Overhead bare stranded aluminum conductor steel reinforced acsr conductor
General
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.
Properties
In comparison with copper, these conductors have considerable
technical and economical advantages in the installation of overhead
lines. Its characteristics, and low weight, combined with its high
break1ng strength, are gathered which makes it possible to have
large span runs, without having to revert to excessive mechanical
stresses or to heavy metallic Towers. Due to the greater diameter
of the conductors, electric losses by the corona Effect are greatly
reduced. By 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.
