Definitions

  • the invention is in the field of electrical cables and wires and can be used in the structural design of a stranded conductor for flexible electrical lines.
  • Stranded conductors for electrical cables and wires consist of one or more stranded elements (bundles), which are made by stranding or twisting several fine individual wires.
  • stranded strand elements the individual wires are firmly assigned to one another in layers. As a result of the layer structure, these strand elements contain a very specific number of individual wires. In the case of strangled strand elements, the individual wires are not clearly assigned to one another.
  • These stranded elements 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-A-29 25 050).
  • the invention is based on the object of constructing a stranded conductor which has an electrically effective cross section of at least 4 mm 2 in such a way that - compared to the known structures - the same is electrical effective cross section results in a smaller spatial cross section.
  • additional strand elements are arranged in the gusset spaces of the stranded bundles.
  • the electrically effective cross section of the stranded bundles and thus also the spatial cross section of these bundles can be chosen to be smaller. This results in a reduced diameter of the stranded conductor as a whole. This results in lower material consumption when applying the insulation for a given wall thickness. As a result of the smaller diameter of the stranded conductor and thus also the wire, smaller dimensions in the core and outer diameter occur in the case of multi-core cables, so that less material is used for the inner and outer sheath.
  • the stranded elements arranged in the gusset spaces can be stranded or choked elements. However, strands are preferably also considered, in which several fine wires are combined into a stranded element without being twisted or unwrapped. Fine wires are used for the strand elements arranged in the gusset spaces, the diameter of which is smaller or at most equal to the diameter of the wires used for the bundles.
  • the diameter reduction of the new stranded conductor is particularly important when three or four bundles form a stranded conductor, since this results in relatively large gusset spaces.
