Claim Text:
1. A self-supporting cable comprising an outer portion and an inner portion, the inner portion comprising at least one insulated conductor and the outer portion comprising a first inner surface and an external surface, the external surface being arranged to engage with a suspension arrangement, wherein the inner portion comprises a first outer surface, the first outer surface abutting against the first inner surface, the outer portion comprises an outer layer and a metal tape adhered to the outer layer, wherein the outer layer comprises the external surface, and wherein the metal tape comprises the first inner surface; wherein at least in a point, line, or region of the self-supporting cable subjected to a radially inwardly directed force (F) the first inner surface and the first outer surface are arranged in frictional engagement with each other for transfer of a force along a longitudinal direction of the self-supporting cable from the outer portion to the inner portion; wherein the metal tape has a thickness that is: (i) from around 50 μm to around 500 μm, or (ii) from around 5 μm to around 50 μm and the metal tape is bonded to a polymer layer, or (iii) lower than around 5 μm and the thickness of the polymer layer is from around 50 μm to around 200 μm; and wherein a coefficient of friction between the first inner surface and the first outer surface is at least 0.4.
