Frequently Asked Questions (FAQ)
Q:
What is an Aluminum Alloy Conductor (AAAC)?
AAAC (Aluminum Alloy Conductor) is a concentric-lay-stranded conductor made from high-strength Aluminum-Magnesium-Silicon alloy (usually 6201-T81). It is designed to provide a better strength-to-weight ratio and improved electrical properties compared to standard AAC conductors.
Q:
What does the "Z" twist direction mean for AAAC?
The "Z" twist direction indicates that the outermost layer of the conductor is stranded in a right-hand lay (clockwise direction). This is the industry standard configuration for most overhead transmission and distribution lines.
Q:
What are the benefits of using AAAC over ACSR?
AAAC offers superior corrosion resistance compared to ACSR (Aluminum Conductor Steel Reinforced) because it contains no steel core that could rust. It also exhibits lower power losses, lighter weight, and easier handling during installation.
Q:
How are the code names (like BOX, ALMOND, OAK) determined?
These code names are standard industry designations used to simplify ordering and specification. They represent specific cross-sectional areas, stranding configurations, and physical dimensions of the conductor.
Q:
At what temperature is the maximum resistance of AAAC measured?
The maximum DC electrical resistance values for AAAC conductors are standardized and measured at a reference temperature of 20°C (68°F), in accordance with international electrical standards.
