HVDC projects for long-distance transmission have two (or rarely, more) converter stations and a transmission line interconnecting them. Generally overhead lines are used for interconnection, but an important class of HVDC projects use submarine power cables.
WebThe voltage is then stepped up by the power station transformer to a higher voltage (115 kV to 765 kV AC) for transmission. In the United States, power transmission is, variously, 230 kV to 500 kV, with less than 230 kV or … WebOne 735-kV line is equal to four 315-kV lines, the next voltage level down. In fact, Hydro-Québec is a pioneer in high-voltage power transmission: it developed the world's first commercial 735-kV line, as well as the earliest equipment designed for that voltage. In 1965, the first ever 735-kV power line was commissioned, linking the Manic ...
