The cable comprises one or more fiber bundles having 100 or more fibers per bundle, the diameter of the fibers having a value smaller than 20 micrometers, and the fibers preferably consisting of an alloy containing titanium as base metal and, in addition, at least one metal from the group including niobium, tantalum, zirconium, chromium, molybdenum, iron and aluminum. The bundle may be wound around the longitudinal axis of the cable and/or plaited with other bundles. Furthermore, the fibers of a bundle may be twisted (snaked), circumstances permitting. Each bundle and its fibers should, however, run to advantage in a way to have the length of the bundle as well as the length of each fiber of the bundle preferably be not more than 50% and, for example, not more than 30% longer than the cable. The fibers may be bent down to very small radii of curvature, without any fatigue failures taking place, while a relatively low electrical resistance of the cable may be achieved. The fibers are covered on their outer surfaces by a metal oxide layer, effective to insulate the fibers, in addition to the normally provided rubber-elastic insulation.
