Aluminum-Alloy Reinforcement
Aluminum and aluminum alloy strands combine conductivity with improved mechanical strength.
ACAR – Aluminum Conductor Alloy Reinforced
Aluminum conductor with alloy reinforcement for high capacity and balanced mechanical performance.
ACAR uses aluminum and aluminum alloy strands to provide a practical balance of conductivity, strength-to-weight ratio and corrosion performance for overhead line projects.
Product Overview
ACAR conductors combine aluminum strands and aluminum alloy reinforcing strands in a concentric-lay construction. They are selected when a project needs strong electrical performance with improved strength-to-weight balance compared with conventional all-aluminum or steel-reinforced alternatives.
Applications
- overhead transmission and distribution routes
- line upgrades requiring improved capacity and weight balance
- routes where corrosion performance is part of conductor selection
- projects comparing AAC, AAAC, ACSR and ACAR alternatives
Construction
Concentric-lay construction using aluminum and aluminum alloy strands. The proportion of conductive aluminum and alloy reinforcement should be reviewed against the required standard, rated strength, resistance and line design.
Standards
- ASTM B524
- IEC 61089 or project-specific conductor standard where required
Main Features
Capacity and Strength Balance
Useful where the line design needs better ampacity than ACSR at comparable weight, subject to project calculation.
Overhead Upgrade Option
For ACAR - Aluminum Conductor Alloy Reinforced, ACAR can be reviewed for transmission, distribution and reconductoring routes where strength-to-weight balance matters.
Comparison Table
| Product / Route | Main Use | Selection Guidance |
| ACAR | Capacity and strength balance | Line upgrades and routes needing balanced electrical/mechanical performance. |
| ACSR | Maximum reinforced strength | Long spans and heavy mechanical loading. |
| AAAC | Alloy conductor simplicity | Corrosion-sensitive routes with alloy conductor preference. |
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.
