According to the transmission conductor negative stiffness damper, damping is provided by additionally connecting the damper, the damping ratio is increased through the negative stiffness device, and the vibration reduction effect of a conductor model is achieved; according to the main components, the fixed magnet and the movable magnet are arranged side by side, and the interaction force between the magnets is basically linearly increased, so that a constant negative stiffness value can be ensured, the vibration reduction effect is obvious, the model loss is small, and the durability is high; the weight is light, transportation is convenient, and installation and maintenance are convenient; the whole transmission conductor negative stiffness damper is rigidly connected with the insulator string, so that the galloping vibration of the conductor can be effectively transmitted; the device is novel and unique in design and wide in application range, and has good popularization and application values and economic
