Abstract (en)

[origin: EP2693447A1] The method involves forming an alumina porous hydroxide layer (2) having pores. An elongated electric conductive element (1) is positioned around the hydroxide layer, where the conductive element is made of aluminum or alloy from aluminum. The pores of the alumina porous hydroxide layer are partially filled with a hydrophobic material (3) that is selected among fluorinated polymers, esters and the fatty-acids. The aluminum hydroxide layer porous is partially dissolved in an acid solution including chromic acid and phosphoric acid to form a hydrophobic coating (4). An independent claim is also included for an electric cable.
