On October 7, the Electric Power Research Institute of State Grid Fujian Electric Power Co., Ltd. applied new technology of high-altitude UAV-based radiographic testing to inspect the crimped connection of 16 tension clamps for the Fuzhou-Xiamen 1000 kV UHV AC project. Compared with manual inspection that requires climbing up the power tower, this new technology reduces the average time of inspection to less than 10 minutes and increases the efficiency by about 6 times.
