New and improved vibration damper, primarily for power cables, is disclosed and comprises two damper elements having interfaces of vibrational energy absorbing materials in the nature of rubber, and two rigid absorber arm and weight assemblies pivotally connected thereto. In use, vibrational energy is transmitted from the cable by, and under the vibrational energy absorbing restraint of, the interfaces to the absorber arm and weight assemblies for damping of the same. The absorber arms are of unequal length to provide two natural frequencies for the damper, and the vibration weights are readily removable for replacement by weights of different mass to adapt the same basic vibration damper to a wide variety of applications.
