State Grid Dingxi enhances power line maintenance for Spring Festival

During this year's Spring Festival, State Grid Dingxi Power Supply Company carried out specialized inspections on key transmission lines and corridors.

Operation personnel took advantage of the increased movement during the holiday market season to promote awareness of wildfire and external damage prevention, contributing to the stable operation of the local power grid.

The company prioritized the Spring Festival power supply task and organized its efforts around ensuring reliable electricity for local residents.

A structured maintenance approach was adopted, with clear assignments for each tower, identified risks, and specific duties assigned to personnel.

Inspectors used infrared thermography devices to check conductor fittings and connectors. They also inspected tower foundations and checked for loose coverings in nearby agricultural areas to prevent electrical faults.

Digital tools played a key role in monitoring. The company strengthened remote video surveillance of essential transmission lines, enabling real-time tracking of equipment status and environmental changes around protected zones.

A hybrid inspection model combining visual monitoring with ground patrols was implemented. For key 330 kV and 110 kV lines, the company conducted online monitoring and deployed personnel for on-site observation.

Drone technology was also widely used. Unmanned aerial vehicles worked alongside ground teams to inspect major power supply lines. These drones conducted autonomous patrols, performed infrared temperature checks, and used positioning systems for thorough and frequent oversight.

The company made reliable power supply its main focus during the holiday. It enhanced monitoring across all transmission lines and reinforced emergency response preparations.

Teams, vehicles, tools, and spare parts were readied, and a duty system was strictly followed to ensure uninterrupted power throughout Spring Festival.
