ALL ALUMINIUM ALLOY CONDUCTOR ALUMINIUM ALLOY CONDUCTOR STEEL REINFORCED AAAC
AACSR
General
These conductors are formed by several aluminum alloy wires or either by several of these, with other wires of galvanized steel, stranded in concentric layers. The center wire or wires which form the core are made of alloy or steel and the outer layer are of
alloy.
Normally the compositions of these conductors are the same as the ones pertaining to the aluminum or aluminum-steel conductors.
In the case of alloy conductors. all the wire have the same nominal diameter and in the case of alloy conductors with a steel core. The diameter of the alloy and steel wires can be the same or different.
The basic composition of this alloy pertains to the Aluminum-Magnesium-Silicon group.
Which is also known in Europe as Almelec or Aldrey-After their drawing they must undergo a thermal treatment at a temperature of approximately 170℃.
Properties
As regards aluminum, the wires of this alloy have a double tensile strength. Its electrical conductivity is 15% lower(53% instead of 61%)and the weight is the same.
By making use of these characteristics, in many cases an alloy conductor can replace the
Aluminum Conductors Steel reinforced with a similar installation cost.
The Aluminum Alloy Steel Reinforced conductors have a much higher strength and its usage is ideal on long spans or under very severe mechanical conditions.
Main applications
Low, medium, high and very high voltages lines.
