<p>The cable, made from an assembly of wires, each with an aluminum core covered with a layer of electrolytically-deposited copper, has an intermediate layer of metal selected from nickel, niobium, tantalum and vanadium between the core and copper layers. Where nickel is used it is deposited electrolytically, while niobium, tantalum and vanadium are applied in leaf form. The intermediate metal layer can be applied to aluminum bar which is continuously welded, cold stretched and drawn.</p> |
