Frequently Asked Questions (FAQ)
What does AAAC stand for and what are its main applications?
AAAC stands for Aluminum Alloy Conductor. It is widely used as bare overhead conductor for power transmission and distribution lines, particularly in coastal or industrial environments where high corrosion resistance is required.
What do the code names like "ASTER" represent in the specifications?
Code names (such as ASTER 22, ASTER 54.6, etc.) are standard industry designators used to identify specific conductor configurations, sectional areas, and physical properties of the AAAC cable.
Why is the outermost layer of the AAAC conductor twisted to the Left (S)?
The Left-hand lay (S-direction) for the outermost layer is a standard manufacturing specification. It ensures mechanical stability, prevents unraveling during installation, and matches standard hardware and accessories used in overhead line construction.
How does the sectional area of AAAC affect its electrical resistance?
There is an inverse relationship: as the sectional area increases, the electrical resistance decreases. For example, ASTER 22 (22.0 mm²) has a maximum resistance of 1.4989 Ω/km, whereas ASTER 1600 (1595.9 mm²) has a resistance of only 0.0210 Ω/km.
What are the key advantages of using AAAC over ACSR?
AAAC offers excellent corrosion resistance (especially in coastal or industrial areas), lighter weight, lower electrical losses, and a higher strength-to-weight ratio compared to ACSR (Aluminum Conductor Steel Reinforced) without needing a steel core.
