The utility model relates to power equipment, in particular to an electric binding wire winder which is used for the butt joint of wires or leads during the overhaul and construction of power lines. The technical scheme of the utility model is that: the electric binding wire winder mainly comprises two parts, i.e. a working platform and a function control panel, binding wire-retaining tracks, motor, a reel and a strand splitter are arranged in the working platform, the motor and the binding wire-retaining tracks are fixed on the working platform, one side of the motor is connected with the reel, the binding wire-retaining tracks and the reel are arranged on the same straight line, and the strand splitter is arranged on the same side as the motor. The utility model has the advantages that: the electric binding wire winder can split the strands of aluminum strand wires, iron wires, copper wires and the like, is convenient to use, and is applicable to various models; on one hand, the labor intensity of on-site operators is decreased, and the working efficiency and on-site progress of binding wire fabrication are effectively increased; and on the other hand, because a binding wire can be orderly and uniformly wound, the standardization level of work is enhanced.
