1.Application

ACSR Conductor is mainly used as bare overhead transmission cable and as primary and secondary distribution cable. These conductors are formed by several wires of aluminum 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 of aluminum. Normally these conductors have a Galvanized steel core of 1, 7, 19 or 37 wires, surrounded by concentric layers of aluminum wires. The diameters of the steel and aluminum wires can be alike or different. By varying the relative proportions of aluminum and steel ratios, the ideal conductor can be produced for any particular application. In this way , if a high tensile strength conductor is required, the number of steel wires can be increased until the required strength is reached . When a conductor with high current carrying capacity and a comparatively low strength is required, this is attained with high aluminum content.
