FIELD: erection of supports for power transmission lines. SUBSTANCE: single-circuit support has posts anchored in upper part and two cantilevers arranged on opposite sides of it to carry units for attachment of strings of suspension insulators of lower wires positioned in symmetry with regard to vertical axis of post. Third cantilever carrying unit for attachment of string of suspension insulators of upper wire is mounted in upper part of post at angle with vertical axis of post. Third L-shaped cantilever has vertically directed arm arranged at angle with vertical axis of post, unit for attachment of string of suspension insulators of upper wire is mounted on horizontally directed arm of this cantilever with arrangement of axis of string of suspension insulators on vertical axis of post. EFFECT: reduced usage of materials for manufacture of supports, decreased width of swath when power transmission line passes through woods. 2 cl, 3 dwg
