A vibration damper for cables utilizing the frictional properties of a close-wound spiral spring, that is, a spring wound in spiral form from a flat strip and having contacting faces. Vibrational energy is dissipated in the spiral spring by the lateral motion of the turns of the spring relative to one another. Typically, two spiral springs are contained in a housing suspended from a cable conductor. The housing of the device including such supplementary weight as required by the design forms an inertial mass which tends to remain fixed in space. During vibration of the cable, the turns of the spring are forced to move up and down against each other and the frictional resistance to their motion dissipates the vibrational energy in the cable, thereby reducing the vibration amplitude to a safe low level.
