Flexible multicore electrical cable

abaThe invention describes a flexible multicore electrical cable with a central supporting member, several cores that includes insulated fine-strand conductors and surround the supporting member, and a plastic sheath, wherein the central supporting member includes a torsionally rigid steel cable, which is provided with an outer layer of insulation. The steel cable includes a core strand, a first course of several strands stranded on the core strand, and a second course of several strands stranded on the first course, wherein the direction of lay and/or the length of lay of the strands of the second course is different from the direction of lay and/or the length of lay of the strands of the first course.
