Definitions

  • the present invention relates to a conductor for a submarine energy cable, as well as to a method for manufacturing such a conductor.
  • a submarine energy cable consists essentially of one to three conductors wired with constant pitch and insulated, the whole being surrounded by armor made of steel wires laid in a helix.
  • the purpose of this armor is to protect the insulating layers and to increase the tensile strength of the cable.
  • the object of the invention is to obtain a lower tensile modulus than that obtained by heliocoidal wiring with constant pitch to reduce the force F 1 supported by the conductor.
  • the subject of the present invention is a conductor for an underwater energy cable, consisting of at least one layer of cabled metallic wires, characterized in that all the wires are wired in the same direction and at a periodically variable angle. As a result, all of the wires wind on either side of an average winding helix. Thus, during an elongation of the conductor, each conductor wire can follow this elongation by modifying its geometric position by approaching the mean helix without elongation of the wire itself.
  • the pitch of the ripple generated by the periodically variable angle is less than twice the average pitch of wiring.
  • the peak-peak amplitude of the undulation of the wires is less than 0.1 times the pitch of the undulation.
  • the present invention also relates to a manufacturing process, in which coils of wires are positioned in a cage, each wire is introduced into a distribution grid integral with the cage, then in a wiring die, the rotation is driven. cage and its distribution grid and the driver is driven in translation by means of a capstan, the rotation combined with the translation achieving a committing angle, characterized in that a periodic variation of the angle of committing.
  • the periodic variation of the angle of commetting is obtained by modulating the speed of rotation of the wiring qrille through which said wires pass.
  • the periodic variation of the angle of commetting is obtained by modulating the speed of the capstan which receives said wires.
  • the cage 1 is rotated from the main shaft 5 by means of a transmission comprising a gearbox 6.
  • a draft capstan 7 is also driven from the main shaft through a gearbox 8.
  • FIG. 2 shows the stranding machine equipped with a speed variation system ⁇ of the distribution grid.
  • a grid 9 is mounted which is driven independently of the cage by means of a transmission equipped with a gearbox 10 having ratios identical to those of the gearbox 6 of the cage.
  • a speed modulator 11 is added to the kinematic chain.
  • FIG. 3 shows the stranding machine equipped with a speed variation system v for drawing the capstan 7.
  • a speed variation system v for drawing the capstan 7.
  • the pitch of the wire ripple is p and the value of its peak-peak ripple is s.
  • P value is preferably less than twice the pitch of e g cabled means.
  • the value of- is chosen to be between 3% and 7%, which corresponds to a geometric elongation of the wires from 0.2% to 1%.
  • FIG. 5 shows an underwater energy cable comprising a single conductor composed of wires 50 according to the invention.
  • This conductor is surrounded by several insulating layers 51 which may be made of paper impregnated with oil, or of polyethylene or crosslinked polyethylene.
  • the layer 51 directly in contact with the conductor can be semiconductor to ensure a better distribution of the potential.
  • a weave 52 of steel wires surrounds the assembly.
