Abstract
A method is provided for maintaining an electric cable, said electric cable comprising at least one electric conductor surrounded by an outer sheath, said outer sheath containing an insulating oil distributed around said electric conductor, such as a fluid-oil cable or an oil-filled cable. A drying oil, selected so as to solidify upon contacting the air, is added to the oil of the cable for sealing off any accidental oil leak through an outer sheath of the electric cable.
