Description
Technical Field
The invention relates to the field of cables, in particular to a flexible cable.
Background
In international application WO 97/40504 a self-supporting electrical cable is described having a shielding tape around the insulated electrical conductors, which effectively protects the cable when it is suspended from a fixed point. The cable may be provided with a tube in the above-mentioned region. International application WO 2004/006272 describes an electrical cable having a shield strip of partially conductive material running along the cable in the region between an insulated electrical conductor and a cable jacket. The conductive wire runs in the strip along its entire length and forms an effective guard to cut the cable voltage when it is penetrated by a conductive object. Also, a tube may be arranged in such a cable.
Cables of the above-mentioned type are well suited for their purpose, but problems arise if they are equipped with a tube for an optical cable. The tube may be deformed when the cable is manufactured or handled, and such deformation makes it impossible to install the optical fiber. Such deformations may occur, for example, when the cable is suspended along the cable by a suspension device, or is held at the cable end by a lashing device. Cables buried in the ground may be deformed by stones and even cables placed on the sea bottom may be subjected to forces that deform the pipe. The tube can be made very strong so that it withstands deformation forces. This would have the following disadvantages: the tube becomes very rigid and all cables will be rigid and difficult to handle.
