Central Tension Line For Overhead Power Transmission Cable Having Damage Detection Function And Overhead Power Transmission Cable Comprising Same

Abstract: The present invention relates to a central tension line for an overhead power transmission cable having a damage detection function and an overhead power transmission cable comprising same. Specifically, the present invention relates to a central tension line for an overhead power transmission cable having a damage detection function and an overhead power transmission cable comprising same, wherein: it is possible to easily and accurately detect whether the central tension line is damaged immediately before installing the overhead transmission cable on a pylon or immediately before clamping for the installation of the overhead transmission cable, as well as after installing the overhead transmission cable on the pylon; and the central tension line has excellent tensile strength, thus having excellent sag properties preventing the wired overhead transmission cable from sagging, and has sufficient flexibility, thus improving wiring workability, while the central tension line can suppress corrosion and damage to a conductor wire disposed around the central tension line, and thus can eliminate or minimize an increase in the resistance of the overhead transmission cable and the resultant reduction in transmission capacity, and enables the weight and manufacturing costs of the overhead transmission cable to be reduced.
