The utility model relates to an adjustable conductor interphase interval stick and belongs to the technical field of power transmission and transformation. A beam (3) is fixed on an inner ring of a sub-conductor interval stick (1), which is corresponding to a conductor collet (2); a locating hole (4) is arranged on a plane of the beam (3) and the sub-conductor interval stick (1), the two ends of a connecting plate (5) are respectively articulated with an adjustable plate (6); the other end of the adjustable plate (6), corresponding to the space among all the locating hole (4), is provided with more than three adjustable holes (7), the locating hole (4) on the he beam (3) and the sub-conductor interval stick (1) is fixedly connected with an adjusting hole (6) on the adjustable plate (6) by a bolt (8), and the middle part of the connecting plate (5) is connected with a spherical hinge of an insulator end fitting (9). The interval stick can conveniently suit and make up the installing error of conductor arc sag; besides, the installation of the sub-conductor interval stick (1) is very convenient; the interval stick has simple structure, convenient manufacturing, strong commonality and wide application range.
