Application Summary AI generated

This standard specifies the technical requirements, test methods, and acceptance criteria for thermal-resistant aluminium alloy wires used in overhead line conductors. It is applied in the power transmission industry for manufacturing conductors that operate at continuous temperatures up to 150°C, enabling higher current-carrying capacity and reduced sag in high-voltage transmission lines. The standard ensures consistent performance and reliability in applications such as grid upgrades, urban power distribution, and long-distance overhead lines.
