Flexible multicore electrical cable

Abstract

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 (3a), which is provided with an outer layer of insulation (3b). The steel cable (3a) 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.
