750kV two-circuit three-column two-door type drill crossing tower

The invention discloses a 750kV two-circuit three-column two-door type drill crossing tower which comprises two middle cross arms. The two ends of the middle cross arms are symmetrically connected with side cross arms correspondingly. Side ground wire frames and a middle ground wire frame which are inclined outwards are connected to the upper planes of the two ends of the side cross arms and the cross arm intersection correspondingly, the ground wire frames are connected with the middle cross arms on a middle stand column, and the tail ends of the ground wire frames are bent inwards and provided with ground wire hanging points. The left side cross beam and the right side cross beam are sequentially arranged below the ground wire frames from left to right, the two side cross beams are divided into the left middle cross beam and the right middle cross beam through stand columns, and the stand columns and the middle stand column are connected to the lower planes of the two ends and the intersection of the left m
