Abstract

A flexible electric line for movable loads is specified which has at least two wires, in each case consisting of an electrical conductor and an insulation surrounding it, as stranded elements which are stranded around a core consisting of insulating material with dents extending in the longitudinal direction in which the stranded elements lie. In the core, a non-metallic tension- and compression-resistant carrier enclosed by a layer of insulating material is centrally arranged. The layer of insulating material consists of an impressible material remaining permanently elastic, which completely fills the internal interstices between the stranded elements, and it is surrounded by a sliding layer of a material having good sliding characteristics compared with the stranded elements.
