Successful Test Of 800-kilovolt Transformer

摘要

A new transformer developed for one of the world's longest and highest-rated high-voltage DC transmission systems (HVDC) has successfully completed final testing. It is the first HVDC transformer for 800 kilovolts (kV). Today's HVDC transmission systems normally operate at a peak transmission voltage of 500 kilovolts. The unit, which is the size of a family house, is destined for China. Siemens is delivering ten of these new high-performance transformers for the Yunnan-Guangdong HVDC system, which from mid-2010 onward will be transmitting 5,000 megawatts (MW) of power over a distance of 1,400 kilometres. HVDC solutions form part of Siemens' environmental portfolio, which generated €17 billion in sales for the company last year.
