ACAR (Aluminium Conductor Alloy Reinforced) is a concentric-lay-stranded conductor made from aluminum 1350 wires and a core of high-strength aluminum alloy wires. It combines the excellent electrical conductivity of aluminum with the superior mechanical properties of aluminum alloy. Due to its enhanced strength-to-weight ratio, ACAR conductors are widely used in overhead transmission and distribution lines where both electrical performance and mechanical strength are critical.
ACAR is especially suitable for long-span installations, high voltage lines, and environments with strong mechanical stress or wind load, such as coastal, mountainous, and high-altitude regions.
StructureACAR conductors are constructed as follows:
Conductor Type: Concentric-lay-stranded
Outer Layers: Hard-drawn aluminum 1350-H19 wires (high conductivity)
Core: High-strength aluminum alloy wires (typically 6201-T81)
Stranding Configuration: The number of aluminum and alloy strands can vary (e.g., 6 Al + 1 Alloy, 26 Al + 7 Alloy), depending on design requirements.
This combination results in a conductor that offers:
High conductivity (due to outer aluminum layers)
High tensile strength (thanks to the alloy core)
Uniform thermal expansion (all components are aluminum-based)
ACAR conductors are manufactured in accordance with the following international standards:
ASTM B524 - Standard Specification for Concentric-Lay-Stranded Aluminum Conductors, Aluminum-Alloy Reinforced (ACAR)
IEC 61089 - Round Wire Concentric Lay Overhead Electrical Conductors
BS EN 50182 - Conductors for overhead lines - Round wire concentric lay stranded conductors
DIN 48201-6 - Overhead power lines - ACAR conductors
Customized constructions can also be produced to meet national or project-specific requirements.
High Strength-to-Weight Ratio: Ideal for long-span applications and areas with high mechanical tension.
Corrosion Resistance: All-aluminum construction makes it suitable for coastal and humid environments.
Thermal Stability: Excellent thermal expansion characteristics ensure dimensional stability in variable temperatures.
High Conductivity: The 1350-H19 aluminum strands provide low resistance and efficient power transmission.
Reduced Sag: Compared to all-aluminum or ACSR, ACAR shows improved sag characteristics under high tension.
Magnetically Neutral: Unlike ACSR, there is no steel, so no inductive heating or eddy current losses.
ACAR is used in a wide range of overhead power transmission and distribution systems, including:
Long-span high voltage transmission lines
Distribution lines where high mechanical strength is needed
Compared to ACSR, ACAR provides more uniform conductivity, corrosion resistance, and reduced magnetic losses, making it an efficient and durable choice in modern power grids.
River crossings, mountainous terrains, and wind-prone areas
Areas requiring lightweight conductors with greater sag resistance
