    Note: The outermost layer is twisted to the right (Z).
    Frequently Asked Questions (FAQ)
    What does the twist direction "Z" mean for the outermost layer?
    The "Z" twist refers to a right-hand lay direction for the outermost strands of the ACSR conductor. This standard configuration ensures proper mechanical stability and performance during installation and operation.
    How is the maximum resistance of ACSR conductors measured?
    The maximum DC resistance values specified in the table are calculated and measured at a standard reference temperature of 20℃, expressed in Ohms per kilometer (Ω/km).
    What is the purpose of the galvanized steel core in ACSR?
    The galvanized steel core provides the primary mechanical strength and load-bearing capacity (Nominal Breaking Load) for the conductor, while the outer aluminum strands carry the electrical current.
    What factors determine the Modulus of Elasticity in ACSR?
    The Modulus of Elasticity (ranging from 60,000 to 110,000 N/mm² in the table) is determined by the ratio of the cross-sectional area of the aluminum strands to that of the galvanized steel core.
    How does the current-carrying capacity scale with the conductor size?
    As the total sectional area of the aluminum increases from 15.3 mm² to 1045.6 mm², the current-carrying capacity scales up from 105 A to 1580 A, allowing for higher power transmission capacity.
