    Frequently Asked Questions

    What are the main components of these conductors?

    These conductors consist of a central high-strength steel core wrapped in outer layers of aluminum alloy wires. The steel core provides tensile strength, while the aluminum alloy provides electrical conductivity.

    Why is the D.C. resistance measured specifically at 20°C?

    20°C is the industry standard reference temperature for electrical calculations. Measuring resistance at this temperature ensures consistent baseline comparisons for line efficiency and power loss calculations.

    How does the steel core impact the conductor's rated strength?

    A larger steel core sectional area directly increases the rated strength (tensile capacity) of the conductor, enabling longer spans between transmission towers but also increasing the linear mass.

    What is the significance of the stranding number (No.)?

    The stranding number indicates how many individual wires make up the aluminum alloy or steel sections. More wires generally offer better conductor flexibility and easier handling during installation.

    Where are these overhead conductors typically applied?

    They are widely used in overhead electrical transmission and distribution lines, particularly where high mechanical tension is required to span across rivers, valleys, or long distances.
