The invention relates to the technical field of high-voltage transmission lines, in particular to a novel crossed transposition tower. The novel crossed transposition tower comprises a tower body. A T-type earth wire cross arm is arranged at the top end of the tower body, upper layer wire cross arms shaped like an inverted Chinese character 'xia' are arranged below the earth wire cross arm, and lower layer wire cross arms shaped like a Chinese character 'shang' are arranged below the upper layer wire cross arms shaped like the inverted Chinese character 'xia'. Each upper layer wire cross arm shaped like the inverted Chinese character 'xia' is composed of upper cross arm bodies on the two sides of the tower body and a lower cross arm body on the left of the tower body, and each lower layer wire cross arm shaped like the Chinese character 'shang' is composed of an upper cross arm body on the right of the tower body and lower cross arm bodies on the two sides of the tower body. According to the novel crossed transposition tower, the arrangement mode of the lower layer wire cross arms shaped like the Chinese character 'shang' and the upper layer wire cross arms shaped like the inverted Chinese character 'xia' is adopted, the wire cross arms are reasonably utilized, the service conditions of the tower are lowered, the height of a tower head is reduced by about 25%, project investment is saved, the cross arms are symmetrical, the overall structure is more stable, occupied area is reduced, and influence caused by the position of the tower is little; due to the T-type earth wire cross arm, while the lightning protection range is guaranteed, earth wires are prevented from being crossed, and thus the size of the tower head is further reduced.
