The invention provides a musical-scale type damping wire, and the damping wire is used for preventing an overhead line in an overhead transmission line from shaking because of breeze. The improvement lies in that the damping wire comprises side damping wire clamps and musical scale damping wire clamps, which are disposed on the overhead line. The side damping wire clamps are respectively disposed at two ends of the overhead line, and the musical scale damping wire clamps are disposed between the side damping wire clamps at intervals. Damping wires are respectively disposed between the adjacent side damping wire clamps and musical scale damping wire clamps, and between the musical scale damping wire clamps. Compared with the prior art, the damping wire achieves the stable holding of a conductor, and protects the conductor from being damaged or broken by overlarge pressure. The damping wire can meet the low-frequency, intermediate-frequency and high frequency vibration prevention requirements of a power transmission line (35kV or more), especially a conductor/ground line/OPGW of a UHV transmission line, is wide in vibration prevention frequency range, is remarkable in energy consumption effect, and is outstanding in vibration prevent effect.
