The utility model provides a single loop that adopts V style of calligraphy combination cluster cut -offs steel pipe shaft tower. It includes body of the tower, top layer ground wire cross arm, upper wire cross arm, middle level wire cross arm, lower floor's wire cross arm, top layer ground wire cross arm cut -offs the side from the body of the tower dorsad to be arranged on one side the perpendicular to target and cut -offs the cross arm of circuit, arranges triumph cross arm on one side towards cut -offfing the side, upper strata wire cross arm cut -offs line arrangement both sides cross arm from the parallel target of body of the tower, cut -offs line arrangement cross arm on one side towards cut -offfing the perpendicular target of side, middle level wire cross arm cut -offs line arrangement both sides cross arm from the parallel target of body of the tower, cut -offs line arrangement both sides cross arm from the perpendicular target of body of the tower, lower floor's wire cross arm cut -offs line arrangement both sides cross arm from the parallel target of body of the tower. The utility model discloses only adopt a basic shaft tower to realize the problem that the single loop cut -offs, reduced newly -built shaft tower quantity, form the two return circuits of different phase sequences range after cut -offfing and continue to walk the line, reduce and lead line space electric field strength, avoid two return circuits to divide the use of branch, do not change the wire arrangement form of adjacent shaft tower, reduced the possibility that adjacent tower was transformed.
