    Frequently Asked Questions (FAQ)
    What is an Aluminum Stranded Conductor (AAC)?
    AAC (Aluminum Stranded Conductor) is a refined aluminum stranded conductor with a minimum purity of 99.7%. It is primarily used in overhead electricity transmission and distribution lines, particularly in urban areas where spacing is short and supports are close.
    What does the "Z" twist direction mean for AAC conductors?
    The "Z" twist denotes a right-hand lay direction for the outermost wire strands of the conductor. This specific standard configuration ensures mechanical consistency, structural stability, and compatibility during installation with standard tension clamps and fittings.
    What are the advantages of using AAC over other conductor types?
    AAC conductors offer excellent corrosion resistance because they are made entirely of aluminum. They also offer a high level of electrical conductivity and are highly cost-effective, making them ideal for coastal regions and urban distribution networks.
    How does the sectional area of AAC affect its electrical performance?
    A larger sectional area (measured in mm²) decreases the maximum electrical resistance at 20℃, allowing the conductor to carry higher electrical current loads with minimal energy loss.
    Which industry standards apply to these AAC conductors?
    AAC conductors are typically manufactured and tested to comply with major international specifications, including IEC 61089, ASTM B231, BS 215, and DIN 48201, ensuring reliable performance in global electrical grids.
