China's largest 750-kilovolt (kV) ultra-high-voltage power transmission loop around the Tarim Basin in northwest China's Xinjiang Uygur Autonomous Region completed its first live-line working on April 29. The loop surrounds the Taklimakan Desert, the country's largest desert.

According to reports, during a routine inspection of the transmission lines, maintenance personnel identified a potential defect that could cause equipment failure. Subsequently, using a combination of drones and the "flying man" – a portable electric lifting device developed for high-altitude work and rescue – they reached the worksite and eliminated the defect within just one hour, without power interruption.
