It's generally the same current rating no matter the voltage.

Depends a bit on whether you rate the cable for how hot you allow it
to get in a specified environment, or as here where the rating of a
cable is based on the allowable circuit voltage drop expressed as a
percentage of the nominal voltage over a specified length.

Environment is a factor. So is the number of other current carrying cables
packed with it.

But the OP gave no other details.
