The invention discloses a multi-section pole tower and belongs to the field of power transmission line pole towers. The multi-section pole tower comprises a first pole body, a second pole body and a third pole body; the first pole body, the second pole body and the third pole body are sequentially connected; and the radius of the second pole body is less than the radius of the first pole body andthe radius of the third pole body. A pole body of the pole tower is divided into three sections, wherein the radius of the section, provided with a cross arm, of the pole body is less than the radiusof the other two sections of the pole body, the radius of the pole body is related to the size of the cross arm, thus when the radius of the pole body is decreased, the size of the cross arm is decreased correspondingly, and accordingly, the length of a power transmission line and the using quantity of the power transmission line are decreased.
