The invention discloses a wind waving resisting device for a power transmission line. The device comprises a pawl type quick-loading anchor, an energy controlled release device, a conductor clamp andan anchoring machine. The wind waving resisting device for the power transmission line selects a bracing wire and an insulator string according to the relevant regulation in the use; after the insulator string, the energy controlled release device and the insulation bracing wire are connected, the insulator string is fixed to a corresponding location of a conductor through a non-destructive conductor clamp, and then the insulator bracing wire is anchored into the appropriate ground through the pawl type quick-loading anchor and the anchoring machine or the insulator bracing wire is directly pulled to the adjacent building. The wind waving resisting device disclosed by the invention can avoid the condition that the conductor and the pole tower are damaged by directly adopting a hard connection way for fixing the conductor through the insulator string and the insulator bracing wire.
