Electric wire changing device for wire replacing works on electric poles and power distributing method without cutting off power supply

摘要

A method for distributing power has developed without cutting off power supplying while a live electric wire is replaced on the electric poles by using a wire changing device for replacing the electric line, 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.
