Definitions

  • the subject of the present invention is an electro-carrier cable, that is to say a conductor of electricity, in particular weak currents such as those which are intended to carry telecommunications, or more generally data, as well as to the supply of measuring or information processing equipment.
  • Such a power carrier cable has a significant weight capable of causing it to break under its own weight. This resistance / weight relationship is called the cable breakage in kilometers.
  • This cable weighs, in air, 680 grams / meter, and has a breaking strength of 9500 DaN; this cable suspended in the air will break under its own weight after:
  • US-A-4 034 138 discloses an electromechanical cable with low density and high resistance including multifilament fibers of aromatic polyamides covered with a protective coating of polyurethane intended to prevent the self-abrasion of aramid fibers.
  • the conductive wires extend parallel to the carrier fibers and have an elongation less than that of the reinforcing elements.
  • EP-A- 0 054 784 relates to a telephone cable in which the carrying elements consist of aramid fibers in the form of a central core and strands wired with the conductors.
  • DE- A-3 241 425 relates to a conductive cable whose central conductive elements are surrounded by an aramid reinforcement braid which constitutes the carrier element.
  • An object of the present invention is an electrically conductive cable which is light, and the conductive part of which can only break when a mechanical rupture of the carrying elements of the cable has already occurred.
  • the cable reinforcing elements break before the conductor (s). These, in the event of a cable break, are only requested as late as possible, and after the carrier element has itself failed.
  • the electrically-carrying cable comprising electrically conductive elements and insulating elements of aramid mechanical reinforcement included in an extruded sheath
  • the conductive elements are integrated in an elastic central core, surrounded by a reinforcement of aramid fibers and a sheath
  • the elastic central core comprising an insulating central core on which are insulated insulating core cores, the conductors being wrapped on a carrier core stranded with the inserts so that the length of the conductors is greater than the length souls, itself greater than the length of the reinforcement.
  • the elastic core consists of a central core composite of twisted fibers. Around this core are arranged, as tightly as possible, in a helix, two or more conductors forming a homogeneous strand.
  • the elementary electrical wires are wrapped on a core, generally made of high modulus aramid, with contiguous turns and with tight pitch.
  • a core generally made of high modulus aramid
  • the strands are not stressed in tension, they can be made of a material without particular physical properties.
  • the sheathing of the electrical conductors will preferably be made of insulating resin with a low coefficient of adhesion such as fluorinated products.
  • the direction of twist of the electrical conductors and / or the spacers are opposite to the direction of stranding of the core, in order to obtain an anti-gyratory effect.
  • the high-modulus fiber reinforcement, or carrier element can be made up according to different formulas such as braiding or cable technique.
  • the braid is preferably constituted for example by aromatic polyamide fibers, which have the advantage of having a very low elongation, and of being as resistant as steel wires for a weight fifteen times less. in water These fibers can be coated with a protection.
  • the braid must be made, imperatively, with a long pitch, with a braiding angle equal to or less than 15 °, to limit its elasticity as much as possible.
  • such fibers have the advantage, especially for application to oceanography, of being electrically insulating, which avoids the problems of parasitic conduction, the chemical inertness of the material eliminating the problems of corrosion.
  • a thin film for example made of polyurethane, which ensures cohesion of the assembly, and prevents the core from sliding relative to the support element. , when working the cable.
  • the protective sheath is generally extruded in an elastomeric material preferably, such as polyurethane for example.
  • the sheath does not play any role in tensile strength, but it aims to protect the load-bearing element and the elastic core against abrasion, and more generally, against environmental aggressions.
  • a central core 1 which, as indicated above, consists of twisted aramid fibers and secured by polyurethane.
  • conductors 2 and / or spacers 2a which, in the example shown, are six in number. These are twisted in a tight pitch and, for example in a pitch of 32 mm for a diameter of 4.7 mm from the elastic core.
  • the spacers are advantageously constituted by aramid fibers integrated in a polyurethane matrix.
  • the electrical conductors constituted by a core 8 on which is wrapped one, but preferably several metal wires 7 coated with a thin layer of Teflon 5 (Fig. 3) or other fluorinated product intended to allow relative sliding of the conductors 2.7 and spacers 2a relative to each other during work.
  • the directions of twist of the electrical conductors and / or the spacers are opposite in order to obtain an anti-gyratory effect.
  • the elementary electrical wires advantageously made of copper or a copper alloy, are wrapped in contiguous turns and with tight pitch on a carrier core 8, generally made of high modulus aramid.
  • the fluorinated sheath 5 ensures good sliding of the conductors and spacers with respect to each other.
  • Braid 3 is a "flock" braid, made up of aramid filaments. It is imperatively carried out with a long pitch (braiding angle less than 15 °). It ensures the tensile strength of the cable.
  • aromatic fibers have a very low elongation at break (from 2 to 4%), so that they resist the forces applied at the ends of the cable before the voltage is transmitted to the elementary electrical wires.
  • the sheath 4 made of polyurethane, does not play any role in the tensile strength, but it aims to protect the braid against abrasion and, more generally, against environmental aggressions.
  • the cable thus obtained has a weight of 140 grams / meter. It has a breaking strength of 7,800 decanewtons and its 100 cm breaking in air is 56.
