A voltage rating on a power cord is a function of the insulation, i.e. how much voltage can be withstood before arcing across the insulation. The diameter of the conductors, and the quality of the connectors determine how much amperage can be safely handled. So a cord rated for 600 volts is a good thing, i.e. lots of room for safety.
