Tangent tower for 60-millimeter heavily iced area of +/-800-kilovolt ultrahigh-voltage direct current line

The utility model provides a tangent tower for a 60-millimeter heavily iced area of a +/-800-kilovolt ultrahigh-voltage direct current line. The tangent tower comprises a tower leg, a tower body and a tower head, wherein the tower body is a twice slope-changeable tower body; the tower head is shaped like a cleat and consists of a lead wire cross arm and a ground wire bracket; the lead wire cross arm is positioned on the tower body and extends from two sides of the tower body; an opening type trapezoid cross arm is adopted, and the body part adopts a twice changed slope; a lead wire on the lead wire cross arm is horizontally arrayed; a lead wire insulator string is a V-shaped string. The tangent tower for the 60-millimeter heavily iced area of the +/-800-kilovolt ultrahigh-voltage direct current line has the beneficial effects that by the adoption of the V-shaped string arrangement, the width of a line corridor can be reduced, and damage to the environment is relieved; furthermore, the tower weight is controll
