Description

L'invention concerne un câble de transport d'énergie électrique en particulier basse tension.The invention relates to a cable for transporting electrical energy, particularly low voltage.

Elle concerne plus précisément un câble de transport d'énergie électrique comportant un noyau central de fils d'aluminium recouverts d'un revêtement métallique et une couche périphérique constituée au moins partiellement de fils de cuivre.More specifically, it relates to an electric power transmission cable comprising a central core of aluminum wires coated with a metal coating and a peripheral layer at least partially made of copper wires.

Le document de brevet EP 2 224 257 décrit un tel câble dont les fils d'aluminium du noyau central sont revêtus d'une couche de cuivre.The patent document EP 2,224,257 describes such a cable whose aluminum son of the central core are coated with a copper layer.

Si un tel agencement évite la formation d'alumine sur les fils en aluminium en présence d'oxygène et permet d'assurer une bonne conductivité à la connexion d'une cosse tout en permettant l'obtention d'un câble plus léger, le problème technique que pose une telle solution est la corrosion galvanique entre le cuivre et l'aluminium à l'extrémité d'un tel câble ou lors des perforations du revêtement en cuivre des fils d'aluminium. Il en résulte une corrosion galvanique créant une variation de la résistance électrique de contact entre des connexions ou des cosses d'extrém ité et de tels câbles relativement im portante.If such an arrangement avoids the formation of alumina on the aluminum son in the presence of oxygen and ensures good conductivity to the connection of a pod while allowing to obtain a lighter cable, the problem Such a solution poses the technical problem of galvanic corrosion between copper and aluminum at the end of such a cable or during perforations of the copper coating of the aluminum wires. This results in galvanic corrosion creating a variation in the electrical contact resistance between end connections or lugs and such relatively large cables.

Le document de brevet US 3 683 103 décrit un câble de transport d'énergie électrique comportant un noyau central de fils d'aluminium et une couche périphérique constituée au moins partiellement de fils de cuivre, ces fils d'aluminium et de cuivre étant recouverts d'une couche de revêtement en métal ou alliage métallique afin d'éliminer la corrosion galvanique. Cette couche de revêtement en métal peut être en argent, en nickel ou en étain et présente une épaisseur minimale de 1 micron.The patent document US 3,683,103 discloses an electric power transmission cable having a central core of aluminum wires and a peripheral layer at least partially made of copper wires, these aluminum and copper wires being coated with a layer of metal coating or metal alloy to eliminate galvanic corrosion. This metal coating layer may be silver, nickel or tin and has a minimum thickness of 1 micron.

Lors du sertissage d'une cosse d'extrémité ou d'une connexion, compte-tenu de la relative faible épaisseur de la couche de revêtement de métal, des fissures peuvent apparaître dans cette couche. Ces fissures du revêtement des fils d'aluminium est problématique puisqu'il peut entraîner une corrosion galvanique entre le cuivre et l'aluminium.When crimping an end lug or a connection, given the relatively small thickness of the metal coating layer, cracks may appear in this layer. These Cracks in the coating of aluminum wires are problematic since they can lead to galvanic corrosion between copper and aluminum.

Pour résoudre ce problème, l'invention propose un câble de transport d'énergie électrique comportant un noyau central de fils d'aluminium recouverts d'un revêtement métallique et une couche périphérique constituée au moins partiellement de fils de cuivre, lesdits fils d'aluminium et de cuivre étant recouverts d'une couche de revêtement en métal ou alliage métallique présentant une différence de potentiel galvanique avec l'aluminium positive et inférieure ou égale à 300mV, sous brouillard salin tel que défini dans la norme européenne NF EN 60068-2-1, caractérisé en ce que l'épaisseur de la couche de revêtement des fils d'aluminium est supérieure à celle de la couche de revêtement des fils de cuivre.To solve this problem, the invention proposes an electric power transmission cable comprising a central core of aluminum wires coated with a metal coating and a peripheral layer made at least partially of copper wires, said aluminum wires and of copper being coated with a coating layer of metal or metal alloy having a galvanic potential difference with positive aluminum and less than or equal to 300mV, under salt spray as defined in the European standard NF EN 60068-2- 1, characterized in that the thickness of the coating layer of the aluminum wires is greater than that of the coating layer of the copper wires.

Grâce à l'invention, le câble ne perd pas sa résistance électrique de contact après 240 heures de soumission à un brouillard salin.Thanks to the invention, the cable does not lose its electrical contact resistance after 240 hours of submission to a salt spray.

Selon un mode de réalisation préféré, ladite couche de revêtement est en étain.According to a preferred embodiment, said coating layer is tin.

Une telle épaisseur de la couche de revêtement des fils de cuivre permet d'éviter qu'ils soient apparents, sachant qu'une fissure dans cette couche est peu problématique, et une telle épaisseur de la couche de revêtement des fils d'aluminium assure l'absence de fissure dans cette couche, lors d'un sertissage.Such a thickness of the coating layer of the copper wires makes it possible to avoid them being apparent, knowing that a crack in this layer is not very problematic, and such a thickness of the coating layer of the aluminum wires ensures absence of crack in this layer during crimping.
