輕型高壓直流輸電技術加強電網建設和電力貿易. 瑞士蘇黎士（2007年11月9日）消息，領先的電力自動化技術集團ABB，從納米比亞國家電力部門NamPower處獲得18000萬美元合同，用于連接國內兩部分電網并加強南非電絡建設. NamPower正在修建連接Caprivi 地區和納米比亞中部電網的350千伏300兆瓦的電力傳輸線.這條傳輸線還可以使納米比亞、贊比亞、津巴布韋、剛果民主共和國、莫桑比克和南非國家之間的電力網相互連接，創建一個來自鄰國的用于電力輸入輸出的選擇性路線. 此設計允許延伸功率達到600MW. 此條電力連接線將使用ABB創新且環保的輕型高壓直流輸電系統，高壓直流輸電技術將加強電網的不牢固性，提高區域內部電網的可靠性. ABB電力系統部門Peter Leupp說：“新Caprivi內部連接線將在南非廣闊地區內建立電力貿易. 使電力資源在區域內得到更加有效地應用，包括可再生能源.” ABB負責整個系統工程，包括兩個交流站和接地極的設計、供應和安裝. 此工程使得輕型高壓直流輸電的電壓可達350KV，標志著此技術將第一次被用于長距離電網架空送電線路. 此系統預計在2009年年底投入運營. ABB是電力自動化技術領域的全球領導廠商，致力于為工業和電力行業客戶提供解決方案，以幫助客戶提高生產效率，同時降低對環境的不良影響. ABB集團的業務遍布全球100多個國家，擁有大約118,000名雇員.

NamPower is building a 350 kilovolts （kV）, 300-megawatt （MW） transmission link between the northeastern Caprivi region and the power network in central Namibia. This link will also interconnect the electricity networks of Namibia, Zambia, Zimbabwe, the Democratic Republic of Congo, Mozambique and South Africa to create an alternative route for power imports and exports to and from neighboring countries. The design allows for an extension to 600MW. The link will use ABB’s innovative and environmentally friendly HVDC Light system, a high-voltage direct current transmission technology that will stabilize the two weak networks and increase grid reliability in the region. “The new Caprivi Link Interconnector will enable the establishment of power trading in the expansive region of southern Africa,” said Peter Leupp, head of ABB’s Power Systems division “It will allow a more efficient use of power resources in the region, including renewable energy.” ABB is responsible for system engineering including design, supply and installation of the two converter stations and earth electrodes. This project extends the voltage for HVDC Light to 350 kilovolts （kV） and marks the first time the technology will be used for long overhead transmission lines. The system is scheduled to be in operation by the end of 2009.
