Cable types is one of key technologies in developing extra-high voltage(EHV) DC transmission lines design project. It has very big effect for the line transmission capacity, transmission performance, electromagnetic environment problems and transmission line´ technical and economic indexes. Because of economic reasonable select of wire section and structure and pole wire decorate. This paper aimed at nine ±660KV DC transmission lines wire scheme, research the electrical characteristics of wire scheme from current density, field effect, corona losses, radio interference, audible noise and so on. It is made a economic comparison between wire scheme by minimum cost method on one year. So pole wire scheme of NingDong-ShanDong ±660KV DC transmission line was confirmed. It is suggest this engineer dual-circuits adopts 6·LGJ-630/45 wire plan, Split spacing is 45cm; Single loop adopts 4·LGJ-800/55 wire scheme, Split spacing is 45cm.
