[China's First 2-Ton Load-Bearing Tethered Balloon Put into Trial Operation] Today, China's first 2-ton load-bearing tethered balloon was put into trial operation on the Tibet-Guangdong DC transmission project. As the construction of new power grids accelerates its extension to high-altitude, deep mountainous, and ecologically sensitive areas, the transportation of materials for power transmission projects has become a major challenge for construction. Traditional road construction transportation methods are time-consuming and cause significant ecological disturbance. While drones are flexible, they still have limitations in scenarios involving heavy loads and long-term continuous transportation. Tethered balloon transportation technology effectively overcomes these limitations. (CCTV)
