Abstract
A cable comprises at least two cores stranded together, an expanded inner jacket layer, a substantially circular metallic armor partially contacting the inner jacket to form unfilled interstices outside the inner jacket, and a polymeric outer jacket. The expanded inner jacket substantially takes the shape of the periphery of the stranded cores, providing a non-circular cross section for the expanded inner jacket. A method of producing a cable comprises providing at least two cores, expanding a polymeric material, extruding the expanded polymeric material around the cores, and allowing the expanded polymeric material to collapse onto the cores. A substantially circular metallic armor is applied, resulting in a plurality of unfilled voids between the inner jacket and the metallic armor. An outer jacket is extruded on the metallic armor.
