The current invention relates to self-supporting cables that often are aerial mounted between cable fixing points (800) and where the conductors in the cables act as the bearing elements. In this type of cables, slip-page between the surfaces of different layers in the cable is undesirable. On the other hand, it must be possible to easily bend the cable, even for larger dimensions. Both these requirements are difficult to meet with the solutions from prior art. The present invention overcomes this by introducing an intermediate layer (130) in the cable (100) located between and adhered to the surfaces (112, 121) of the layers and having a frictional inner structure allowing the two surfaces (112, 121) to slip relatively each other in longitudinal direction enough so that the cable (100) can be bent but prevents the two surfaces {112, 121) from slipping in response to an inwardly directed radial pressure force (F) at the cable fixing points (800).
