Frequently Asked Questions (FAQ)
Q1.
What is an Aluminum Stranded Conductor (AAC)?
An Aluminum Stranded Conductor (AAC) is a refined aluminum conductor with a minimum purity of 99.7%. It is primarily used in overhead electrical transmission and distribution lines with relatively short spans where high conductivity and corrosion resistance are required.
Q2.
What does the "Z" twist direction mean for AAC conductors?
The "Z" twist indicates that the outermost layer of the stranded aluminum wires is wound in a right-hand lay (clockwise direction). This standard configuration ensures mechanical stability and consistent performance during installation and tensioning.
Q3.
How do I choose the correct AAC code name (e.g., Leo, Mars, Venus)?
Each code name corresponds to a specific sectional area, diameter, and electrical properties. For instance, "Leo" has a sectional area of 34.36 mm² for lighter loads, while "Venus" offers 673.73 mm² for high-capacity applications. Refer to the specifications table to match your current-carrying capacity and mechanical strength requirements.
Q4.
What are the main advantages of AAC conductors?
AAC conductors offer excellent electrical conductivity, superior corrosion resistance (especially in coastal or industrial environments), and a high strength-to-weight ratio. They are also cost-effective and easy to install compared to copper conductors.
Q5.
Can AAC conductors be used for long-span overhead lines?
AAC has lower mechanical strength compared to ACSR (Aluminum Conductor Steel Reinforced) or AAAC (All Aluminum Alloy Conductor). Therefore, it is ideal for short to medium spans in urban distribution networks rather than extra-long span transmission lines.
