  • Bare Aluminum

    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.

    Specifications
    AAC bare conductors meet or exceed the following ASTM specifications :

    B-230 Aluminum Wire, 1350-H19 for Electrical Purposes
    B-231 Aluminum Conductors, Concentric-Lay-Stranded
    B-400 Compact Round Concentric-Lay-Stranded Aluminum 1350 Conductors

    Notes

    • Resistance is calculated using ASTM standard increments of stranding and metal conductivity of 52.5% IACS, AC resistance at 60Hz
    • Current ratings are based on 75 ºC conductor temperature, 25 ºC ambient, 2ft/s wind, 96/watts/sq.ft sun, .05 coefficients of emissivity and absorption.
