With spring plowing getting underway and key projects fully resuming, the risk of external damage to power lines has entered a high-incidence period. The State Grid Xiantao Power Supply Company has steadily advanced various external damage prevention measures to ensure the safe and stable operation of the power grid.

The company organized staff to go deep into the fields across the city, issuing power facility protection notices to the operators of 1,184 rotary cultivators and 229 large agricultural drones. They explained on-site the precautions for maintaining a safe distance from power lines during mechanical operations. Simultaneously, they issued targeted reminders to groups such as crane operators and reposted over 180 reminder signs.

Focusing on key projects such as the "four-to-eight-lane" expansion of the Shanghai-Chongqing Expressway, the State Grid Xiantao Power Supply Company conducted a blanket inspection of 15 affected transmission lines, 35 cable trenches, and 37 transmission towers. They signed safety hazard notices with relevant parties along the routes and verified on-site protective measures. At the same time, the company completed a full inspection of 33 key hazard points on 110 kV transmission lines, cleared tree obstacles in urban and densely populated areas, and eliminated 29 hazards caused by overgrown trees, ensuring that the line corridors remain unobstructed.
