Enameled CCA and Copper Wire
Set the winding resistance and space limits, then compare finished wire diameter, insulation, winding behavior and termination for the two conductor constructions.
Engineering comparison
Fill in the input cells, then copy the table and paste it into your inquiry. Leave unknown items blank.

| Decision | enameled CCA wire | enameled copper wire | Acceptance basis | Your input or result |
|---|---|---|---|---|
| Insulated construction | CCA metal core with a specified enamel system | Copper metal core with a specified enamel system | Separate metal diameter, enamel build and finished outer diameter. | |
| Winding design | Choose metal section and turns against the required resistance and slot space | Choose metal section and turns against the required resistance and slot space | Use equal finished-winding resistance and thermal duty rather than equal outer diameter. | |
| Processing | Confirm CCA surface, enamel adhesion, stripping and terminal approval | Confirm copper condition, enamel adhesion, stripping and terminal approval | Evaluate bend, cure, dielectric and termination tests with the actual insulation build. | |
| Availability and permission | Capability and enamel grade require engineering confirmation | Copper and enamel grade require order-specific confirmation | If the drawing requires copper, obtain specification-owner permission before a CCA trial. |
