FIELD: transportation.
SUBSTANCE: invention relates to a conductor line of a U-shaped cross-section wherein on the side walls limiting the mounting channel (2) carrier bus bars (3) of insulating material are placed, on which several bare electrical wires (5, 6, 7, 8) isolated from each other and accessible on the mounting channel side are fixed, three of which are connected as phase and one - as neutral, and it is proposed to place between the wires of the corresponding pair of wires fixed in the carrier bus bar (3) the fifth and sixth bare wires (10, 11), isolated from pairs of wires which are opposite each other and accessible on the mounting channel (2) side and which are connected as controllers.
EFFECT: in addition to working in a three-phase mode, it is possible to connect additional electrical consumers or transmit signals.
