Definitions

  • the present invention is a multi-core flexible electrical line according to the preamble of claim 1.
  • Flexible cables find their application z. B. as electrical supply lines for moving machinery, the cables can be drummed or towed.
  • Application sites are opencast mining and underground mining.
  • FIG. 1 shows a section through a line according to the teachings of the invention.
  • the line has three main wires 1, which consist of a highly flexible, fine-stranded copper conductor 1 a and an insulating layer 1 b based on EPR. Between the main wires 1 there are protective conductors 2, which, like the main wires 1, have a highly flexible, finely stranded copper conductor 2a and an insulation 2b based on EPR.
  • a support member 3 is provided, which has a torsion-free steel cable 3a and an insulating rubber sheath 3b.
  • the jacket 5 consists of two layers 5a and 5b, between which a Torsionstikgeflecht 4 is provided.
  • the layers 5a and 5b are advantageously made of a chlorine-containing rubber which is oil-resistant, flame-retardant and tear-resistant and resistant to abrasion.
  • the torsion protection braid is constructed of high tensile and abrasion resistant plastic threads.
  • the support member 3 can be advantageously used as a control conductor or as an overload.
  • the main wires 1 and the protective conductor 2 are roped on the support member 3.
  • FIG. 2 shows the steel cable 3a on an enlarged scale.
  • the steel cable 3a consists of a core strand 6 of, for example, seven individual wires.
  • the core strand is surrounded by four strands 7, which are each composed of twenty-six individual wires.
  • An outer layer is formed of sixteen outer strands, which, like the Kernlitze 6 consist of seven individual wires.
  • the strands 7 of the first layer are stranded with a lay length of 35 mm on the core strand 6.
  • the outer strands 10 of the second layer are roped to the first layer with a lay length of 50 mm.
  • the bearing element constructed in this way gives the cable an extremely high bending fatigue strength and thus a very long service life.

Ligne électrique multiconducteurs flexible, avec un élément support central (3), plusieurs conducteurs (1) entourant l'élément support (3) en conducteurs isolés à fil de faible diamètre, et avec une gaine en matière plastique (5) dans laquelle l'élément support (3) est en un câble métallique antigiratoire (3a), muni d'une couche isolante extérieure (3b), caractérisé en ce que le câble métallique (3a) consiste en un toron central (6), en une couche de plusieurs torons (7) câblée sur le premier toron central (6) et en une deuxième couche d'une pluralité de torons (10) qui est câblée sur la première couche, le sens de câblage et/ou la longueur de câblage des torons (10) de la deuxième couche étant différent du sens de câblage et/ou de la longueur de câblage des torons (7) de la première couche.
  2. Ligne multiconducteurs selon la revendication 1, caractérisée en ce que dans les coins de câblage de la première couche sont disposés des torons supplémentaires (8) dont le diamètre est inférieur au diamètre des torons (7) de la première couche et en ce que les torons (7) de la première couche et les torons supplémentaires (8) admettent une enveloppante commune par l'intérieur.
  3. Ligne multiconducteurs selon la revendication 1 ou 2, caractérisée en ce que des conducteurs de protection (2) sont disposés entre les conducteurs (1).
  4. Ligne multiconducteurs selon l'une quelconque des revendications 1 à 3, caractérisée en ce que l'isolation des conducteurs (1) est en caoutchouc éthylène-propylène (EPR).
  5. Ligne multiconducteurs selon l'une quelconque des revendications 1 à 4, caractérisée en ce que la gaine extérieure (5) consiste en deux couches (5a, 5b) en un caoutchouc, et en ce que entre les deux couches (5a, 5b) est incorporé un tressage antitorsion (4) en fils de matière plastique à haute résistance à la traction.
