Definitions

  • the invention is in the field of electrical cables and wires and can be used in the design and manufacture of stranded conductors for flexible electrical lines.
  • the individual stranded elements are produced by saponifying or choking several fine individual wires.
  • the individual wires are firmly assigned to each other in layers. To do this, they run from supply spools that rotate about the stranding axis. - When strangling, the individual wires are not clearly assigned to each other. They run from fixed supplies and are gagged together (twisted) by a twisting device located behind the nipple.
  • a stranded wire as used in electrical cables and wires, can consist of a single stranded element (stranded or strangled) or - especially with a larger electrical conductor cross-section - of several stranded or strangled stranded elements (stranded or strangled), also called bundles.
  • Stranded strand elements so-called strand legs, contain a certain number of individual wires due to the layer structure.
  • Choked strand elements, so-called bundles can consist of any number of individual wires in the range between 10 and 100 wires. Constructions are also common in which a smaller number of individual wires form a choked sub-element and several choked sub-elements form the actual strand element, namely the bundle. (DE-OS 29 25 050).
  • the invention is based on the task of stranded conductors which have an electrically effective cross section of at least 16 mm 2 and consist of at least 80 fine wires to assemble and manufacture so that - compared to the known structures - with the same electrical cross-section results in a smaller spatial cross-section.
  • the bundles consist of at least two tresses, four to eight wires coming from a multiple wire drawing machine being combined to form one tress and several such tresses being fused into a bundle.
  • the wires can be better nested one inside the other, as a result of which the conductor becomes smaller in diameter.
  • a lower material consumption is achieved when applying the insulation for a given wall thickness.
  • smaller diameter smaller dimensions in the core and outer diameter also occur with multi-core cables. so that there is also less material here. consumption of inner and outer shells.
  • the stranding is associated with lower costs than the usual gagging.
  • An electrical conductor constructed in accordance with the invention can be considered for all movable electrical lines.
  • four to eight wires form a strand.
  • Two to about ten strands are then folded into a bundle, while the bundles are stranded in layers to the stranded conductor, for example in the staggering 1 + 6 + 12 + 18 etc. or 3 + 9 + 15 + 21 etc.
  • FIGS. 1 and 2 A stranded conductor designed according to the invention is shown in FIGS. 1 and 2, while the manufacture of the bundles forming the stranded conductor is shown schematically in FIGS. 3 and 4.
  • Fig. 1 shows a stranded conductor 1, which consists of seven bundles 2 stranded together in layers. 2, each bundle 2 consists of three strands 3, 4 and 5, which in turn are each composed of six individual wires 31, 41 and 51.
  • Fig. 3 shows three parallel multi-wire drawing machines 10, from each of which six individual wires 31 or 41 and 51 emerge and combined in the nipple 11 to form a strand 3 or 4 and 5 and then wound onto the winding drums 12, 13 and 14.
  • the strands 3, 4 and 5 run from the drums 12, 13 and 14 and are folded into a base bundle 2 in the nipple 15 and then wound onto the winding drum 16.
  • Several such bundles 2 are stranded in layers in a third operation to the stranded conductor.
