Double-apex cross arm and power transmission tower

The invention discloses a double-apex cross arm used for a power transmission tower. The power transmission tower comprises a tower head, a section of the tower head along the horizontal plane is a rectangular section, and the double-apex cross arm comprises two groups of sharp cross arms. Each group of the sharp cross arms comprises two groups of cross arm insulators distributed in a V shape along the horizontal plane, wherein one ends, at an opening position of the V shape, of the cross arm insulators are arranged on two adjacent sides of the rectangular section while the other ends are connected together to form a hanging point for hanging of wires. The two hanging points of the two groups of the sharp cross arms are positioned on the same side of the tower head. The double-apex cross arm is convenient to transport and maintain and low in cost. The invention further discloses the power transmission tower. 本发明公开种双尖横担，用于输电塔，所述输电塔包括塔头，该塔头沿水平面的截面为长方形截面，上述双尖横担具有两组尖横担，每组上述尖横担具有两组横担绝缘子，其沿水平面布置成V字型，两组上述横担绝缘子的位于V字型
