The utility model provides a special iron tower suitable for single time overhead line cable cut -offs draws terminal down including body of the tower, ground wire cross arm, upper wire cross arm, middle level wire cross arm, the supplementary cross arm of lower floor, cable lift kits and fore -telling style of calligraphy cable, the top of body of the tower sets up the ground wire cross arm, arranges the both sides cross arm from the perpendicular circuit orientation of body of the tower, upper strata wire cross arm is installed in ground wire cross arm below, arranges the both sides cross arm from body of the tower parallel circuit direction, in cross arm looks wire during the fixed strain insulator -string of portion hangs slightly, in the cross arm fixed fore -telling style of calligraphy cable termination of portion slightly. The beneficial effect of the utility model: the single time overhead transmission line cable that should be applicable to little corner cut -offs and draws strain insulator tower down, only need adopt a basic iron tower to realize that the cable cut -offs, and construction cost is lower, and area is less, does not change original line way arrangement, is fit for neighbouring tangent tower construction, can regard as the angle tower to use.
