<p><P>PROBLEM TO BE SOLVED: To make it hard to form nicking of steel core aluminum stranded wire, and eliminate winding application working of a spiral rod at a high place. <P>SOLUTION: At the outer periphery of the steel core aluminum stranded wire 1 in which hard aluminum element wires 2 are installed at the outermost layer, the wires are twisted at a shorter twisting pitch than that of the hard aluminum element wires 2 in the reverse direction of the twisting direction, and elongation characteristics of spiral wires 3 of aluminum covered steel wires are made larger than those of the steel core aluminum stranded wires 1, and the hardness of aluminum cover of the spiral wires 3 is made smaller than that of the hard aluminum element wires 2. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
