What is the maximum voltage rating for which type MV cable is permitted for use?

The maximum voltage rating for type MV (Medium Voltage) cable is generally recognized as 35,000 volts. This classification is standard in the electrical industry for medium voltage applications, which typically span the voltage range of 2,400 volts up to 35,000 volts, depending on the specific regulations or guidelines set forth in various codes such as the National Electrical Code (NEC) or standards from organizations like the Institute of Electrical and Electronics Engineers (IEEE).

Understanding the voltage ratings helps ensure safe and effective design and operation of electrical systems. While cables rated for higher voltages, such as 40,000 volts, exist, they fall into the high voltage category rather than medium voltage. This is crucial for proper installation, equipment compatibility, and safety measures in electrical infrastructure.
