The invention can be used in the production of prestressed reinforcement. The problem of interest consists in developing a reinforcing cable having an increased degree of bonding, said cable having guaranteed structural stability and providing an increased degree of bonding with concrete, durability, and stress relaxation resistance. In a reinforcing cable, a central wire (1) is disposed along the axis of the cable, and is configured with spiral grooves (2) having a pitch that is equal to the pitch of the lay of the cable. Strand wires of an inner layer are disposed within the grooves, each of said wires being in contact with the central wire and with two adjacent wires of the inner layer. Strand wires are helically arranged at equal intervals from one another in an outer layer, each of said wires being disposed in a groove between the strand wires of the inner layer, and being in contact with the latter.
A reinforcing cable having an increased degree of bonding, consisting of a central wire and strand wires helically arranged around it in two concentric layers, wherein spiral grooves are provided on the central wire in the direction of the cable lay with a pitch equal to the pitch of the cable lay, and the strand wires of the inner layer are disposed in these grooves and each of them contacts the central wire and two adjacent strand wires of the inner layer, and the strand wires are helically arranged at equal intervals from one another in the outer layer, each of said wires being in contact with two, adjacent strand wires of the inner layer, between which it is disposed in the groove.
