Definitions

  • the invention relates to a cable for the transmission of electricity, in particular air, comprising a set of composite rods.
  • Overhead cables with composite central rods forming a mechanical support of conductive wires wound around rods made of fibers pultruded in a resin are known.
  • the unitary rods are formed of carbon fibers pultruded in a resin, for example an epoxy resin, and are covered with a metal sheet intended to form a protective buffer layer of the rod, in order to increase its resistance to curvature and shock, and also prevent deterioration of the resin caused by heat.
  • the metal foil may be aluminum.
  • Another advantage of such an aluminum cover sheet may be to provide electrical conduction avoiding significant differences in potential between the pultruded composite rod or the composite pultruded rods and the surrounding conductors son (s).
  • a ring having an inner portion and an outer portion.
  • the inner portion is formed of fibers in a resin and the outer portion is also formed of fibers in a resin in which thermally conductive particles, for example aluminum, are added, for example with a content of 20 to 50% by weight. , or carbon black and / or carbon nanotubes, for example at a rate of less than 3%.
  • the object of the invention is to provide electrical conduction avoiding large potential differences between the pultruded composite rod or the pultruded composite rods and the conductive wires that surround it, by means of a more economical material than aluminum and easy to manufacture.
  • the invention proposes a power transmission cable comprising at least one composite central rod formed of fibers embedded in a resin and around which are arranged metal conductor wires, said rod being coated with a layer coating material consisting of carbon black embedded in a resin, characterized in that said coating layer consists of only 20 to 30% by weight of carbon black embedded in said resin.
