Abstract

A multiple-cable power transmission line system is provided which includes a plurality of overhead transmission lines each having a ridge on the outer periphery thereof. When the outer periphery-to-crest height of the ridge of an overhead transmission line which is located closer to the earth ground is LE and the outer periphery-to-crest height of the ridges of the other overhead transmission lines is L.sub.OT, the relation L.sub.E <L.sub.OT is fulfilled.
