2021-8-13 · From the national grid 400kV or 132kV transmission lines, 33kV or 11kV power cables are installed into lineside substations. Sometimes these cables are part of the railway infrastructure and run in trackside troughing routes. The substations are typically 3-4 miles apart and incorporate a transformer rectifier to obtain the 750V DC.
