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.
- Such a coating layer can be extruded at the same time as the pultrusion of the rod and reduces the manufacturing steps.

- the cable comprises a first inner layer of conductive wires 2 of trapezoidal section and two outer layers of wires 3 of Z-shaped section wound in a reverse direction.
- Any combination of conductive wires of circular, trapezoidal and / or Z-shaped section may be used according to design considerations.
- the ring 1 is coated with a coating layer 6, which consists of carbon black and / or carbon nanotubes embedded in a resin, preferably epoxy or polyurethane, with a content sufficient to ensure electrical conduction between the rod 1 and the adjacent metallic conductor wires 2.
- a coating layer 6 which consists of carbon black and / or carbon nanotubes embedded in a resin, preferably epoxy or polyurethane, with a content sufficient to ensure electrical conduction between the rod 1 and the adjacent metallic conductor wires 2.
- the resistivity of the coating layer 6 is less than or equal to 10 +5 ⁇ .m and, advantageously, substantially equal to 10 +5 ⁇ .m.
- the coating layer comprises 4 to 8% by weight of carbon nanoparticles, and preferably substantially 4% by weight.
- the coating layer comprises 20 to 30% by weight of carbon black, and preferably substantially 20% by weight.
- a power transmission cable according to the invention comprises a central assembly 1 of composite unit rods 1A, 1B formed of fibers embedded in a resin, preferably carbon fibers pultruded in a resin epoxy, and around which are wound metal conductors son 2, 3, preferably aluminum or aluminum alloy.
- the set of unit rods 1 is coated with a first layer 4 and each unit ring 1A, 1B is covered with a second layer 5A, 5B.
- This set of unit rods 1 comprises a central unit ring 1A disposed on the longitudinal axis of the cable and around which are strung several other unitary rods 1 B, for example six in number.
- the central unitary ring 1A advantageously has a diameter of between 1 and 10 mm, preferably substantially equal to 4 mm, and the others Unit rods 1 B preferably have a diameter also between 1 and 10 mm, preferably substantially equal to 5.5 mm.
- the second layers 5A, 5B consist of carbon black and / or carbon nanotubes embedded in a resin, preferably epoxy, with a content sufficient to ensure electrical conduction between the rods and the first layer 4 is metallic preferably aluminum.
- the resistivity of the second coating layers 5A, 5B is less than or equal to 10 +5 ⁇ .m and advantageously substantially equal to 10 +5 ⁇ .m.
- the second coating layers comprise 4 to 8% by weight of carbon nanoparticles, and preferably substantially 4% by weight.
- the second coating layers comprise 20 to 30% by weight of carbon black, and preferably substantially 20% by weight.
