摘要： The present invention relates to problems how to keep cable arrangement functional, or at least make the damage as little as possible, after being exposed to different types of mechanical overloads. The problems are solved by methods and arrangements in which the securing means and the contact material of the securing means are arranged so that the cable can slide through the securing means when it is exposed to mechanical overloads.

摘要： 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).

摘要： An electrical cable with three insulated conductors, a tube for an optical cable, a strip of elastic material embedding the tube, and a jacket. When the cable is handled, e.g. suspended between poles or dredged into the ground, the tube can be deformed by external forces. This makes it impossible to blow or float the optical cable into the tube. The tube is protected by the strip, and especially by the strip having a flat interval in proximity to the tube. External forces will mainly deform the strip at the ends of the interval and less of the forces will hit the tube. The deformation sets up an interior pressure in the strip that acts in sideward direction on the tube and contributes to keep it round and non deformed.

摘要： 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).
