Xiaogan Power Supply Company Conducts Firefighting Drill with Drones Ahead of Qingming Festival

Ahead of the Qingming Festival, Xiaogan Power Supply Company simulated the scene of a sudden wildfire threatening the safe operation of transmission lines and innovatively adopted a "three-dimensional combat system" to control the fire.

In the air, heavy-duty drones accurately dropped fire-extinguishing bombs to suppress the "fire source," while inspection drones and visual monitoring equipment provided real-time surveillance of the fire’s spread. On the ground, line inspection personnel built defensive lines using pneumatic extinguishers, dry powder extinguishers, and firebreaks. Meanwhile, at the command center, the transmission monitoring team leveraged a new-generation remote intelligent inspection system to implement a closed-loop management process encompassing "disaster modeling, intelligent analysis, precise dispatching, and effectiveness evaluation."

During the drill, a drone equipped with a small payload release system dropped fire-extinguishing bombs, quickly bringing the "fire" under control. "Drone-based firefighting is highly maneuverable and not limited by terrain, making up for the deficiencies of traditional manual wildfire suppression, which is often difficult and inefficient," explained Zhao Zilong, an employee of Xiaogan Power Supply Company.

Up to now, Xiaogan Power Supply Company has established 121 power supply protection teams and deployed 384 vehicles. It has completed patrol inspections of 70 densely forested 10 kV power lines and 158 key transmission lines of 110 kV and above in mountainous areas such as Dawu and Xiaochang. Special attention has been given to 60 Qingming Festival sacrificial sites, with personnel assigned for on-site monitoring and hazard identification.
