AAC – All Aluminum Conductor

AAC – All Aluminum Conductor

All-aluminum bare overhead conductor for standard transmission and distribution routes.

AAC is used where conductivity, light weight and standard-based conductor sizing are the key selection factors for overhead line design.

  • Key Technical Points:
  • Concentric-lay stranded aluminum conductor for bare overhead line routes.
  • Commonly reviewed for short to medium spans and lower mechanical loading.
  • Selection based on conductor size, stranding, DC resistance and rated strength
  • Conductor area, stranding, DC resistance and rated strength should follow the selected standard table.
  • Product Overview

    AAC conductors are bare overhead conductors made from concentrically stranded aluminum wires. They are typically selected for transmission, distribution and feeder routes where electrical conductivity, conductor weight and standard-based sizing are more important than very high tensile strength.

    Applications

    • overhead transmission and distribution lines
    • utility feeder and distribution routes
    • substation or busbar connections
    • replacement projects requiring standard-based bare conductor selection

    Construction

    Concentric-lay stranded aluminum conductor without insulation, sheath or armour. Final conductor size, stranding, DC resistance, weight and rated strength should be checked against the selected project standard.

    Standards

    • IEC 61089
    • ASTM B231
    • BS 215
    • DIN 48201
    • GB/T 1179
    • AS 1531 where specified

    Main Features

    All-Aluminum Construction

    Stranded aluminum conductors provide good conductivity with lower conductor weight for overhead line routes.

    Standard Conductor Sizing

    Conductor area, stranding, DC resistance and rated strength can be checked against IEC, ASTM, BS, DIN or GB tables.

    Practical Distribution Use

    For AAC - All Aluminum Conductor, a suitable option for short to medium spans where very high tensile strength is not the main selection factor.

    Comparison Table

    Product / Route Main Use Selection Guidance
    AAC Conductivity and low weight Short to medium spans with moderate mechanical loading.
    AAAC Higher strength and corrosion resistance Routes needing better strength-to-weight performance.
    ACSR High tensile strength Longer spans and higher mechanical loading.

    Product Selection Guide

    Standard & Size Route

    Confirm whether the project uses IEC, ASTM, BS, DIN, GB, AS or NFC conductor tables before selecting size.

    Electrical Requirement

    Compare nominal area, DC resistance and current requirement against the line design and utility specification.

    Mechanical Loading

    Check rated strength, span length, sag requirement and wind/ice conditions before confirming conductor family.

    Alternative Conductors

    For higher tension or corrosion performance, compare AAC, AAAC, ACSR, ACAR, AACSR or ACSR/AW as applicable.
