The utility model provides a single loop becomes exhales high shaft tower. It includes body of the tower, top layer ground wire cross arm, post insulators, top layer ground wire cross arm comprises the both sides cross arm of perpendicular to circuit direction, the upper strata is strideed across the cross arm and comprises the one deck both sides cross arm and the unilateral cross arm of one deck of the newly -built circuit direction of perpendicular to, the supplementary cross arm in middle level comprises the multilayer both sides cross arm of the newly -built circuit direction of perpendicular to, lower floor's brill cross arm more comprises the one deck both sides cross arm of the newly -built circuit direction of perpendicular to. The utility model discloses reduce the probability that the elder generation strode in the driller's journey of back the cross link transformation and put cable underground, avoided the power failure of cross link, increased the electric wire netting reliability, reduced the construction cost, further compressed wire pair ground distance with boring leading of shelves more.
