Aluminum-Clad Steel Core
The aluminum-clad steel reinforcement improves corrosion resistance compared with conventional galvanized steel core routes.
ACSR/AW – Aluminum Conductor Aluminum Clad Steel Reinforced
Aluminum conductor with aluminum-clad steel reinforcement for overhead line routes.
ACSR/AW keeps the reinforced conductor concept of ACSR while using aluminum-clad steel core wires to improve compatibility and corrosion performance in selected environments.
Product Overview
ACSR/AW conductors are aluminum conductor steel reinforced products using aluminum-clad steel core wires. They are considered when a project needs reinforced conductor strength while reviewing corrosion performance, core material compatibility and standard-specific conductor values.
Applications
- overhead transmission and distribution line routes
- corrosion-sensitive or special utility specification projects
- reinforced conductor replacements where aluminum-clad steel core is required
- line sections comparing ACSR, ACSR/AW and AAAC alternatives
Construction
Concentric-lay aluminum strands around aluminum-clad steel core wires. Aluminum-clad steel grade, stranding, rated strength, resistance and dimensions should be confirmed according to the project standard.
Standards
- ASTM B549
- IEC 61089 or project-specific conductor standard where required
Main Features
High-Tension Overhead Use
Designed for overhead lines requiring higher mechanical strength, longer spans and controlled conductor sag.
Transmission-Line Review
For ACSR/AW - Aluminum Conductor Aluminum Clad Steel Reinforced, aluminum area, steel core construction, rated strength and resistance should be reviewed against the selected standard.
Comparison Table
| Product / Route | Main Use | Selection Guidance |
| ACSR/AW | Aluminum-clad steel core | Reinforced line routes with corrosion or core material requirements. |
| ACSR | Galvanized steel core | Standard reinforced overhead conductor route. |
| ACAR | All-aluminum family reinforcement | Capacity and corrosion balance without steel core. |
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.
