A cable includes a first wire-shaped metal conductor, a second metal conductor extending a predetermined distance away from and parallel to the first conductor, and a matrix made of a PTC material extending along the conductors, touching the latter and connecting them to one another electrically, with temperature-dependent electrical resistance and a positive temperature coefficient. At least one electrically insulating outer insulation layer surrounds the conductors and the matrix annularly. At least a third and a fourth metal conductor extend a predetermined distance away from and parallel to the first conductor, touch the matrix and are connected electrically by means of the latter to the first conductor, the second, the third and the fourth conductor being made in a wire shape and, considering the cross-section of the cable, being arranged distributed evenly over a circular track surrounding the first conductor.
