1. Low resistivity: the resistivity of aluminum core cable is about 1.68 times higher than that of copper core cable.
2. Good ductility: the ductility of copper alloy is 20*40%, the ductility of electrical copper is more than 30%, while the ductility of aluminum alloy i......

This can be explained not only from the theory of electrical geometry, but also from the operating conditions. The UHV overhead transmission lines of the former Soviet Union had trips due to lightning strikes several times during their operation.
