輕型高壓直流輸電技術(shù)加強(qiáng)電網(wǎng)建設(shè)和電力貿(mào)易. 瑞士蘇黎士（2007年11月9日）消息，領(lǐng)先的電力自動化技術(shù)集團(tuán)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(nèi)兩部分電網(wǎng)并加強(qiáng)南非電絡(luò)建設(shè). NamPower正在修建連接Caprivi 地區(qū)和納米比亞中部電網(wǎng)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(wǎng)相互連接，創(chuàng)建一個(gè)來自鄰國的用于電力輸入輸出的選擇性路線. 此設(shè)計(jì)允許延伸功率達(dá)到600MW. 此條電力連接線將使用ABB創(chuàng)新且環(huán)保的輕型高壓直流輸電系統(tǒng)，高壓直流輸電技術(shù)將加強(qiáng)電網(wǎng)的不牢固性，提高區(qū)域內(nèi)部電網(wǎng)的可靠性. ABB電力系統(tǒng)部門Peter Leupp說：“新Caprivi內(nèi)部連接線將在南非廣闊地區(qū)內(nèi)建立電力貿(mào)易. 使電力資源在區(qū)域內(nèi)得到更加有效地應(yīng)用，包括可再生能源.” ABB負(fù)責(zé)整個(gè)系統(tǒng)工程，包括兩個(gè)交流站和接地極的設(shè)計(jì)、供應(yīng)和安裝. 此工程使得輕型高壓直流輸電的電壓可達(dá)350KV，標(biāo)志著此技術(shù)將第一次被用于長距離電網(wǎng)架空送電線路. 此系統(tǒng)預(yù)計(jì)在2009年年底投入運(yùn)營. ABB是電力自動化技術(shù)領(lǐng)域的全球領(lǐng)導(dǎo)廠商，致力于為工業(yè)和電力行業(yè)客戶提供解決方案，以幫助客戶提高生產(chǎn)效率，同時(shí)降低對環(huán)境的不良影響. ABB集團(tuán)的業(yè)務(wù)遍布全球100多個(gè)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.
