fiber layer 14 colored with the signal color serves to indicate wear in the event of damage to outer cable 20 and to inhibit friction between the cable core and cable jacket the copper fibers introduced into outer cable jacket 20 in order to impart electrical conductivity to the cable structure also contribute simultaneously to a reduction in wear due to abrasion of the synthetic fibers corresponding to the first and second embodiments outer cable jacket 20 is once against sealed with a flexible resin system to prevent penetration of water and dirt the embodiment of the invention depicted in fig4 comprises as an electrically conductive insert a single wire 22 forming the cable core around which the twelve load bearing synthetic fiber strands 12 made of dyneema are braided once again only synthetic fiber strands 12 that are braided with one another are load bearing the cable is additionally equipped with a colored coating 24 in the present case embodied as a polyurethane coating and wire 22 is encased in a plastic sheath 26 while plastic sheath 26 protects the wire from chemical influences the colored coating 24 serves as a wear indicator since corresponding abrasion of the colored coating 24 enables easy visual checking of.
