These conductors are formed by several wires of aluminium alloy and galvanized steel, stranded in concentric layers. The wire or wires which form the core, are made of galvanized steel and the external layer or layers, are made of aluminium alloy. Galvanized steel core consistn ormally of 7, 19, 37 and 61 wires. H.V. Overhead transmission and distribution linesSpecially recommended in, crossings, or where a very high tensile strength is needed.
