Abstract
Described is a high-flex insulated electrical cable (11) for the carriages of flat knitting machines, this cable having two concentric multi-strand twisted layers (12, 13) each of which is comprised of a plurality of insulated individual strands (17) laid in long lay at the same twist angle. To enable a cable (11) of this nature to resist torsional stresses to an increased degree while retaining its shape and also to give it an extended length of life despite such torsional stresses, the individual strands (17) of each layer (12, 13) have an outer peripheral layer of resiliently deformable soft plastic (18, 19) injected therearound which penetrates into the gussets (22) which are formed between the individual strands (17).
