<p>PROBLEM TO BE SOLVED: To eliminate additional parts for protrusions and fins on a wire, by requiring a special tool and eliminate the removal work of fins, etc., on a high place by a method wherein the fins, protrusions, etc., on the portions of the wire which correspond to the holding parts of the wire having the fins, protrusions, etc., and correspond to the holding parts at the wire tightening are removed. SOLUTION: Protrusions 1 on a dead-end clamp position making part 4 are removed over a length corresponding to the dead-end clamp and, before and after that position, protrusions 1 on portions corresponding to come along attaching positions are removed over lengths, corresponding to the come alongs to form portions 5 having smooth surfaces 5. Further, protrusions 1 on portions of suspension clamp position markings 7 are removed over a length, corresponding to the suspension clamps and armor rod winding parts to form portions 6 having smooth surfaces. With this constitution, additional parts for the fins are eliminated, a special tool is not required, and further, removing work on a high place can be eliminated.</p> |
