The utility model discloses a repair pipe used for an aluminum-clad steel core aluminum stranded wire. The repair pipe comprises an aluminum pipe and a drawer. The aluminum pipe is provided with a sliding groove in the axial direction, and the sliding groove matches the drawer. The opening distance on the outer surface of the aluminum pipe, of the sliding groove is smaller than the opening distance on the inner side of the aluminum pipe. The outer surface of the drawer is a cambered surface. The inner surface of the drawer and the inner surface of the aluminum pipe are semicircular cambered surfaces. After the drawer is butted with the sliding groove in a drawer manner, the inner surface of the drawer and the inner surface of the aluminum pipe form a complete circular cambered surface, and the outer surface of the drawer and the outer surface of the aluminum pipe form a complete circular cambered surface. The aluminum pipe and the drawer are made of heat-resistant aluminum alloy. The repair pipe used for the aluminum-clad steel core aluminum stranded wire is simple in structure, flexible in assembling, convenient to use, capable of being reliably connected with the aluminum-clad steel core aluminum stranded wire in a pressing manner, and relatively good in repair effect.
