Abstract
L'invention concerne un câble de transport d'énergie électrique comportant un noyau central de fils d'aluminium (1) recouverts d'un revêtement métallique (1A) et une couche périphérique constituée au moins partiellement de fils de cuivre (2), lesdits fils d'aluminium (1) et de cuivre (2) étant recouverts d'une couche de revêtement en métal ou alliage métallique (1A, 2A) 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.The invention relates to an electric power transmission cable comprising a central core of aluminum wires (1) coated with a metal coating (1A) and a peripheral layer at least partially made of copper wires (2), said wires aluminum (1) and copper (2) wires being coated with a metal or metal alloy coating layer (1A, 2A) having a galvanic potential difference with the positive aluminum and less than or equal to 300mV, under salt spray as defined in European Standard NF EN 60068-2-1.
Selon l'invention, l'épaisseur de la couche de revêtement (1A) des fils d'aluminium est supérieure à celle de la couche de revêtement (2A) des fils de cuivre. According to the invention, the thickness of the coating layer (1A) of the aluminum wires is greater than that of the coating layer (2A) of the copper wires.
