Definitions

  • the invention relates to an electrical power line with a central support element, several around the central one Support element stranded, one electrical conductor each and an overlying insulation Energy veins and an outer jacket.
  • Such electrical power lines are for example as a so-called flexible and reelable Power supply lines more portable Consumers such as B. for the energy supply of elevators used on construction sites.
  • the electrical ones Power lines with high mechanical stress exposed. While winding or unwinding one reelable high-voltage power lines have a considerable and tensile forces on the line.
  • a steel cable as the central supporting element. How is described in DE 33 35 325 A1, such central steel cable with a Be rubber coated.
  • the use of a Steel rope as the central supporting element has the Disadvantage that the flexibility of the power line is reduced.
  • not in all cases ensures good mechanical contact between the central support element and the energy veins exists and the central support element in sufficient Dimensions for mechanical relief of the energy veins and the entire power line is used.
  • the invention is therefore based on the problem of a central supporting element having electrical Power line to train such that they have a high Has flexibility and even with high mechanical Reliable protection against stress is.
  • the central support element one at least essentially made of plastic existing core and applied to this core train high tensile threads and each of the energy veins to be braided.
  • the core of the support element is made of an ethylene-propylene elastomer such as B. EPDM (ethylene / propylene-diene terpolymer) is trained.
  • B. EPDM ethylene / propylene-diene terpolymer
  • control line and communication line one Have braiding.
  • the flexible example shown in the figure electrical power line 1 has a central Support element 3 on a z. B. from an ethylene-propylene elastomer like EPDM (ethylene / propylene-diene terpolymer) existing core 5 and this core 5 applied high tensile threads 7.
  • Both high tensile threads 7 are, for example high resistance to stretching and great strength and pliable aramid fibers as shown below are sold under the trade name "Kevlar".
  • Threads 7 in the form of spinning onto the core 5 upset.
  • Around the central support element 3 are several for example, four energy wires 9 stranded.
  • any of these Energy wires 9 has an electrical conductor 11 and one overlying electrical insulation 13 and a outer braiding 15, for example as an open Braid is formed from rayon threads. Between the Insulation 13 and the braiding 15 of each energy core 9 is, for example, a thin film 16 z. B. made of polyester, which is a possible puncture prevented by braid elements. Through the Braiding 15 of the energy veins 9 and around the core 5 applied high tensile threads 7 becomes an intimate Contact and high liability between the central Support element 3 and the energy wires 9 stranded around it especially in the case of mechanical stress on the Power line 1 guaranteed.
  • Control lines 19 and / or communication lines 21 be arranged.
  • the one shown in the figure Embodiment are in three outer gussets 17 each a control line 19 and in an outer gusset 17 one Message line 21 arranged.
  • Each of the Control lines 19 have two stranded to the pair Control cores 23 on a thin film 28 z. B. made of polyester and above, for example as a open braid trained braid 24 from z. B. Rayon threads are surrounded.
  • the message line 21 has for example two twisted together Communication lines 25 and is also thin Foil 29 made of polyester and one of them as an open one Braid formed braid 26 from rayon threads enclosed.
  • Braids 24 and 26 ensure that the control lines 19 and the message line 21st with in the from the energy veins 9 and the central Support element 3 trained tensile composite are included.
  • the films 28 and 29 form the Pad for braids 24 and 26 and prevent a possible puncture of braid elements.
  • the support element 3, energy wires 9, control lines 19th and communication line 21 is existing stranding enclosed by a gusset-filling inner jacket 31.
  • An outer jacket 33 is provided in the one open braid 35 z. B. is integrated from rayon threads.
