Abstract (en)
[origin: EP2657944A2] The cable has an aluminum wires core (1) covered with a metal coating (1A) and a peripheral layer that is partially formed by copper wires (2) with diameter 0.2 mm to 2 mm. Aluminum wires and the copper wires are covered with a metal layer or metal alloy coating (2A) having a difference of electric potential with positive and less than or equal to 300mV aluminum under salt spray. Thickness of the metal coating of the aluminum wires is higher than that of the metal alloy coating of the copper wires.
