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, slippage 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) between the surfaces (112, 121) comprising at least on tape (511) with friction particles (512) where the friction obtained by the friction particles (512) is low enough to allow 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). |
