The invention describes a flexible multicore electrical cable with a central supporting member ( 3 ), several cores ( 1 ) that includes insulated fine-strand conductors and surround the supporting member ( 3 ), and a plastic sheath ( 5 ), wherein the central supporting member ( 3 ) includes a torsionally rigid steel cable ( 3 a), which is provided with an outer layer of insulation ( 3 b). The steel cable ( 3 a) includes a core strand ( 6 ), a first course of several strands ( 7 ) stranded on the core strand ( 6 ), and a second course of several strands ( 10 ) stranded on the first course, wherein the direction of lay and/or the length of lay of the strands ( 10 ) of the second course is different from the direction of lay and/or the length of lay of the strands ( 7 ) of the first course.
