When electricity has to travel across long distances, the conductor is doing much more than carrying current. It also has to deal with mechanical tension, wind, temperature changes, installation conditions, and the physical demands of the transmission route. That is why Aluminum Conductors used in overhead power transmission are available in several different constructions rather...
The overhead transmission conductor market has historically been dominated by ACSR, Aluminum Conductor Steel Reinforced, for the simple reason that the steel core provides the tensile strength needed to span long distances between towers without excessive sag, while the aluminum strands carry the current. AAAC, All Aluminum Alloy Conductor, uses aluminum alloy strands throughout rather...
