AA8176 Series Aluminum Alloy Conductor

AA8176 Series Aluminum Alloy Conductor

8000 series aluminum alloys have creep rates very similar to copper building wire, resulting in similar performance. 8000 has a higher strength-to-weight ratio than an equal ampacity copper wire. Since it is lighter, the pulling tension is lower. Lower pulling tension may decrease the chances of damaging the insulated wire in doing so. There is a wide range of strengths available from dead soft to mild steel,permitting a wide range of processing from wire drawing by rolling process to provide excellent ductility.

Construction

8000 Series Aluminum Alloy conductors use specific alloying elements (iron, silicon, copper, rare earths) for improved strength, reduced creep (deformation) compared to older aluminum, mimicking copper's performance for reliable terminations in cables like SER (Service Entrance, Round) or MC (Metal Clad), featuring compact stranding, XLPE insulation, and often a concentric neutral, designed for safer power delivery in various residential/commercial uses.
