Where Southwire sits in the stack
Southwire's placements in this catalog cover 3 parts, from layer 7 (electrical: power distribution (grid to rack)) to layer 10 (materials & upstream inputs). None of them currently carries a sourced supply constraint tag. Across these parts it overlaps with other companies most often on the lines below.
What these parts are
- Refining and products — Smelters, refiners and product manufacturers that turn mined copper into wire, cable, sheet, strip and machined parts used across the data center.
- LV cable, wire, tray, raceway — Low-voltage power cable and wire, and the tray and raceway systems that route and support it between switchgear, PDUs, and racks.
- Advanced conductors — Manufacturers of high-capacity conductor materials that carry more current than conventional transmission cable on the same structures.
