AC traction power supply | Rail Electrification | Global contrast to conventional transmission or distribution networks, traction power transformers typically feed 1-pole traction power supply systems with nominal phase-to-earth voltage of 15 kV or 25 kV. These are typically built as oil-immersed transformers with air-natural or air-forced cooling with a nominal power between 5 to 85 MVA.

High-voltage direct current - Wikipedia high-voltage, direct current (HVDC) electric power transmission system (also called a power superhighway or an electrical superhighway) uses direct current (DC) for the bulk transmission of electrical power, in contrast with the more common alternating current (AC) systems.. Most HVDC links use voltages between 100 kV and 800 kV. A 1,100 kV link in China was completed in 2019 over a …
ABB transformers enable world record transmission link in ... transformer technology will enable UHVDC transmission links to transmit up to 10,000 megawatts (MW) of electricity, setting a new world record in terms of capacity at the 800 kilovolt (kV) voltage level. The windswept steppes and arid desert of Inner Mongolia seem unlikely places to address China's energy challenges.
