This electric current transmission cable comprises a non-anodized bare conductor (10) based on aluminium or aluminium alloy exhibiting a hydrophilic external specific surface area (S) intended to be in contact with the atmospheric medium and an interior volume (V) intended to conduct an electric current. The external specific surface area (S) of the bare conductor (10) exhibits a first roughness parameter (R), defined as arithmetic mean deviation measureable by profilometry of peaks and troughs with respect to a predetermined mean profile over a reference length or surface, greater than or equal to 1.9 µm. Furthermore, the interior volume (V) of the bare conductor (10) exhibits, down to a depth (P) of at least 300 nm with respect to the external specific surface (S), an oxygen doping of its aluminium-based or aluminium-alloy-based components according to an amount greater than or equal to 20%. |
