AAAC all aluminium alloy conductor stranded wire

AAAC All Aluminium Alloy Conductor

AAAC conductor uses aluminium-alloy wires throughout its concentric construction, with no separate steel core. Available alloy systems, including catalogue 6201 and 1120 designs, provide different balances of strength, conductivity and mass. The selected alloy, standard and conductor code must be stated because similarly sized AAAC constructions are not necessarily equivalent.

Key Advantages

  • More mechanical capability than AAC: Alloy wires provide a different strength-conductivity balance.
  • No steel core: Strength is developed across the all-alloy section.
  • Useful for exposed routes: Low mass and alloy construction suit selected longer-span designs.

Product Overview

The defining feature of AAAC is a homogeneous aluminium-alloy cross-section. Unlike ACSR or AACSR, it does not divide current-carrying and reinforcing functions between aluminium layers and a steel core. The alloy grade and temper determine the wire properties used in the finished conductor design. 6201, 1120 and Almelec-related constructions should be treated as separate technical options. Procurement should follow the specified standard and approved table, including strand count, wire diameter, mass, resistance and rated strength, rather than selecting by nominal area alone.

Key Features

  • All strands are aluminium alloy, eliminating a dissimilar-metal steel core from the conductor cross-section.
  • The alloy system gives greater tensile capability than AAC while retaining relatively low conductor mass.
  • Corrosion assessment is simplified where a ferrous core would be undesirable, but fittings and environmental exposure still need review.
  • Different alloy grades and standard tables produce different electrical and mechanical values and must be specified explicitly.

Product Applications

  • Overhead distribution requiring more mechanical strength than AAC
  • Longer spans and exposed terrain where an all-alloy conductor is suitable
  • Selected coastal or industrial routes after conductor and hardware compatibility review

Inquiry

From Production to Delivery

From raw material preparation to final shipment, every stage is carefully controlled to ensure consistent conductor quality, reliable performance, and safe delivery. Our production, inspection, packaging, and logistics processes are managed in accordance with applicable standards and project requirements.

Overhead conductor production and stranding process

Production

Alloy rod is drawn and heat-treated as required for the specified alloy and temper before the wires are concentrically stranded.

Cable and conductor quality inspection and testing

Inspection

Inspection verifies alloy-wire dimensions, surface, strand arrangement and the mechanical and construction values required by the chosen catalogue standard.

Overhead conductors packed on wooden drums for shipment

Packaging

AAAC is wound with controlled tension to protect the alloy-wire surface, with conductor code and alloy designation identified on the drum.

Wooden drums of overhead conductors loaded into shipping container

Shipping

Shipment records link each drum to its ordered length and applicable documentation; storage and unloading instructions should prevent drum movement or surface damage.

Frequently Asked Questions

Should an enquiry specify AAAC 6201, 1120 or only the conductor size?

Specify the alloy or governing standard as well as the size. The alloy grade and temper affect conductivity, rated strength and construction, so a nominal area alone is not enough to identify the required conductor.

AAAC is considered when the route needs more tensile capability or longer spans than an AAC design can provide, while retaining an all-aluminium-alloy construction without a steel core.

No. AAAC and ACSR distribute mechanical load differently and can have different diameter, mass, sag, strength and fitting requirements. A complete line-design comparison is required.

Provide span lengths, ruling span, wind and ice loads, operating temperature, clearance limits, pollution or corrosion conditions and the existing or proposed hardware system.

Yes. Compression dies, sleeves, dead-ends and installation procedures must be approved for the conductor alloy, diameter, strand construction and required mechanical rating.

Reference the applicable standard and edition, then state the required construction, dimensions, resistance, mechanical tests, documentation, sampling and any witnessed inspection requirements.
