The line passes through Nanchang, Fuzhou and Yichun of Jiangxi Province and Changsha of Hunan Province, and Sunri Zhilian provides the fault monitoring solution for the Grade-3 galloping area of the line. With profound technical background and positive response speed, Sunri Zhilian completed the overall delivery of the project efficiently and reliably. The conductor galloping sensor adopts high-precision six-axis sensor chip, and sends the dynamic curve of galloping trajectory to the power background through the power APN private network, so as to realize the real-time monitoring of conductor galloping parameters on the UHV AC transmission line, which has met the application conditions of real-time monitoring and intelligent early warning of transmission line status.
