Definitions

  • the present invention relates to a longitudinal and cross waterproof electrical power cable with one over a conductor insulation or one above located conductive layer arranged screen metallic wires or ribbons and one as Cross water barrier serving closed metallic Shell in the further layer structure, whereby between the Screen and the metallic shell at least one Moisturizing materials containing tape is provided.
  • the invention has for its object a Possibility to find that allows the screen area an electrical power cable against Seal moisture transmission, as well as additionally to ensure that potential differences in potential between the electrical shield of the power cable and which ensures the cross-water tightness of the cable avoid metallic shells from the start.
  • swellable material band also contains conductive inserts made of metal.
  • the swellable Material ensures local penetration Moisture, e.g. B. after mechanical damage to the Outer shell and the metallic shell. That at Water swelling material closes at the Damage existing cavities and thus prevents further moisture penetration into the Cable interior.
  • Cross helix immediately encloses and above this band the metallic shell, e.g. B. in the form of a overlapping band edges of applied aluminum band, is arranged.
  • the tape used is a swellable material containing and doped with metal particles is.
  • a swellable material containing and doped with metal particles is.
  • source fleeces Layered plastic nonwovens, the layers of which swellable material are constructed or such contain. Swellable masses, for example in powder form, can but those based on cellulose are also those based synthetic materials.
  • Such tapes allow one short-term moisture access to the swellable Material.
  • simple manufacturing process guaranteed and ensures that the cable seal provided materials even after the manufacture of the Cable, transport or its relocation to the Locations are available where there is moisture intrusion effectively block the damage site.
  • the next to the swellable material in the Swellable fleece contained conductive inserts made of metal can, for example, by metal spangles or short Threads, for example made of copper or aluminum be.
  • the usual wall thickness of such swellable nonwovens sure that over the cable length a permanent metallic conductive contact between the metallic shield of the Cable and that used for water resistance metallic shell is ensured.
  • the tape is a swellable Material containing and with metallic threads or Stripe is woven fleece tape.
  • the metallic one Thread or the strip e.g. B. made of aluminum or copper manufactured, runs alternately from one surface of the tape to the other, in addition to the simultaneous, easy contacting of the metallic shield and the metallic shell secures them
  • Embodiment regular cross connections along the entire cable route As with the first Possible potential differences are still embodiment balanced along the cable, special measures to Compensation of potential differences, for example in the socket area, are no longer required.
  • Layer structure of the cable can be such that the swellable material and conductive inserts containing tape runs in the longitudinal direction of the cable. Instead of Of a single volume, it can often be useful to at Cable opposite sides two or more tapes in Let it run longitudinally. This is particularly so then the case if in the manufacturing process on additional Winding devices should be dispensed with.
  • the invention is based on the in the figure as Embodiment shown electrical means or High-voltage cable explained in more detail.
  • Single wire existing conductor 1 of this cable is the So-called inner conductive layer 2, for example from one soot-filled polymer material, extruded.
  • inner conductive layer 2 closes the electrical Insulation 3, for example from a networked Polyethylene, it is covered by the so-called outer conductive layer 4, shown in Embodiment also from a soot-filled conductive polymeric material such as polyethylene or one of his copolymers.
  • a conductive tape 5 over the outer conductive layer 4 arranged, for example by graphite or carbon black made crepe paper tape, optionally in Combination with a swellable nonwoven tape.
  • This conductive Volume 5 serves practically as a cushion layer for the one above located screen 6 from z.
  • copper wires made by a so-called transverse spiral also made of copper are wrapped.
  • moisture band 7 for plugging the screen area and to prevent forwarding at one point in the Cable is used for moisture band 7 according to the invention, also swelling fleece, the by means of, for example, copper or aluminum existing deposits, such as tinsel or threads, are more limited Length or knitted threads or strips, one constant contact between the screen 6 and the over the metallic sheath 8 arranged in the band 7 guaranteed.
  • This metallic shell 8 is for example one on the polyethylene outer jacket 9 facing surface with a copolymer of ethylene or a hot melt coated aluminum tape, whose band edges overlap each other and which in Overlap area are glued together.
  • a copolymer of ethylene or a hot melt coated aluminum tape whose band edges overlap each other and which in Overlap area are glued together.
