Definitions

  • the present invention relates to a cable jacket, in particular a rubber jacket for a welding cable and adapted to enclose groups of electrical conductors and coolant ducts for conducting a pressurized medium for cooling the cable, comprising a first, inner rubber layer, at least one reinforcement layer of warp-knit type radially outwardly of the first layer, at least one reinforcement cord helically wound radially outside the reinforcement layer, and an outer rubber layer radially outwardly of the cord.
  • the primary purpose of the present invention is therefore to achieve a cable jacket which, even with very short lengths, is sufficiently flexible with regard to both bending and torsion, and is capable of absorbing the circumferential tensile forces in the jacket arising due to the pressure exerted by the coolant in the cable and the repelling radial forces generated by the cable cores every time the current through the cable is turned on or off.
  • the cable jacket described by way of introduction is characterized, according to the invention, in that the reinforcement layers of warp-knit type and of the cord are mutually radially spaced by an intermediate rubber layer, and in that the reinforcement cord consists of a twined multifilament string, the spacing between adjacent cord windings measuring in the longitudinal direction of the jacket about 2-8 mm, preferably 4 mm.
  • the cable jacket comprises two or more cords
  • the cords are unidirectionally wound in a common circumferential plane in order to prevent the jacket with the warp-knit reinforcement from expanding too much due to inner pressure and to provide good torsional properties at the same time.
  • the jacket 2 comprises two reinforcement layers 9 of a warp-knit fabric which is known per se and a cord helix 10 lying outside said two layers.
  • Warp-knit fabric refers in this context to a textile construction in which yarns, usually filament yarns, are interlooped by knitting, with the yarn threads running essentially in the longitudinal direction of the fabric.
  • Fig. 2 shows more clearly the structure of a jacket according to the invention, which only shows one layer of warp-knit reinforcement 9, starting from the inside, the jacket 2 has a rubber layer 11, a warp-knit reinforcement 9, a thin layer 12 of rubber, a helically wound layer 10 e.g. of lightly twined polyester, and an outer layer 13 of rubber.
  • cords 10 In order to obtain the desired flexibility both for bending and torsion, as well as form strength, since the jacket is subjected to higher inner pressure by the coolant and radial repellant forces generated by the cable cores whenever the current through the cable is turned on or off, it is essential that if a plurality of cords 10 are used that they run parallel to each other and be wound in the same direction, i.e. not crossing each other.
  • the cords should be wound leaving a gap to about 2-8 mm, preferably about 4 mm, between adjacent cord windings.
  • a cable jacket according to the invention is made preferably in finite lengths by being built up on a mandrel, with one or two layers of warp-knit fabric being applied around the inner rubber layer 11. If there is more than one layer, a thin layer of rubber should be placed between the layers, and a thin layer 12 outside the outer warp knit layer 9.
  • a single cord 10 of previously described type is then wound around the layer 12 helically with a pitch so that the distance between the adjacent windings of the cord will be about 2-8 mm, preferably about 4 mm, at a normal jacket diameter of about 5-6 cm.
