Similarity laws governing the internal damping of stranded cables in transverse vibrations are based on the assumption of hysteretic loss factor associated with the flexural rigidity of the cable and the assumption that this loss factor is the same for all cables of the same construction. These laws are derived from the basic cable differential equation. The proportionality factors, the exponents of the various parameters in the laws, are obtained from the experimental results of a typical member of a family of similar cables. The same set of laws has been found to apply very well to ACSR (aluminum conductor steel reinforced) conductors having the same number of strands and fairly well to all ACSR conductors. Other families of cables, such as ACAR (aluminum conductors aluminum reinforced), steel cables, etc., could each have their own set of similarity laws, which would all look alike.>
