ACSR/AW conductors consist of aluminum 1350 strands, woven in one or more layers around a central steel core coated with aluminum (AW) and having a circular cross-section.
The aluminum-coated steel core (AW) may consist of one or multiple strands — typically 7, 19, or 37 wires.
These conductors are manufactured in accordance with the requirements of ASTM B549, ASTM B502, and ASTM B230 standards.
Features
The steel core, which includes a thin layer of aluminum coating (approximately 10% of the nominal wire radius) surrounding the steel wire, forms ACSR/AW conductors. These conductors combine the lightweight and good electrical conductivity of aluminum with the high tensile strength of steel.
ACSR/AW conductors are mainly designed in the following strand configurations:
6/1, 7/1, 12/7, 36/1, 24/7, 26/7, 30/7, 30/19, 54/7, and 54/19.
Applications
Aluminum conductors steel reinforced with aluminum-coated steel cores (ACSR/AW) are used in transmission and distribution lines, particularly in areas where high corrosion resistance and high-temperature performance are required.
They are commonly used in polluted environments, coastal regions, and industrial areas where atmospheric or chemical corrosion may affect the conductors.
