Definitions

  • the invention relates to an electrical cable, preferably for an operating voltage greater than 1000 volts, with at least three single-core cables, which are each provided with at least one conductor, one or more surrounding insulating layers and an outer sheath.
  • the cable should be kept compact in relation to the outer diameter and be formed approximately like a standard cable. Furthermore, the cable should also be bendable and can be mounted in the bent state.
  • This novel cable results in completely new applications in vertical installations, in particular in vertically extending pressure pipes in pumped storage power plants, in ventilation shafts, in buildings or the like.
  • at least one cable can be suspended, for example, in a vertically extending vent shaft with a length of up to several hundred meters without any attachment, wherein the cable is guided horizontally and then passed vertically into the vent shaft and again can be led away horizontally.
  • Fig. 1 shows an electrical cable 20 for a three-phase operation for medium voltage and high voltage cables, which are preferably used for operating voltages greater than 1000 V, which preferably comprises three single-core cable 10.
  • the support elements 22 parallel to the juxtaposed launch cables 10, there are additionally three support elements 22 which are each formed from a steel cable 25 and an insulation 24 surrounding it. Outside these three advantageously interacting single-conductor cable 10, the three, each arranged between two single-core cables 10, to the single-core cable 10 pressed support elements 22 are positioned.
  • the single conductor cable 10 and the support members 22 are stranded together and held together by a bandage 26 over the entire cable called stranding cable.
  • This bandage 26 is provided, for example, as around the lead-in cable 10 and the support members 22 around helically wound tape which presses the support members to the single-core cable and thus sufficient static friction between them is ensured in the assembled state of the cable 20.
  • the cable 20 is also surrounded by a single or multi-layered protective jacket 23, which protects the cable, especially when mounting against mechanical damage.
  • the respective single-core cables 10 are composed of a conductor 12 and a multi-layered insulation.
  • a semiconductor layer 13, a surrounding dielectric isolation layer 14, a further semiconductor layer 15, a semiconductor source strip 18 or an outer shell 11 are applied to the conductor 12 by standard materials and production methods in order to ensure secured aging values of the cable.
  • the conductor 12 is preferably made of a copper or aluminum cable of a plurality of wires or strands 12 '.
  • Fig. 1 The stranding according to Fig. 1 can be supplemented by further, such as by a so-called Singeltube, which is intended for the subsequent blowing of fiber optic cables, or by appropriate control and / or power cable.
  • Singeltube which is intended for the subsequent blowing of fiber optic cables, or by appropriate control and / or power cable.
