摘要

FIELD: transport.;SUBSTANCE: proposed configuration includes: line towers, brackets for attachment of two insulators in line at base angles of imaginary spatial equilateral triangle with sides increased to minimum tolerable convergence.; For balancing said linear electric parameters, six-step cross bonding of wires-phases is used with wire-phase turn through 60° at every tower and gyration of wires over entire length of the line. Geometrical arrangement of wires at said towers at angles of imaginary spatial equilateral triangle is performed by means of alternating-height different-length brackets with suspended insulators for wires-phases to be secured thereat.;EFFECT: reduced electromagnetic interferences.;2 dwg
