Bare AAC Conductor for Power Transmission Project

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

Bare AAC Conductor for Power Transmission Project

 

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


CONSTRUCTIONM:

ALUMINUM WIRES ARE CONCENTRICALLY STRANDED

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 


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