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 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 75oC conductor temperature, 25oC ambient, 2ft/s wind, 96/watts/sq.ft sun, .05 coefficients of emissivity and absorption.
