Application:

Medium voltage cables are used for power distribution in medium voltage, as transformer feeders in distribution substations. These lines can be found in many installations, such as in power plants, residential areas and mining operations, suitable for use in both dry and wet locations. They can be laid in air or directly buried in the ground or in ducts, providing good mechanical protection.
