Aluminium Alloy Conductor
AAAC stranded bare conductor for longer spans without a steel core
Product Overview
Aluminium alloy conductor trades a small amount of conductivity for substantially more tensile strength, and does it without a steel core. That last part is the reason it gets specified in coastal and chemically aggressive environments - there is no bimetallic interface for corrosion to attack at the joints.
Key Benefits
- Higher tensile strength than plain aluminium without a steel core
- No bimetallic interface to corrode in salty or aggressive air
- Longer spans achievable at acceptable sag than all aluminium
- Quoted alongside AAC and ACSR so the design can be compared before ordering
Problems It Solves
- Corrosion at the steel to aluminium interface in ACSR joints
- Spans that plain aluminium cannot hold at acceptable sag
- Choosing conductor on price per tonne rather than on mechanical need
Application Scenarios
- Coastal lines where bimetallic corrosion is a concern
- Spans longer than plain aluminium can hold at acceptable sag
- Chemically aggressive industrial environments
- Reconductoring to increase span capability
Who It Is For
- Distribution utilities on coastal networks
- Line design engineers comparing conductor options
- Construction contractors on longer span work
- EPC companies delivering line projects
Technical Features
- Stranded aluminium alloy construction
- Higher strength to weight ratio than AAC
- No steel reinforcing core
- Bare overhead conductor supplied on drums

Compared With Other Options
| AAC | Better conductivity per unit area, less strength. Fine on short spans, limiting on long ones. |
|---|---|
| ACSR | More strength again, but with a steel core and the bimetallic interface that comes with it. |
| Insulated bundled cable | Solves clearance and contact problems at a higher cost per metre and more weight to string. |
Use Guide
- Compare AAC AAAC and ACSR against your actual span and tension before selecting
- Match terminations to the conductor construction
- Plan drum lengths against the run schedule
- Protect drums from mechanical damage in storage and transport

Why is AAAC preferred on coastal lines
It avoids the steel to aluminium interface entirely, which removes the galvanic corrosion path that salt-laden air exploits at joints.
Is the conductivity penalty significant
It is a trade against a substantial strength gain. Whether it matters depends on whether your design is limited by current or by span.
Can you quote all three constructions
Yes - send the span and current requirements and the three are priced side by side.
