    Frequently Asked Questions
    What is the difference between Nominal Area and Total Sectional Area?
    Nominal Area is a standardized commercial designation for the conductor size. The Total Sectional Area represents the actual calculated sum of the cross-sectional areas of the individual aluminum alloy and steel wires.
    Why do these conductors combine aluminum alloy and steel?
    The aluminum alloy layers provide high electrical conductivity and corrosion resistance, while the central steel core provides high tensile strength, enabling longer spans with less mechanical sag.
    How does wire stranding affect the conductor's performance?
    Stranding multiple wires together makes the overall conductor flexible for easier installation. The ratio of aluminum alloy to steel strands determines the balance between electrical resistance and mechanical strength.
    Why is Max D.C. Resistance specified at exactly 20℃?
    Conductor resistance changes with temperature. 20℃ is the standard reference temperature used globally to compare the electrical performance and efficiency of power cables.
    How does Rated Strength relate to the linear mass?
    Rated Strength (kN) indicates the maximum load the conductor can handle before breaking. A higher steel content increases both the rated strength and the linear mass (kg/km) of the conductor.
