FIELD: ground construction.
SUBSTANCE: invention relates to double-console crossarms of single-column supports of power transmission lines (PTL). Crossarm of support of power transmission line has the shape of U-beam made of layered composite material, on the ends of which in the flanges there made are coaxial holes for pins with insulators for attachment of power line wires, and between the flanges spacers are installed, in which there are rods fixed on both sides of the beam using a metal plate bracket, and in the middle of crossarm there are two holes at the distance equal to thickness of support column, for attachment of crossarm on pillar of support by mounting bolts. Also, a crossarm version and versions of the cross beam attachment method to the single-column support of power transmission lines are described.
EFFECT: technical result is higher reliability of power transmission tower supports.
