Abstract: An electric submarine power cable, in particular for use in hydrocarbon pipeline heating systems and adapted to be installed as a piggyback cable on the pipelines, having a multi-wire stranded conductive core with an outer insulation and at least one outer protective sheath as well as armoring means. The armoring means are incorporated in the conductive core as integral tensile strength wire elements. Moreover, a hydrocarbon pipeline heating system as such, having this submarine power cable.

Abstract: The present invention relates to an electric submarine power cable, in particular for use in hydrocarbon pipeline heating systems and adapted to be installed as a piggyback cable (12) on said pipelines (10), comprising a multi-wire stranded conductive core (2) with an outer insulation (4) and at least one outer protective sheath (8) as well as armouring means. The armouring means are incorporated in said conductive core (2) as integral tensile strength wire elements (1). Moreover, the invention relates to a hydrocarbon pipeline heating system as such, comprising this novel submarine power cable.
