Alloy Conductor with Steel Core
Aluminum alloy strands and steel reinforcement support higher mechanical loading in bare overhead routes.
AACSR – Aluminum Alloy Conductor Steel Reinforced
Aluminum alloy conductor with steel reinforcement for high-strength overhead line applications.
AACSR combines aluminum alloy conductor strands with a steel core, supporting higher mechanical strength while retaining alloy conductor performance for demanding overhead routes.
Product Overview
AACSR conductors use aluminum alloy strands around a steel reinforcing core. This construction is considered when line routes require stronger mechanical performance than ordinary all-alloy conductors and where project standards call for alloy conductor steel reinforced designs.
Applications
- high-strength overhead transmission routes
- long span or heavy mechanical loading sections
- line routes requiring aluminum alloy conductor performance with reinforcement
- utility projects comparing AAAC, ACSR and AACSR options
Construction
Concentric-lay aluminum alloy wires stranded around a steel core. Final alloy, core configuration, rated strength, resistance and conductor dimensions should follow the selected standard.
Standards
- IEC 61089
- ASTM B711
- GB/T 1179 where specified
Main Features
Strength-Focused Selection
Suitable where tensile strength and span performance are more important than minimum conductor weight.
Project Standard Review
For AACSR - Aluminum Alloy Conductor Steel Reinforced, alloy stranding, steel core, rated strength and resistance should follow the required IEC, ASTM or GB route.
Comparison Table
| Product / Route | Main Use | Selection Guidance |
| AACSR | Alloy plus steel reinforcement | High-strength routes requiring alloy conductor performance. |
| AAAC | Alloy conductor without steel | Corrosion-sensitive routes with lighter mechanical demand. |
| ACSR | Conventional aluminum-steel conductor | Broad utility use with standard steel reinforcement. |
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.
