A helicopter construction method of a power transmission line using an ultra high molecular weight poly-ethylene rope is provided to reduce the number of helicopter flights by doubling the length of a stranded wire in construction of the power transmission line through a helicopter. A helicopter construction method of a power transmission line using an ultra high molecular weight poly-ethylene rope(10) includes the steps of: installing a drum space and an engine space before and behind a power transmission tower(30) according to a construction plan; installing pulleys(11) in a steel tower reinforcing unit after installing a protection foothold to install a stranded wire in the power transmission tower; installing the ultra high molecular weight poly-ethylene rope in the power transmission tower by connecting a strander(40) to a helicopter(20) after winding the rope around the strander; installing a wire rope in the power transmission line by connecting the wire rope to an end of the installed ultra high molecular weight poly-ethylene rope to strand the ultra high molecular weight poly-ethylene rope through the engine space; installing the power transmission line in the power transmission tower by connecting the power transmission line to one end of the installed wire rope to pull the wire rope through the engine space; and finally inspecting the power transmission line after fixing the power transmission line installed in the power transmission tower through a fixing unit. |
