AACSR-Aluminum Alloy Conductor Steel Reinforced

Application

Used as bare overhead transmission conductor and as primary and secondary distribution conductor and messenger support. ACSR conductors where the aluminum wires are replaced with the high strength aluminum alloy material. These super high strength conductors are used in river crossings or for long span applications where the traditional ACSR conductor will not work.

DESCRIPTION

AACSR is a concentrically stranded conductor composed of one or more layers of Aluminium -Magnesium -Silicon Alloy wire stranded around a high strength coated steel core. The core can be of either single wire or stranded multi wire. Additional corrosion protection is available through the application of grease to the core or infusion of the complete cable with grease. It is applied for large span overhead transmission and distribution lines than ACSR.

FAQ

What Is AACSR Conductor ?

AACSR is a type of bare overhead conductor made with 6201-T81 aluminum alloy strands wrapped around a high-strength galvanized steel core. The aluminum alloy carries the electric current, while the steel core provides extra tensile strength to support the line over long spans.

What is the Key Advantages of AACSR Conductor ?

Higher tensile strength for longer spans and heavy ice/wind loads
Better creep resistance and lower sag, which means fewer support structures
Good conductivity from the 6201 aluminum alloy
Higher operating temperature — continuous use up to 90°C, with heat-resistant versions reaching 150°C or more
Strong resistance to corrosion when properly coated or greased
Lightweight yet durable design that helps reduce overall line costs

What is the application of AACSR conductor ?

High-voltage transmission lines with long spans
Areas prone to heavy ice, strong winds, or snow
Coastal or industrial zones where corrosion resistance matters
Upgrading existing lines to handle higher loads with less sag
Ground wires and communication lines in overhead systems
