Definitions

  • the invention relates to a cable with a tensile cable sheath according to the preamble of the main claim.
  • a cable is known from DE-OS 34 14 638. It contains a tensile mesh tape with aramid longitudinal threads and cross threads made of another plastic, onto which a plastic outer jacket is extruded. When the plastic outer jacket shrinks, the tensile band becomes wavy, so that subsequently occurring tensile forces are not absorbed by the tensile band until it is stretched again.
  • the invention has for its object to provide a cable with a shrink resistant, tensile cable sheath.
  • the new cable is easy and inexpensive to manufacture.
  • the compression stability is increased without significantly impairing their flexibility.
  • the combination of tensile and compressive elements in a band can in particular air cables with high tensile strength and small diameter, ie. H. be manufactured to save weight, which results in a large possible span length.
  • a cable core 1 contains a cable core 1 with a structure known to the person skilled in the art.
  • a mesh tape which consists of parallel longitudinal threads 3, 4 and transverse threads 5.
  • Part 3 of the longitudinal threads consists of tensile aramid or glass threads, the other part 4 of tensile and compressive threads made of aramid or glass fiber reinforced plastic (for example LLS-045 from Neptco, USA) or a liquid crystal polymer (for example Vektra B900 from Celanese) or an aramid or glass fiber reinforced liquid crystal polymer.
  • the Cross threads 5 are made of a different plastic.
  • a plastic outer jacket 6 is extruded onto the grid tape, which melts the threads of the grid tape when it is applied or fuses with the transverse threads 5 if their material is identical to that of the plastic outer jacket 6.
  • the cable core 1 consists of a hollow wire (in another embodiment, a loose tube), around which a tape is placed lengthwise butt-to-butt, which is constructed like the grid tape, but in contrast to this there are no gaps between has the longitudinal threads.
  • a plastic outer jacket 6 is applied over it.
  • the tape is placed around the cable core 1 at a small angle to the longitudinal axis of the cable.
  • the joint of the tape runs helically. After the helix has made about half a turn, its direction reverses.
  • Such a cable has a better flexibility than that described above without the tensile strength and compressive strength deteriorating appreciably.
