extra high voltage (EHV)

Electrical distribution networks are subdivided according to voltage into high-voltage networks, medium-voltage networks and low-voltage networks. In the case of high

voltage, there is a further differentiation towards extra high voltage.

Classification of the different voltage ranges

Classification of the different voltage ranges

Extra High Voltage (EHV) or Ultra High Voltage (UHV), and extra high voltage networks are those in which voltages of more than 220 kV(AC) are transmitted. Therefore, extra high voltage networks, also known as electricity highways, are used to connect to power plants, for overhead power lines and to supply cities. Their voltage ratings are 220 kV, 380 kV, 500 kV and 700 kV. Maximum voltages above 800 kV belong to the ultra-high voltages.
