According to State Grid Sichuan Electric Power data, this earthquake has caused multiple power facilities to be damaged. KV lines, 5 110 kV lines. As of 18:00 on September 12, due to the severe damage to the tower and the high mountains, the mountains and high roads were difficult, and the construction of the dense forests was extremely difficult. The offline has not been seized, and the post -disaster reconstruction stage does not affect user power supply.

"Tower Gate -type rods were broken and severe deformation, and the guide line of Tower 19 to 20 was severely damaged ..." On September 8th, the State Grid Sichuan Sichuan Delivery Company responsible for the emergency repairs of 110 kV Tang The rescue team organically combined VR panoramic technology with the inspection of the transmission line through "manual inspection+drone flying patrol", relying on cloud production to form a continuous panoramic and multi -angle line inspection "digital" and "visualization" inspection map, quickly quickly, quickly quickly, quickly quickly, quickly quickly, quickly quickly, quickly quickly, quickly quickly, quickly quickly. Determined the damage defect that affects the operation of the line.

On September 12, according to the leader of the Sichuan Sichuan Sichuan Power Company Rescue Team, Yi Shi introduced that in order to accelerate the recovery of the line, State Grid Sichuan Electric Power requested the emergency support of the State Grid Space Technology Company, and completed the material transfer tasks of 30 people planned for 5 consecutive days in just 46 minutes. Subsequently, the rescue team insisted on safety first. It hikes for more than 7 hours a day. The construction station and operation site with a circular vertical height difference of more than 850 meters have been completed on the 15th. Series operation.

The next day, the 110 kV Tang went offline and passed the acceptance and recovered operation. At this point, State Grid Sichuan Electric has successfully restored the "9 · 5" Luding Earthquake Ganzi and Ya'an area to all damaged backbone transmission channels to provide strong power guarantees for the next earthquake -stricken reconstruction.
