ALUMINUM COVERED STEEL WIRE AND OVERHEAD WIRE USING IT, OVERHEAD GROUND WIRE

摘要

PROBLEM TO BE SOLVED: To provide an aluminum covered steel wire having a high corrosion resistant performance and a mechanical strength suitable for electric wire usage and superior in economical efficiency while using an aluminum metal having a purity equivalent to regular overhead transmission line aluminum, and an overhead wire and an overhead ground wire using the same. SOLUTION: Since an aluminum covered part 11 containing at least one of manganese (Mn) of 0.1-2.9 wt.% and magnesium (Mg) of 0.4-5.6 wt.% in aluminum of purity of 99.7 wt.% or more and not exceeding 99.9 wt.% is provided as a covered material on the outer circumference of a steel wire 10, the aluminum covered steel wire uses aluminum with superior corrosion resistance, thereby, it has a mechanical strength suitable for electric wire usage and furthermore, an excellent economical efficiency can be given.
