ABSTRACT:
An electrical cable, for communication purposes, having spaced-apart, insulated electrical conductors, between each two of which is disposed a portion having a block-shaped cross section, with a plurality of tension-absorbing elements of high-strength fibers being disposed in this portion. The problem in the past has been that the flexibility of the cable is limited by the specific breaking elongation of the fibers. To resolve this problem, and to improve the flexibility primarily for termination and connection purposes, the cable has an arbitrary number of tension-absorbing elements which are arbitrarily distributed, even in an unsymmetrical manner, in the tension-absorbing block of the cable. The electrical conductors are placed on the bending axis of the cable, which is determined by the tension-absorbing elements, the effect of the conductors on the bending properties, and the casing material. The conductor axis is shifted to such an extent that it coincides with the bending axis which is optimum with regard to the overall system, so that the transverse central planes of the conductors are disposed in the bending axis. This arrangement is also possible for a cable which has more than three parts.
