(56) Applications 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.
