The utility model provides a two return circuits become exhales high shaft tower. It includes body of the tower, top layer ground wire cross arm, top layer ground wire cross arm is the one deck altogether, arranges the both sides cross arm from the newly -built circuit direction of body of the tower perpendicular to, upper strata wire cross arm divides the three -layer, and one deck both sides cross arm is arranged from the newly -built circuit direction of body of the tower perpendicular to in each layer, the supplementary cross arm in middle level has a multilayer, and one deck both sides cross arm is arranged from the newly -built circuit direction of body of the tower perpendicular to in each layer, lower floor's wire cross arm is the three -layer altogether, and one deck both sides cross arm is arranged from the newly -built circuit direction of body of the tower perpendicular to in each layer. The utility model discloses a basic shaft tower has realized that two return circuits become and has exhaled high boring and cross over, has reduced the elder generation and has striden cross link transformation in the driller's journey of back, has put cable underground and the probability of single two return circuits transform, has avoided the power failure of cross link, has increased the electric wire netting reliability, has reduced the construction cost, has further compressed simultaneously to bore more the newly -built circuit of shelves and lead ground wire pair ground distance.
