The Aluminium Alloy Conductor Steel Reinforced (AACSR) is meticulously crafted from either 6201 or 6101 aluminium alloys, enriched with aluminium-silicon-magnesium (Al-Si-Mg) constituents. These specialized alloy wires are precisely stranded around a central steel core, which can be galvanized, galfan-coated, or aluminium-cladded. The strategic fusion of aluminium alloy wires with a steel core yields distinct advantages, underscoring the versatility and strength of AACSR conductors.

The Aluminium Alloy Conductor Steel Reinforced (AACSR) is meticulously crafted from either 6201 or 6101 aluminium alloys, enriched with aluminium-silicon-magnesium (Al-Si-Mg) constituents. These specialized alloy wires are precisely stranded around a central steel core, which can be galvanized, galfan-coated, or aluminium-cladded. The strategic fusion of aluminium alloy wires with a steel core yields distinct advantages, underscoring the versatility and strength of AACSR conductors.
One of the most notable attributes of AACSR conductors is their remarkable tensile strength. When juxtaposed with traditional ACSR conductors, the integration of aluminium alloy wires with a steel core engenders a notable enhancement, with tensile strength rising by approximately 35% to 60%. This heightened tensile strength equips AACSR conductors to withstand greater mechanical forces and environmental stresses.
However, it's important to note that this increase in tensile strength comes with a trade-off. The electrical resistance of AACSR conductors is comparatively higher than that of ACSR conductors due to the incorporation of aluminium alloy wires. Despite this, the unique combination of strength and electrical performance renders AACSR conductors particularly advantageous for specific scenarios.
One such scenario is when extended span lengths are a consideration. The commendable strength-to-weight ratio exhibited by AACSR conductors positions them as a compelling alternative to traditional ACSR conductors, especially in situations where longer span lengths are required. This versatility ensures that AACSR conductors are well-suited for various applications, providing an optimal balance between strength, durability, and electrical conductivity in transmission and distribution systems.
Advantages of AACSR conductors:
- Elevated mechanical strength and reduced sag in comparison to ACSR conductors
- Exceptional strength-to-weight ratio
- Appropriate for transmission lines with extended span length
