The invention relates to a method or device special for assembly or maintenance or repairing or disassembly of cables or electric wires, in particular to a lifting device of multiple divided conductors of a transmission tower. The lifting device of the multiple divided conductors of the transmission tower comprises a first lifting mechanism, a second lifting mechanism and special clamps, the two lifting mechanisms are connected to a wire clip connection board supporting the multiple divided conductors through the special clamps, the wire clip connection board, a suspension wire clip and the multiple divided conductors are lifted integrally, and each special clamp is composed of two fixing boards and a connection board welded between the two fixing boards. The lifting mechanisms are arranged in an air interval space between the transmission tower and the multiple divided conductors. Lifting force is generated through a bidirectional lead screw nut or a hoist crane or an electric/pneumatic/hydraulic cylinder structure. The upper ends of the lifting mechanisms are hung to a cross arm of the transmission tower; the lower ends of the lifting mechanisms are connected to the upper ends of the fixing boards; the lower ends of the fixing boards are hinged to the upper end of the wire clip connection board through hinge shaft holes. The device is simple and flexible in structural mode, convenient to use and capable of meeting the requirements of the maintenance, overhauling and power failure operation of an extra-high voltage transmission circuit.
