FIELD: power engineering; overhead high-voltage power transmission lines installed on rugged terrain. SUBSTANCE: supporting structure has two poles and crossarms with current-carrying conductors attached to them through suspension insulator strings. Secured to each conductor by means of additional insulator string is respective guy which, in its turn, can be secured in ground by means of anchor device or on supporting structure. EFFECT: provision for using single-type intermediate poles with standard suspension insulators and traditional (triangular, vertical, horizontal, etc) arrangement of conductors throughout entire length of high-voltage power transmission line installed on rugged terrain. 7 dwg
