Method for constructing compact double-loop overhead line by adoption of flying powered parachute

Provided is a method for constructing a compact double-loop overhead line by adoption of a flying powered parachute. According to the invention, a traction rope is unfolded by a flying powered parachute, and wires are unfolded under tension through one-pull-six of the traction rope, thus realizing erection of a high-voltage cable. By applying the method in construction, the construction period is shortened, the fee of compensation for young crops is reduced, the cost of human resources is reduced, the work efficiency is improved, and the comprehensive cost can be reduced by about half compared with manual guide rope unfolding. The method of the invention is applicable to power cable erection in remote forest areas and hilly areas.
