Electricity network – MV
A medium voltage (MV) network distributes power from the transmission system to the end-users. The MV lines range typically from 10 to 70 kV and 1 to 100 MW. Users that demand high amounts of power (400kW-5MW) can be connected directly to medium voltage . Nevertheless, the distribution system will have a final voltage step down to deliver electricity at 400V. Typically medium voltage networks are composed of overhead lines. A single line describes a transmission or distribution cable connecting two points in the network, which has a specific rated capacity and unit costs.
