Features of enameled cca wire 　　 1. DC resistivity: The DC resistivity of aluminum enameled wire is about 1.5 times that of pure copper wire; when the resistance value is the same, the weight of aluminum enameled wire is about 1/3 of that of pure copper wire 　　2. Solderability: The soldering tin of aluminum enameled wire joints requires special flux or aluminum solder wire 　　3. Light weight:...
