8. When to use medium-voltage cables
Three ranges of voltages are available for cables today. Low-voltage designs—often those used in industrial settings—are rated to 2,000 V or lower. Medium voltage designs range from 2,000 to 35,000 V and high-voltage cables are those rated above 35,000 V.
Medium-voltage cables are commonly used in mobile substation equipment, for distribution of power in industrial settings and in mining to supply power to drills, shovels, haulers, etc., said David Sedivy, Senior Product Manager at TPC Wire & Cable Corp. These cables often come in standard voltages, including 5,000; 8,000; 15,000; 25,000; and 35,000 V.
