• Conductors for overhead lines - Aluminium and aluminium alloy wires for concentric lay stranded conductors

  Käsitlusala:

  This standard is applicable to aluminium and aluminium alloy wires for the manufacture of concentric lay overhead electrical stranded conductors with or without gap(s) for power transmission purposes. It specifies the mechanical and electrical properties of round and formed wires for equivalent diameters up to 5,00 mm for thermal resistant alloys, and up to 5,50 mm for other aluminium alloys. The various alloys and their designations are listed in Table 1. For calculation purposes the values listed in Table 1 shall be used.
