Abstract
A cable, in particular a cable for the at least partial transmission of electrical energy, comprising several, in particular three, phase cores and at least one further core, in particular a protective core, is proposed, wherein the several phase cores are stranded to form at least one phase bundle and the at least one further core runs outside the at least one phase bundle in the cable.
Claims13
A cable for at least partial transmission of electrical energy, comprising:
- multiple phase cores that are stranded to form a phase bundle, the phase bundle being electrically arranged with respect to a central longitudinal axis of the cable;
- at least one further core running outside the phase bundle in the cable, the at least one further core and any further cores of the at least one further core in the cable are wound around the phase bundle with a direction of lay opposite to the direction of lay of the multiple phase cores in the phase bundle;
- wherein the cable is designed to be at least electrically symmetrical at least with respect to a respective capacitive and/or inductive coupling of the at least one further core with in each case one of the multiple phase cores, in that the capacitive and/or inductive couplings between the at least one further core and in each case one of the multiple phase cores are at least approximately equal in magnitude;
- and
- an inner layer arranged eccentrically in the interior of the cable with respect to the central longitudinal axis of the cable, wherein the phase bundle is disposed in the inner layer, and wherein the phase bundle is arranged to move around the central longitudinal axis of the cable such that an orientation of the eccentricity of the phase bo dle changes with respect to the central longitudinal axis of the cable along a longitudinal extension of the cable.
