Overhead power transmission line
The invention discloses an overhead power transmission line and belongs to the field of power equipment. The overhead power transmission line at least comprises a first tower, a second tower, a third tower, a ground wire and a lead wire, wherein the first tower, the second tower and the third tower are arranged on ground foundations respectively, the second tower is positioned between the first tower and the third tower, and the position of the ground foundation where the second tower is positioned is lower than those of the ground foundations where the first tower and the third tower are positioned. The overhead power transmission line has the advantages that by means of arranging an insulator string of the second tower on a lead wire cross arm of the second tower, during use, the first tower and the third tower generate bilateral pull-up acting force on the second tower through the lead wire, and then the second tower tensions the insulator string of the second tower through the bilateral pull-up acting force on the lead wire to enable that blowing lead wire by wind has little effect on a safe distance between the lead wire and a tower body of the second tower, so that substituting tension-resisting towers for tangent towers in a mountainous area large in altitude difference is avoided, and production cost for the overhead power transmission line is reduced.
