| Strip-cast high-silicon electrical steelStandard Materials | Transformer and reactor cores | Cast on twin-roll lines close to final gauge, so it can carry more silicon than conventionally rolled steel tolerates. More silicon raises electrical resistivity, which cuts eddy-current and core losses in every transformer we build. |
|---|
| CopperQualified domestic mills | Windings, bus bars, and ground bus | High-conductivity copper for transformer windings and switchgear bus, where current density and short-circuit strength matter most. |
|---|
| AluminumQualified domestic mills | LV windings and busway | Used where weight and cost matter more than footprint, such as low-voltage windings and long busway runs. |
|---|
| Structural & stainless steelStandard Materials | Tanks, enclosures, and e-house frames | Transformer tanks, switchgear enclosures, and skid frames, fabricated alongside the cores so the whole unit comes out of one shop. |
