Definitions

  • Electrical cables carrying signals in the form of low current currents are particularly sensitive to electromagnetic interference to which these cables may be subjected. This is particularly the case of cables used in the telecommunications field. These cables carry analog or digital signals. They consist mainly of a central core composed of numerous electrical conductors insulated from each other and a screen formed by a metal envelope surrounding the central core. The protection against interference of the signals transported by the conducting wires with the electromagnetic waves surrounding the cable is provided by the screen. The electromagnetic performance of the cable depends in particular on the efficiency of the screen. The latter must therefore be free from defects and in particular must not be pierced or have electrical discontinuities that would make it sensitive to electromagnetic disturbances.
  • the screen is in the form of a ribbon formed of a composite sheet wound around all the conductors.
  • the composite sheet comprises layers of different materials, including a layer of polyethylene terepthalate or polyester (PET) and a metal layer (copper or tin).
  • PET polyethylene terepthalate or polyester
  • metal layer copper or tin
  • the present invention relates to an electric cable provided with a high performance screen, satisfying electromagnetic compatibility tests without using an additional metal sheath.
  • the manufacturing cost is therefore reduced compared to the cables of the prior art.
  • Curve 44 of FIG. 5 corresponds to a screen according to the invention, with the same structure as for FIG. 4 (a PET substrate 12 microns thick sandwiched between two layers of Al 25 micrometers thick. thickness), but the ribbon is welded longitudinally to the ultrasound so as to ensure electrical continuity between the longitudinal edges of the ribbon. Note that the values of ZT are lower than the values defined by the curve 40, which demonstrates the good efficiency of the screen against disturbing electromagnetic waves. One can thus do without an additional metallic sheath surrounding the screen.
