Aluminum Conductor Aluminum Clad Steel Reinforced (ACSR/AW) | High-Performance Hybrid Overhead Conductor

Key Advantages of ACSR/AW Conductor

• Superior Corrosion Resistance — Aluminum-clad steel core provides 5–10× better protection than galvanized steel in standard ACSR. Ideal for coastal, marine, salt-fog, and industrially polluted environments with minimal maintenance requirements.
• High Mechanical Strength & Fatigue Resistance — Offers excellent tensile strength and fatigue performance for long spans, heavy ice/wind loads, and river crossings.
• Improved Conductivity & Lower Losses — Higher effective aluminum content reduces DC resistance and electrical losses compared to traditional ACSR, enabling higher ampacity (up to ~20% more current in equivalent designs).
• Optimized Low Sag Performance — Lower thermal expansion and creep characteristics allow longer spans and reduced tower heights, lowering overall project costs.
• Extended Service Life — Proven 40+ year design life in extra-high-voltage (EHV) and ultra-high-voltage (UHV) lines, with identical geometry to ACSR for drop-in replacement and full hardware compatibility.
• Reduced Total Cost of Ownership — Lower maintenance, fewer replacements, and higher energy efficiency deliver superior long-term ROI.

Main Applications

ACSR/AW conductors are widely used in:

• High-voltage and extra-high-voltage overhead transmission lines (up to UHV)
• Long-span river crossings and heavy ice/wind load zones
• Coastal, marine, and high-corrosion environments
• Capacity upgrades of existing lines without requiring tower reinforcement
• Messenger support and distribution lines in aggressive climates

These characteristics make ACSR/AW particularly suitable for major transmission and grid modernization projects in the Saudi Kingdom and GCC region, including coastal industrial areas (e.g., Jubail, Yanbu, Red Sea developments) and long-span lines supporting Vision 2030 infrastructure expansion.

Construction & Manufacturing Standards

ACSR/AW consists of concentric-lay stranded round aluminum 1350-H19 wires surrounding one or more round aluminum-clad steel (AW) core wires. This hybrid design balances electrical conductivity from the aluminum with mechanical reinforcement and corrosion protection from the clad steel core.

Produced in full compliance with international standards:

• ASTM B549
• IEC 61089
• Additional references: BS 215, AS 3607, GB/T 1179 (custom configurations available)

Representative Technical Specifications (ASTM B549)

A complete range of sizes and configurations is available to meet specific project requirements. Common sizes follow similar geometry to standard ACSR for easy substitution.
