The invention discloses an annular multi-split vibration-damping galloping preventer which comprises a closed annular tube. The external surface of the annular tube is provided with a plurality of lead clamps. The annular tube is internally provided with a vibration damping system. Furthermore antifreezing and anti-corrosion liquid is filled in the annular tube. According to the annular multi-split vibration-damping galloping preventer, integrated design of a spacer rod a multi-split galloping preventer is realized. The vibration damping system which is arranged in the closed annular tube can restrain the vertical vibration amplitude of the lead to a certain extent by means of self weight for preventing an overlarge tension load of the lead because of excessive deformation of the lead on one hand; and on the other hand, the vibration damping system can generate resonance before a power transmission lead for consuming system energy, thereby reducing torsion and vibration degrees, and prolonging service life of a lead system. Through reducing torsion amplitude of the multi-split lead in galloping, the annular multi-split vibration-damping galloping preventer has functions of effectively restraining vibration amplitude, improving a lead operation environment, and prolonging service life of the lead.
