The utility model discloses a four loop cable cut -off strain insulator tower, including the body of the tower, be equipped with top layer ground wire cross arm on the body of the tower, go up two wire cross arm, lower pair time wire cross arm and bottoms of returning and assist the cross arm, top layer ground wire cross arm, going up two wire cross arms that return and arranging the both sides cross arm from body of the tower side perpendicular to circuit directions, upper and lower direction is unanimous, lower pair time wire cross arm, the supplementary cross arm of bottom are the T style of calligraphy and arrange that upper and lower direction is unanimous, and adjacent both sides cross arm contained angle is 90 degrees. Return the wire cross arm lower pair each slightly the portion all be connected with cable lift kits, all be connected with on each cable lift kits and foretell the style of calligraphy cable and draw terminal down. This tower is applicable to the overhead transmission line corner, regard as the corner number of degrees 45 degrees 90 the angle tower of degree can be used to four return circuit unilaterals or two side and cut -offs, should be close to the tangent tower construction, compares with present scheme and has saved a basic shaft tower, has reduced construction cost, has reduced area.
