Aluminum-Clad Steel Strand
Steel strength with an aluminum cladding supports corrosion-resistant mechanical or grounding applications.
ACS – Aluminum Clad Steel Strand
Aluminum-clad steel strand for high-strength overhead support, messenger and reinforcement applications.
ACS provides steel-core mechanical strength with an aluminum cladding surface, making it suitable for selected overhead line, support and grounding-related applications.
Product Overview
ACS is an aluminum-clad steel strand product used where high mechanical strength is required together with an aluminum-clad surface. It can be used in overhead line support, shield wire, ground wire or conductor-core applications depending on the project specification.
Applications
- overhead ground wire and shield wire routes
- messenger strand and support applications
- reinforcement core applications for selected conductors
- utility and infrastructure projects requiring high-strength metallic strand
Construction
Steel wire or strand with aluminum cladding. Final grade, class, wire diameter, stranding and rated breaking strength should be confirmed against the required strand specification.
Standards
- ASTM B416
- project-specific utility strand requirements
Main Features
Messenger and Support Duty
Commonly reviewed for support, grounding, guying or reinforcement routes where mechanical strength is central.
Coating and Strength Control
For ACS - Aluminum Clad Steel Strand, wire diameter, coating thickness, breaking strength and lay configuration should match the selected standard.

| Product / Route | Main Use | Selection Guidance |
| ACS | Aluminum-clad steel surface | Support, shield and grounding-related overhead applications. |
| GSW | Galvanized steel protection | Guy wire and support strand where galvanizing is specified. |
| CCS | Copper-clad steel conductivity | Grounding or signal-related routes requiring copper surface conductivity. |
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.
