Definitions

  • the invention relates to an electrical line or an electrical cable at least one electrical conductor provided with electrical insulation, a screen formed by a wire mesh and a jacket.
  • electromagnetic compatibility the ability of an electrical device such as an electrical one Wire or an electrical cable, in its electromagnetic environment to function satisfactorily without this environment to which others too Institutions belong to influence impermissibly. If not enough Shielding electrical lines or cables there is a risk that electrical transmission media such as supply and communication networks or Control devices through the electromagnetic field surrounding them influence each other and there are disruptions. For example, at electrical devices and systems possible that the control by the Transmission of electrical power or electrical signals is disrupted.
  • EP 0 290 343 A1 describes an electrical cable in which the shield by two layers of copper braid and one between these two layers arranged band consisting of an iron-nickel alloy is formed. This structure of the screen leads to an improved shielding effect, he but also leads to a significant deterioration in flexibility and Fatigue strength of the cable.
  • the invention is the problem based on having a flexible electrical line or a flexible electrical cable an electromagnetic shield with a good shielding effect specify.
  • the advantages that can be achieved by the invention are, in particular, that very good shielding and therefore excellent electromagnetic Compatibility of the electrical line or the electrical cable can be achieved, since the electromagnetic radiation of the line or the cable is essential is reduced. It is advantageous for the best possible shielding effect if the particles of high relative permeability with large circumference are arranged. In this way, an undesirable impairment and Interference with neighboring other electrical devices is reliably avoided.
  • particles of high relative permeability in a through Wire mesh formed screen remains the flexibility and the flexural strength the line or cable. Because of their high flexibility and A line designed according to the invention is suitable for permanent bending strength particularly good for drag chain cables. The line or cable is also easy and inexpensive to manufacture.
  • the relative permeability of the particles is at least 1000.
  • Such materials are So-called ferromagnetic materials, as they also under the trade name Permalloy or the designation ⁇ -metals are known.
  • the particles have a high relative permeability made of an iron-nickel alloy are trained.
  • Such alloys are e.g. B. under the Trade names Permalloy available inexpensively.
  • the particles have a high relative permeability Fleece are embedded and this fleece is arranged in the screen.
  • particles of high relative permeability e.g. B. one Iron-nickel powder, from the actual manufacture of the cable or line separate, so that the latter is simplified.
  • the wire mesh is formed from copper wires.
  • the flexible electrical low-voltage line shown by way of example in FIG. 1, those for the transmission of electrical signals or electrical power is usable, e.g. B.
  • three electrical conductors 1, each with an electrical Insulation 2 are provided.
  • the isolated electrical conductors 1 are in the Embodiment shown together by an inner jacket 3rd enclosed, on which a plastic film 4 is applied. About it is a enclosed, on which a plastic film 4 is applied. About it is a Wire mesh 5 is provided, which forms an electromagnetic screen 6.
  • an outer jacket 8 is applied directly to the screen 6.
  • the relative permeability of the particles used which is also referred to as the permeability number and is abbreviated to ⁇ r , is advantageously at least 1000 in order to ensure a high shielding effect of the screen 6 and the electromagnetic compatibility of the electrical line or the electrical cable.
  • Particularly suitable materials for the particles 7 of high relative permeability are iron-nickel alloys, which are also known as ⁇ -metals or are known under the trade name Permalloy alloys, and have a high relative permeability number of up to 10 5 to 10 6 and comparatively are available inexpensively.
  • the second shows an example of a medium-voltage cable, one with a electrical insulation 2 provided electrical conductor 1. Between the electrical conductor 1 and electrical insulation 2 are an inner conductive layer 11 and an outer conductive layer 12 immediately above the electrical insulation 2 educated.
  • an electromagnetic screen 6 is provided, which at this embodiment of a fleece 13, in the particles 7 high relative Permeability are embedded, and a copper tape 14 wound over it is formed.
  • the fleece 13 contains high relative permeability e.g. B. copper threads or soot particles 16 to ensure sufficient electrical Ensure the conductivity of the fleece 13. This is especially the case with higher ones Nominal voltages are an advantage.
  • the fleece 13 it is also possible to use the fleece 13 to be arranged above the wound copper strip 14.
  • Metal tape having electrical conductivity can be used for the screen 6 of course, just such metal wires or a combination of metal wires and metal bands are used, the fleece in any position in the screen can be arranged.
  • the screen 6 is e.g. B. from a wrap 15 of tapes and / or films enclosed, over which the jacket 8 is formed.
