The invention discloses a bionic anti-erosion overhead conductor. Bionic V groove structures and bionic bump structures are arranged on the outer surface of the insulating material of the conductor in the longitudinal direction. The bionic V groove structures are distributed circumferentially on the insulating layer. The bionic bump structures are distributed on the ribs between adjacent bionic V groove structures. The cross section of each bionic V groove structure is an equilateral triangle, and the cross section of each bionic bump structure is a semicircle. By arranging the bionic V groove structures and the bionic bump structures on the surface of the material, the flow state of the gas-solid two-phase flow on the outer surface of the insulating material of the conductor can be changed, and the number of times that solid particles hit against the surface of the insulations material can be reduced. Under the action of air cushions inside the bionic V groove structures and at the interfaces between adjacent bionic bump structures, the collision speed of solid particles is reduced, the kinetic energy of solid particles for hitting against the surface of the conductor is reduced, and therefore, the erosion rate of the conductor under erosion of solid particles of different diameters is reduced, and the erosion resistance of the conductor is improved.
