This utility model provides a fade-resistant 3D number plate for overhead power line towers, relating to the field of line number plates. The fade-resistant 3D number plate includes a mounting plate with multiple sets of through holes on its surface. These through holes form the information to be displayed on the mounting plate. Color bars are inserted into the through holes, protruding from the mounting plate and extending to its front. This fade-resistant 3D number plate for overhead power line towers, by setting multiple through holes in different positions to form the information to be displayed, and by placing color bars inside the through holes, displays the information through color contrast between the color bars and the mounting plate. Even if the color bars are worn away by wind and sand, exposing the internal material, the internal material remains the same color as the color bar itself, thus achieving a fade-resistant effect.
