The invention relates to the technical field of power systems, in particular to an outer wedge type assembled current diverting line. The outer wedge type assembled current diverting line comprises an outer wedge type assembled line clamp and steel-cored aluminum strands. The outer wedge type assembled current diverting line comprises a part for gripping an original wire and a part for connecting a new current diverting line which are connected. The part gripping the original wire is a special wire clamp formed by a sleeve and a wedge. The part for connecting the new current diverting line uses a hydraulic compression tube to be connected with the current diverting line. The outer wedge type assembled current diverting line has the advantages that the line is convenient to mount and demount, safe and reliable, reasonable and simple in structure, high in practicality, convenient to machining and mount, and advanced in process; the line satisfies regulated requirements such as mechanical strength and electric strength while maintenance is not needed; optimal gripping strength and contact area are achieved, and the line can pass a tension test, a vibration test, a temperature rise test and the like; contact evenness is guaranteed, problems such as node overheat and corona discharge are avoided, personal safety of operators is effectively guaranteed, and actual production requirements are satisfied.
