A cable, which is especially suitable as a suspension cable for cable railways, is described. The cable comprises a core (31) and several outer strands that surround the core and consist, for example, of several wires (32.1...32.6, 34.1 ... 34.12). The cable is characterized by an integrated antifreezing device (33.1 ... 33.6) which can be controlled from one end of the cable, preferably to prevent or specifically remove ice formations on an outer side of the cable. The antifreezing device (33.1 ... 33.6) is thereby preferably integrated in at least one of the outer strands, however, it can also be integrated in the area of the core (31) of the cable or in inserts that fill spaces between individual wires (32.1...32.6, 34.1 ... 34.12) of the cable. As the antifreezing device (33.1 ... 33.6) is preferably configured as resistance heating, its heat intensity can be accurately adjusted by the flow of the current. By means of the cross sections that can be changed along the cable or changeable material properties of the heating wires (33.1...33.6), it is possible to heat, especially intensely, in a concentrated manner, sections of the cable to be heated. In this way, the overall energy consumption of the device described can be as low as possible. Various constellations of strand wires (32.1...32.6, 34.1 ...34.12), of the core (31) of the cable and the antifreezing devices (33.1 ... 33.6) can occur, from the integration of the antifreezing devices (33.1 ... 33.6) in the core (31) of the cable to their positioning on parts of the outer surface of the cable.
