INTERMEDIATE H-FRAME SUPPORT FOR HIGH-VOLTAGE POWER LINE

摘要

The utility model relates to intermediate supports for high-voltage overhead power lines, and can be used in the manufacture of supports for 330 kW and 500 kW power lines. The technical result is an increase in the rigidity and strength of the support, as well as an increase in its resistance to mechanical loads. The single-circuit intermediate H-frame power line support comprises two uprights (1, 2), each of which is comprised of three multi-sided steel sections (3, 4, 5) connected by flange joints (6, 7), and a composite cross-bar consisting of a crosspiece (8), hingedly fastened between the top sections (5) of the uprights, and two brackets (9, 10). The brackets are attached to the top sections of the uprights by means of flange joints (11, 12). The uprights are tied together by X braces (18, 19), and the top sections (5) are tied together by a tie rod (20). The brackets (9, 10) of the cross-bar are additionally fastened to the top sections (5) of the uprights by supporting rods (13, 14). The feet of the bottom sections (3) of the uprights are provided with flanges (21) for attachment to a foundation. The crosspiece (8) is additionally fastened to the top sections (5) of the uprights by supporting rods (16, 17).
