The invention discloses a 'T'-shaped combiner for an electrical power insulating rod. The 'T'-shaped combiner comprises a penetrating movable pipe and a fixed supporting pipe, wherein the penetrating movable pipe and the fixed supporting pipe are positioned in the same plane; the pipe wall of the outer side of the penetrating movable pipe is hinged to one end of a connection plate; the other end of the connection plate is hinged to the pipe wall of the outer side of the fixed supporting pipe; the length of the connection plate is greater than that of the penetrating movable pipe; two connection plates are arranged in the same plane; the plane where the two connection plates are positioned is perpendicular to the plane where the penetrating movable pipe and the fixed supporting pipe are positioned. According to the 'T'-shaped combiner for the electrical power insulating rod, the penetrating movable pipe in the combination rotates freely. Due to the rotation of the penetrating movable pipe, the insulating rod can extend freely; in a use process, the penetrating movable pipe and the fixed supporting pipe are in a T shape; the fixed supporting pipe serves as a stable supporting device. The 'T'-shaped combiner for the electrical power insulating rod is used stably and safely, and the use range of the insulating rod is expanded.
