Difference between enameled, synthetic and super enameled copper conductors

[DUET]

Could someone please illustrate the difference among the following terms?

1. Enameled round copper conductor.
2. Synthetic enameled round copper conductor.
3. Supper enameled round copper conductor.

Thanks in advance.

These are just the type of insulation applied to the conductor. You would need the datasheet of the wire, or the enamel to compare the cost vs benefit.
