Medium Voltage Single Core Power Cable

Medium voltage (MV) single core power cables are designed to transmit electrical power in systems with voltage ratings ranging typically from 3.6/6 kV to 26/35 kV. These cables are commonly used in industrial, utility, and infrastructure applications, including power distribution networks, renewable energy installations, and substations.
