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.

Abstract: An electric cable for communication purposes, for instance a one-pair party station cable which is designed as twin cable and includes a cross-section-wise relatively flat envelope or cover of thermoplastics or elastomers and includes conductors arranged in spaced relationship to each other and also includes traction relief members in about the middle between the conductors. The traction relief members are embedded in the envelope or cover and are adapted to exert the traction forces exerted on the cable in the longitudinal direction thereof. The traction relief members include high-strength fibers arranged symmetrically with regard to the longitudinal central plane of the cable and with regard to the conductors. The enveloping substance includes thermoplastics or elastomers.
