The corridor is 520 kilometers long, traversing complex terrain including mountains, hills, and rivers. Traditional manual

Since 2024, the power company has adopted a “multi-machine collaboration + intelligent analysis” inspection model, deploying 6 industrial-grade drones equipped with high-definition visible light cameras, infrared thermal imagers, and lidar to achieve autonomous inspection of the entire line.
