ABSTRACT:
An overhead power transmission line formed by stranding at least one outwardly projecting strand at the outermost layer of an overhead power transmission line formed by a plurality of strands. At least the outwardly projecting portion of the outwardly projecting strand is composed of an organic material. The outwardly projecting strand has a projection height H within a range defined as 1.5 mm.ltoreq.H.ltoreq.7.0 mm. By setting the projection height H of the outwardly projecting strand equal to or larger than 1.5 mm, the wind noise characteristic can be conspicuously improved. Further, by setting H.ltoreq.7.0 mm, the outwardly projecting strand comprised by an organic material is made easily crushable, so the gripping portions of spacers, dampers, and other parts which have been conventionally used can be used as they are.
