Abstract
A self-supporting cable including an outer portion and an inner portion is provided, as well as a combination of a self-supporting cable and a suspension arrangement. The inner portion includes at least one insulated conductor and the outer portion includes a first inner surface and an external surface. The external surface is arranged to engage with a suspension arrangement. The inner portion includes a first outer surface, the first outer surface abutting against the first inner surface. The outer portion includes an outer layer and a metal tape adhered to the outer layer. The outer layer includes the external surface, and the metal tape includes the first inner surface. The first inner surface being of metal and adapted for, during local load, frictional engagement with the material of the first outer surface increases the effectiveness of a functional grip between first outer surface and first inner surface.
