Stranded 1350 aluminum conductors shown in this section of data are classified as follows:
Class AA For bare conductors usually used in overhead lines.
Class A For conductors to be covered with weather-resistant materials and for bare conductors where greater flexibility is required.
Compact strand conductor for use in bare overhead applications or for use with weather-resistant coverings or insulations is also available.
Classes refer to stranding and are an indication of relative conductor flexibility, AA being the least flexible, C the most flexible.

Construction
Aluminum alloy 1350-H19 wires, concentrically stranded.

Specifications
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

AAC is used mainly in urban areas where the spacing is short and the supports are closer together. The advantage of AAC conductors is that they have a high degree of corrosion resistance; for this reason they are used extensively in coastal areas. AAC Conductors were developed as a consequence of the galvanic corrosion that ACSR conductors are susceptible to.
