    Technical Notes:
    1. The outermost layer is twisted to the right (Z).
    2. The elastic coefficients and expansion coefficients listed in this table are applicable to Germany. The calculation of other conductor structure parameters shall refer to IEC61597.
    3. The flow rate values listed in this table are applicable under the conditions of a frequency of 60HZ, a wind speed of 0.6m/S, sunlight exposure in Germany, an ambient temperature of 35℃, and a conductor temperature of 80℃. In case of special laying conditions, the flow rate values should be reduced if there is no convection Less than 30%.
    Frequently Asked Questions (FAQ)
    What is AAC (Aluminum Stranded Conductor) used for?
    AAC (All Aluminum Conductor) is primarily used for overhead electricity distribution lines. Because it is made entirely of refined aluminum, it offers excellent electrical conductivity, high corrosion resistance, and is highly cost-effective for short to medium span installations.
    What does "outermost layer twisted to the right (Z)" mean?
    This refers to the lay direction of the outermost wire strands. A right-hand lay (Z-lay) is the standard helical direction used during stranding to ensure structural integrity, uniform mechanical performance, and compatibility with standard line fittings and hardware.
    Which standard calculations apply to these AAC conductors?
    While the elastic and expansion coefficients in this specification table are specific to German standards, calculations for other conductor structural parameters and variations should refer to the international standard IEC 61597.
    How do environmental conditions affect the current-carrying capacity of AAC?
    The rated current capacities are calculated under specific nominal conditions (60Hz frequency, 0.6m/s wind speed, German sunlight exposure, 35°C ambient, and 80°C conductor temperature). If installed in areas without natural convection or under special laying conditions, the current-carrying capacity should be derated by up to 30%.
    What are the main advantages of AAC over ACSR conductors?
    AAC is lighter and has a higher conductivity-to-weight ratio than ACSR (Aluminum Conductor Steel Reinforced) because it contains no steel core. This makes AAC highly resistant to galvanic corrosion, particularly in coastal or industrial environments, though it has lower tensile strength and is best suited for shorter spans.
