Definitions

  • the picture 2 shows another coaxial power cable 20 comprising several internal conductors, three conductors 22, 24 and 26 in the example shown.
  • the three conductors 22, 24 and 26 extend along the axis 16 and parallel thereto.
  • the three conductors 22, 24 and 26 are surrounded by the conductor 12 similar to that of the figure 1 .
  • the cable 20 is well suited to transporting a three-phase current. Each phase is carried by one of the conductors 22, 24 and 26.
  • the conductor 12 can carry a neutral of the electrical system.
  • the invention can be implemented regardless of the number of phases.
  • One internal conductor is provided per phase. All inner conductors are surrounded by outer conductor 12.
  • the insert includes a ferromagnetic material. This type of material makes it possible to generate an inductive part in the specific impedance of the insert.
  • the insert is configured not to create a loop around the internal conductor(s). The absence of a loop around the internal conductor(s) prevents the ferromagnetic material of the insert from saturating when large currents pass through the internal conductor(s).
  • each of the cables 10 and 20 comprises only one insert.
  • each of the cables 10 and 20 can comprise several inserts and more precisely as many as necessary to produce an adequate filter.
  • the insert may comprise an electrically conductive material providing electrical insulation with respect to at least one of the conductors.
  • a conductive material makes it possible to reduce the distance separating the external conductor from the internal conductor(s), which makes it possible to increase the value of the capacitance separating the internal conductor(s) from the external conductor.
  • the insert may comprise, in addition to the ferromagnetic material, a diamagnetic or paramagnetic material. By increasing the magnetic permeability, the insert can increase the inductance value between the inner conductor(s) and the outer conductor.
  • the cable 60 comprises, at one of its ends, a plug 66 partially covering the outer conductor 12.
  • the inner conductor 14 extends beyond the end of the outer conductor 12 and passes through the plug 66.
  • the connection of end 62 makes it possible to connect to each of the conductors 12 and 14 an electrical conductor, respectively 72 and 74.
  • the conductor 74 has at its end a terminal 76 held on the axial end of the inner conductor 14 by means of a screw 78. Any other means of electrical connection of the conductor 74 to the inner conductor 14 is possible, for example, by means of a collar encircling the inner conductor 14 and providing radial contact around the end of the inner conductor 14.
