Support structure between electric wires of overhead wire



PROBLEM TO BE SOLVED: To provide a support structure between electric wires which can prevent the electric wire from trailing down simply and inexpensively. SOLUTION: A rope 1 having electrical insulation is laid between adjacent electric wires while keeping a predetermined interval among a plurality of parallel aerial electric wires 3a,3b,3c using a winding grip 4 wound aroujnd the electric wire. In addition, a distance L in the lengthwise direction of the electric wire between these extended insulating ropes 1,1 is set to the distance shorter than that from at least the aerial electric wires 3a,3b,3c onto the ground, so as to prevent the electric wires 3a,3b,3c from trailing down when the electric wire is disconnected by the extended insulating rope 1.
