AAC All Aluminum Conductor
AAC is composed entirely out of 1350-H19 aluminum wires.
AAC has a good corrosion resistance due to being composed out of aluminum wires only, it has low price, minimum conductivity of 61.2% IACS low breaking strength and high creep values. AAC has the highest conductivity per weight among all bare overhead conductors.
AAC is recommended for use where high current transfer is required in short spans making it idle for use in urban areas.
AAC bare conductors meet or exceed the following ASTM specifications:
B-230 Aluminum Wire, 1250-H19 for Electrical Purposes
B-231 Aluminum Conductors, Concentric-Lay-Stranded
B-400 Compact Round Concentric-Lay-Stranded Aluminum 1350 Conductors
