Description

CABLE DE TRANSPORT D'ELECTRI Cl TE A JONCS COMPOSI TES  ELECTRIC TRANSPORT CABLE Cl TE A JONCS COMPOSI TES
L'invention concerne un câble de transport d'électricité en particulier aérien comportant un ensemble de joncs composites. The invention relates to a cable for the transmission of electricity, in particular air, comprising a set of composite rods.
Des câbles aériens à joncs centraux composites, formant un support mécanique de fils conducteurs enroulés autour de joncs constitués de fibres pultrudées dans une résine sont connus.  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.
Selon le document de brevet JP 3-129606, les joncs unitaires sont formés de fibres de carbone pultrudées dans une résine, par exemple une résine époxy, et sont recouverts d'une feuille métallique destinée à former une couche tampon de protection du jonc, afin d'augmenter sa résistance à la courbure et aux chocs, et également éviter une détérioration de la résine provoquée par la chaleur. La feuille métallique peut être en aluminium.  According to the patent document JP 3-129606, the unit 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, so as to to increase its resistance to curvature and shocks, and also to avoid deterioration of the resin caused by heat. The metal foil may be aluminum.
Un autre avantage d'une telle feuille de recouvrement en aluminium peut être d'assurer une conduction électrique évitant de fortes différences de potentiel entre le jonc composite pultrudé ou les joncs composites pultrudés et les fils conducteurs qui le(s) entourent.  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).
Cependant, cette solution est coûteuse, compte-tenu du prix de l'aluminium et de l'étape supplémentaire de fabrication que cela engendre.  However, this solution is expensive, given the price of aluminum and the additional manufacturing step that entails.
En effet, une telle feuille en aluminium est enroulée autour du jonc et ses bords sont soudés longitudinalement. Il en résulte une opération de fabrication séparée de la pultrusion du jonc.  Indeed, such an aluminum sheet is wrapped around the ring and its edges are welded longitudinally. This results in a separate manufacturing operation of the pultrusion of the rod.
Par ailleurs, il est connu du document de brevet US 2012/0186851 un jonc comportant une portion interne et une portion externe. La portion interne est formée de fibres dans une résine et la portion externe est également formée de fibres dans une résine dans laquelle on ajoute des particules conductrices thermiques, par exemple de l'aluminium, par exemple avec un taux de 20 à 50% en poids, ou du noir de carbone et/ou en nanotubes de carbone, par exemple à un taux inférieur à 3%.  Furthermore, it is known from the patent document US 2012/0186851 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%.
Or avec une telle teneur, si les charges peuvent impacter sur la résistance mécanique, elles n'ont pas d'effet électrique car cette teneur n'entraîne pas de percolation électrique et n'assure pas de conduction électrique entre le jonc composite pultrudé ou les joncs composites pultrudés et les fils conducteurs qui le(s) entourent. But with such a content, if the charges can impact the mechanical strength, they have no electrical effect because this content does not cause electrical percolation and does not conduct conduction between the pultruded composite rod or the pultruded composite rods and the conductive wires surrounding it.
L'objet de l'invention est d'assurer une conduction électrique évitant de fortes différences de potentiel entre le jonc composite pultrudé ou les joncs composites pultrudés et les fils conducteurs qui le(s) entourent, au moyen d'un matériau plus économique que l'aluminium et de fabrication aisée.  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.
Pour ce faire, l'invention propose un câble de transport d'électricité comportant au moins un jonc central composite formés de fibres noyées dans une résine et autour duquel sont disposés des fils conducteurs métalliques, ledit jonc étant revêtu d'une couche de revêtement constituée de noir de carbone et/ou de nanotubes de carbone noyés dans une résine, caractérisé en ce que la teneur en noir de carbone et/ou en nanotubes de carbone est telle que la résistivité de ladite couche de revêtement est inférieure ou égale à 10+5 Ω.ΓΤΙ . To do this, 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 coating layer constituted of carbon black and / or carbon nanotubes embedded in a resin, characterized in that the content of carbon black and / or carbon nanotubes is such that the resistivity of said coating layer is less than or equal to 10 + 5 Ω.ΓΤΙ.
Une telle couche de revêtement peut être extrudée en même temps que la pultrusion du jonc et réduit les étapes de fabrication.  Such a coating layer can be extruded at the same time as the pultrusion of the rod and reduces the manufacturing steps.
De préférence, la résistivité de ladite couche de revêtement est sensiblement égale à 10+5 Ω.ΓΠ. Preferably, the resistivity of said coating layer is substantially equal to 10 +5 Ω.ΓΠ.
Avantageusement, ladite couche de revêtement est constituée uniquement de noir de carbone et/ou de nanotubes de carbone noyés dans une résine  Advantageously, said coating layer consists solely of carbon black and / or carbon nanotubes embedded in a resin
Selon un premier mode de réalisation, ladite couche de revêtement comporte 4 à 8% en poids de nanoparticules de carbone.  According to a first embodiment, said coating layer comprises 4 to 8% by weight of carbon nanoparticles.
De préférence, ladite couche de revêtement comporte 4% en poids de nanoparticules de carbone.  Preferably, said coating layer comprises 4% by weight of carbon nanoparticles.
Selon un second mode de réalisation, ladite couche de revêtement comporte 20 à 30% en poids de noir de carbone.  According to a second embodiment, said coating layer comprises 20 to 30% by weight of carbon black.
