ACSR conductor
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 sore 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 producted 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 a high aluminum content.
Properties
In comparison with copper, these conductors have considerable technical and economical advantages in the installation advantages in the installation of overhead lines.
Its characteristics, and low weight, combined with its high breaking strength, are gathered which makes it possible to bave large span runs, without having to revert to excessive mechanical tresses or to heavy metallic towers.
Due to the greater diameter of the conductors, electric losses by the corona Effect are greatly reduced.
Buy making use of these properties Economical electric energy. Transmission is attained at very High voltages and distances.
Main applications
Overhead lines of medium, high and very high voltages.
