Wednesday, January 7, 2009
ABB has introduced a new type of high-voltage transformer that can be used in power superhighways which can transit major amount of electrical power over long distances. This new 800 kV high voltage transformer will be used in the World's highest and longest voltage power transmission link, located in china. This 2000km ultra high voltage direct current transmission corridor will run from Xiangjiaba hydropower plant in western china to shanghai. This high voltage power transformer has a capacity of 6,400MW, which can supply current to nearly 31 million people. State Grid Corporation of china was the first to order this type of transformer. ABB is trying to change the current from AC to DC and also to raise the voltage for transmission. UHVDC technology is suitable for countries like china, where power generation facilities are often far from where output is used.
