    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 does AAC stand for in overhead conductors?
    AAC stands for Aluminum Stranded Conductor (or All Aluminum Conductor). It is primarily used for overhead electricity distribution lines with relatively short spans due to its high conductivity and corrosion resistance.
    What is the standard twisting direction for the outermost layer of AAC?
    According to the technical specifications, the outermost layer of the AAC conductor is twisted to the right, which is designated as the Z-lay direction.
    Which international standard applies to the structure parameters of these conductors?
    While the elastic and expansion coefficients in this table are specifically applicable to Germany, calculations for other conductor structural parameters should refer to the IEC 61597 international standard.
    Under what conditions are the current-carrying capacities in the table calculated?
    The current-carrying capacity (flow rate) is calculated based on a frequency of 60Hz, a wind speed of 0.6m/s, sunlight exposure in Germany, an ambient temperature of 35°C, and a maximum conductor temperature of 80°C.
    How do special laying conditions affect the flow rate values?
    For special laying conditions where there is no natural or forced convection, the current-carrying capacity (flow rate) values should be reduced by less than 30% to prevent overheating.
    What is the correlation between the code name and sectional area of AAC conductors?
    The code name prefix (e.g., 16-AL1, 24-AL1, 400-AL1) represents the approximate nominal sectional area in mm² (e.g., 15.9 mm², 24.2 mm², and 400.1 mm² respectively), indicating the physical size and capacity of the aluminum conductor.
