Today, the first domestic 2-ton heavy-duty tethered balloon was put into trial operation at the Tibetan-Guangdong DC Project. As construction of new power grids accelerates and extends to high altitudes, deep mountains, and ecologically sensitive areas, material transportation for transmission projects has become a problem limiting construction. Traditional road construction has a long transportation cycle and great ecological disturbance. Although drones are flexible, they still have limitations in scenarios such as heavy loads and continuous transportation for a long period of time. Tethered balloon transportation technology has effectively solved these limitations.
