Definitions

  • the present invention relates to a cable intended for transmitting both electrical power and video and / or remote control signals.
  • This cable is more particularly intended to supply electrical energy and the remote control of an underwater vehicle to a system as described in the patent application filed on the same day as this application by the same owner and entitled : "Improvements to filo-guided underwater vehicles.”
  • the present invention proposes to provide a cable meeting the requirements specified above.
  • the invention relates to a conductive cable with a high filling rate and having a small variation in volume as a function of the hydrostatic external pressure intended for the transmission of electrical energy and of video and / or remote control signals, characterized in that that it has a coaxial structure and in that it comprises a core ensuring the transmission of video and / or remote control signals and at least two coaxial conductive layers each consisting of a plurality of small diameter electrical conductors coated in the form of '' a covering and isolated from each other by an insulating sheath, preferably made of polytetrafluoroethylene (Teflon), the tensile strength being obtained by a sheath made of synthetic or natural fibers.
  • Teflon polytetrafluoroethylene
  • the transmission of the video and / or remote control signals can be carried out either using a mini coaxial cable or via one or more optical fibers of the multimode, single mode or other type.
  • the cable can also be provided with an outer buoyancy sheath 28 ensuring slightly negative buoyancy.
  • a cable according to the invention having a diameter on an outer sheath 26 of the order of 5 mm makes it possible to transfer electrical energy of 20 Kw at a voltage of 4000 volts with a yield equal to or greater than 0.7 under the conditions of use mentioned above, that is to say in deep immersion, of the order of 300 m, and under a length of 1000 to 1300 m, with a excellent tensile strength, of the order of 500 daN, and a small variation in volume as a function of the hydrostatic external pressure.
  • This cable also has the advantage of being non-magnetic.
