Frequently Asked Questions (FAQ)
What is Aluminum Stranded Conductor (AAC)?
Aluminum Stranded Conductor (AAC), also known as aluminum stranded wire, is refined from EC grade aluminum with a minimum purity of 99.7%. It is primarily used in urban overhead transmission lines with short spans and high conductivity requirements.
What do the code names like "Leo", "Libra", and "Mars" represent?
These code names are standard industry designations (often based on constellations or celestial bodies) used to simplify the ordering and specification process. Each code name corresponds to a specific sectional area, stranding configuration, and physical dimensions.
Why is the outermost layer of the AAC conductor twisted to the right (Z-lay)?
The right-hand lay (Z-lay) is the standard direction of rotation for the outer layer of stranded conductors. This configuration ensures structural stability during installation and tensioning, preventing birdcaging or unwinding under mechanical stress.
What is the relationship between the number of wires and the conductor's flexibility?
Generally, conductors with a higher number of stranded wires (such as 37 or 61 wires) offer greater flexibility and ease of handling compared to conductors with fewer strands (like 7 wires) for a similar overall cross-sectional area.
How does temperature affect the maximum resistance of AAC?
The electrical resistance values provided in the technical table are calculated at a standard reference temperature of 20℃. As the operating temperature increases, the electrical resistance of the aluminum material will also increase, which affects overall line efficiency.
