Several wires in aluminum conductor cables fractured within 5–8 years of, service Alaskan tundra. The were comprised of 19-wire strands; the alloy 6201-T81. Visual and metallographic examinations cold-upset pressure weld joints established that fractures caused by fatigue loading attributable to wind/thermal factors at joints. grain flow was transverse wire axis, rendering notches sensitive loa...

Modern technological solutions in electrical applications require, above all, high energy efficiency. This means that such applications, materials with the highest possible conductivity should be used for conductive elements. Of all metals, copper is natural choice. Copper cables or wires networks and installations provide better thermal guarantee reliability - which translates into quality of ...
