ABSTRACT:
A device for changing an electric wire and method for distributing power without cutting off power supply has developed for replacing the live electric line on the electric poles, relocating the electric poles and alteration of the power distribution route. Replacement operation of the live electric wire is sequentially performed by connecting new wire and separating old wire by the wire changing device mounted on each electric pole without using bypass cable. The wire changing device comprises a cross-arm fastening unit, wire replacing unit and axial-rotating unit having a central arm fixture, axial shaft, arm coupling and position locking unit. The wire changing method comprises the steps of: mounting the wire changing device on each electric pole, replacing new and old wires without cutting off power supply, arranging the wire space, installing and tightening the new wire on each LP insulator of the electric pole, and removing the separated wire.
