribution Technology, and was strongly recommended and affirmed by experts from the China Electricity Council and the Organizing Committee (detailed (See Ren Yi website)

has been promoted in Beijing, Tianjin, Chongqing, Guangzhou, Henan, Hebei, Shanxi, Sichuan and other provinces and cities, and has achieved good safety benefits, economic benefits and social benefits during many years of "online" operation.
