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 is essentially made up of one to three conductors wired at 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 helical 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 wired metal wires, characterized in that all the wires are wired in the same direction and at a periodically variable angle.
- each conductor wire can follow this elongation by modifying its geometrical 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 characterized in that a periodic variation of the angle of commettage.
- the periodic variation of the angle of commetting is obtained by modulating the speed of rotation of the wiring grid 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 driven in rotation from the main shaft 5 by means of a transmission comprising a gearbox 6.
- a drawing 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 w 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 modulator 12 is added.
- the pitch of the wire ripple is p and the value of its peak-peak ripple is ⁇ .
- the value of p is preferably less than twice the average wiring pitch.
- the value of is chosen 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.
