Open the foldable wings, tap the button, and in just over 10 minutes, a power line inspection work across the factory area was successfully completed. In the past, it took workers more than 4 hours to complete this work. Our company's energy power plant has introduced drone technology into the inspection of high-voltage transmission lines, which has improved work efficiency and reduced the cost of power grid operation and maintenance. The "thousand-mile line inspection" of employees has become a thing of the past. The picture shows that the workers of the factory are operating drones for line inspection.
