The invention discloses an anti-seismic ultra-high voltage power transmission tower which comprises a concrete base and two locating grooves symmetrically formed in the inner side of the concrete base. A locating column is arranged between the two locating grooves. A tower support is arranged inside each locating groove, and the width of each tower support is smaller than that of the corresponding locating groove. High-strength springs are arranged on the side walls of the two sides of each tower support, and a fixing hole is formed in the middle of each tower support. A first main tower body and a second main tower body are arranged on the tower supports correspondingly, and the lower end of the first main tower body and the lower end of the second main tower body are inserted into the fixing holes of the corresponding tower supports. The tower supports are adopted, the first main tower body and the second main tower body are inserted into the corresponding tower supports, and concrete locating rings are adopted for fixation, so that installation is convenient, and reliability is high.
