FIELD: electrical engineering. ^ SUBSTANCE: overhead line anchor angular support comprises a leg with its one end attached onto load bearing surface and its top supporting spaced apart various-height braces for power line wires to be suspended thereon, and line guys with their one ends anchored in aforesaid load bearing surface. Strain strings of two top wire phases are fastened to upper crossarms. Two opposed braces are attached to aforesaid leg, perpendicular to said crossarms, to fasten other ends of said line guys. Note here that aforesaid two braces are located above tension string support attached to the leg and crossarm intended for lower phase loop leading around. Note also that line guys are arranged in a three-beam-start pattern, every start beam being formed by two line guys. One ends of the latter are connected to appropriate common anchor. The other end of one line guy in a beam is fastened to one brace, while the end of the othero line guy is fastened to the other brace. ^ EFFECT: reduced metal input, higher reliability in severe operating conditions. ^ 2 dwg |
