The structure and makeup of the conductors distinguish ACSR (Aluminum Conductor Steel Reinforced) from ACSR/AW (Aluminum Conductor Steel Reinforced/Aluminum-Clad Steel Reinforced):
1. Construction: A central steel core is encircled by several layers of aluminum wires in both ACSR and ACSR/AW conductors. On the other hand, the steel core of ACSR/AW conductors is encircled by an extra layer of steel wires coated in aluminum.
2. Aluminum-Clad Steel (ACS) Layer: The outer layer of ACSR/AW conductors is made up of steel wires coated in aluminum. These cables are made of an aluminum layer that is adhered to a steel core. The steel wires covered in aluminum give the conductor more strength and mechanical support.
3. Conductivity: Good electrical conductivity is provided by the aluminum wires used throughout the fabrication of ACSR conductors. The outer layer steel wires covered in aluminum in ACSR/AW conductors do not make a substantial contribution to the total electrical conductivity. Consequently, the electrical conductivity of ACSR/AW conductors is somewhat lower than that of ACSR conductors.
4. Mechanical Strength: The mechanical strength and durability of ACSR/AW conductors are improved by the steel wires that are coated in aluminum. Because ACSR/AW conductors have an extra layer of aluminum-clad steel wires, they are more resistant to stretching and drooping, which makes them appropriate for overhead line applications that involve higher mechanical loads.
5. Corrosion Resistance: Due to the inherent corrosion resistance of steel and aluminum components, both ACSR and ACSR/AW conductors show good corrosion resistance.
Locations with higher mechanical loads, such as coastal regions or locations vulnerable to severe winds or ice loading, are the main applications for ACSR/AW conductors. While retaining the advantages of aluminum conductors, such as their lightweight design and superior electrical conductivity, the aluminum-clad steel layer of ACSR/AW conductors increases mechanical strength.
To choose the right conductor type for a given project, it’s crucial to speak with electrical engineers or refer to industry standards. These factors include project needs, environmental factors, and mechanical stress considerations.
