FLEXIBILITY-IMPROVED CENTRAL TENSILE MEMBER FOR OVERHEAD TRANSMISSION CABLE, AND OVERHEAD TRANSMISSION CABLE INCLUDING SAME

WIPO Patent Application WO/2023/121359

A1

The present invention relates to a flexibility-improved central tensile member for an overhead transmission cable, and an overhead transmission cable including same. In particular, the present invention relates to a flexibility-improved central tensile member for an overhead transmission cable, and an overhead transmission cable including same, wherein the central tensile member has excellent tensile strength and thus has excellent sag properties preventing the wired overhead transmission cable from sagging, and has sufficient flexibility and thus improves wiring workability. Moreover, the central tensile member can suppress corrosion and damage to a conductor wire arranged around the central tensile member and thus can eliminate or minimize an increase in resistance of the overhead transmission cable, as well as a resultant reduction in transmission capacity, and makes it possible to reduce weight and manufacturing costs of the overhead transmission cable.
