Patent ID: 7387294

Claim:
A method for changing a live electric wire on electric poles without cutting off power supply by using a wire changing device, the method comprising steps of: mounting a wire transfer mechanism on each cross arm of terminal poles, strain poles and pin long columns, providing a workspace using a cross arm extension means to temporarily relocate old wires onto said workspace of the cross arm, securing and protecting live electricity of said old wires while new wires are temporarily placed on each LP insulator of pin long column, installing and fixing said new wire on each LP insulator of pin long column and adjusting said new wire tensions by stranding and pulling through a stranding mechanism mounted on an upper portion of the LP insulator, adjusting wire intervals by a wire space maintainer for securing safe distances between the installed new wires and preventing an accidental contact with the new wires and removed old wires during the wire stranding process, switching electric power from the old wires to the new wires without cutting off power supply by an uninterrupted electricity method, and removing the old wires separated from the electricity supplying lines.
