Aluminum Cables

Aluminum conductors are used extensively in insulated cables, most notably solid sector power cables, which have three solid sector aluminum conductors and aluminum armor. The armor, which takes the form of flattened wire with the individual wires laid edge to edge round the cores, acts as neutral and earth return and ob­viates the fourth conductor often incor­porated with the phase conductors. Aluminum cables also have extensive application in service entrance cable and overhead service drop.
