Definitions

  • the present invention relates to a tensile armor for cables and a cable for underwater use provided with such armor, in particular a so-called umbilical cable for scuba diving habitats.
  • cables subjected to significant tensile forces are provided with a metallic tensile armor.
  • these metallic armours are too heavy for a given tensile strength, and they are then replaced by armours composed of aramid fibers. These fibers are wound on the active core of a cable, whether contiguous or not, in one or two layers, then covered by a hooping sheath.
  • Document FR-A-2,402,283 discloses an umbilical cable provided with a tensile armor in which the fibers are held in elements of rectangular section, connected together by a socket engaging in a groove of the adjacent element to form a continuous armor over the entire circumference of the cable.
  • the rectangular section of these elements has several major drawbacks, because the armor thus formed does not constitute a self-locking system and it only forms a vault structure if the cable is subjected to a maximum tensile force.
  • umbilical cables are not only subjected to pure tensile forces but also to twists, and this cable of the prior art has poor resistance to lateral stresses due to these twists.
  • the present invention aims to eliminate these drawbacks by proposing a tensile armor composed of self-locking elements which form a vault structure even under low traction, and all kinds of cables provided with an armor according to the invention have good resistance. lateral stresses due to torsion.
  • the present invention relates to a tensile armor for cables, consisting of identical elements of great length fitting edge to edge over the entire circumference of a cable and each provided in its central part with at least one fiber, in particular metallic or aramid, characterized in that each element comprises at each edge a lip of substantially circular shape attached to the central part by a gutter defining a free space receiving a lip of an adjacent element.
  • each element comprises in its central part two beads substantially closing the two free spaces defined by the gutters, each free space having the same shape as a lip but in the opposite direction to receive by snap-fastening a lip of an adjacent element. ''
  • each lip is reinforced with a metallic or aramid fiber and each element has longitudinal grooves.
  • one lip of an element is located on the inside of the armor while the other lip is located on the outside, each element then being placed in the same direction.
  • the two lips of an element are located on the same side, one element out of two then being placed in the opposite direction.
  • the present invention also relates to an undersea cable using two armor as defined above.
  • FIG 1 there is shown in section, only one sector of an armor 10 where we see some elements 11, connected to each other. For clarity, a single element 11 is shown in section.
  • Each element 11 consists of a central part 12, and of each side of this central part, two lips, an inner lip 13 and an outer lip 14.
  • the central part 12 comprises two fibers 16, for example metallic or aramids of the "KEVLAR" type, and two beads 15.
  • Each lip 13, 1 i j is of substantially circular shape and between a bead 15 and each lip 13, 1ij there remains a gutter 19 defining a free space receiving by snap-fastening the lip of an adjacent element.
  • the material of each element (polypropylene or nylon for example) is flexible enough to allow this snap.
  • the lips 13, 14 have in their center a fiber 17, for example metallic or aramid and each element also has six grooves 18, four grooves in the central part, two of which on each face, and a groove on each lip. These grooves allow better attachment of the sheaths contiguous to this armor.
  • FIG 2 there is shown in section only a sector of armor 20 where we see some elements 21 connected to each other. For clarity, a single element 21 is shown in section.
  • Each element 21 consists of a central part 22 and on each side of this central part of two lips 23, the two lips being located on the same side.
  • the central part comprises two fibers 26, for example metallic or aramid, and two beads 25.
  • the lips 23 are of substantially circular shape and between a bead 25 and a lip 23 remains a gutter 29 defining a free space receiving by snap-fastening the lip of an adjacent element. Indeed, the material of each element (polypropylene or nylon for example) is flexible enough to allow this snap.
  • Each lip 23 has at its center a fiber 27, for example metallic or aramid.
  • the elements do not include grooves and this without prejudice.
  • the elements of the same direction according to FIG. 1 may not have grooves, and the head-to-tail elements according to FIG. 2 may have grooves.
  • an umbilical cable 30 comprising an active core enveloped by an external sheath 40, a traction vault composed of two traction armors 41, 42, a hooping sheath 43.
  • the active core consists of a central rod 31, six coaxial cables 32 of a plastic envelope 33 coating the coaxial cables, several flexible pipes 34 ensuring the transport of fluids such as - for example, oxygen, helium, water, and finally a stuffing 35 ensuring the cylindrical external shape of the active core.
  • this active core can be any and include elements other than those described. If this core is sufficiently cylindrical, the inner sheath 40 is not essential, and in this case the vault bears directly on the active core.
  • This traction vault is formed of two armor wrapped in a long pitch helix and in opposite directions so that this vault is anti-rotating.
  • Each armor can of course be an armor such as those shown in Figures 1 and 2, or variants with or without grooves.
  • This vault is covered by a sheath 43 which holds the elements together.
  • the tensile armor as claimed can, of course, be laid on all types of cables, for example electric, optical fiber, fluid transport, or composite cables bringing together all or in part these characteristics.
