1月15日，舟山500千伏(fu)聯網輸變電工(gong)程投運。這是我國電力建設史上規模最大(da)、技術難度最大(da)的跨(kua)海(hai)聯網輸變電工(gong)程，創造了建設世(shi)界最高(gao)(gao)輸電高(gao)(gao)塔、敷設世(shi)界首(shou)條(tiao)500千伏(fu)交(jiao)聯聚乙烯海(hai)纜等14項世(shi)界紀錄。

該(gai)工(gong)(gong)程新建(jian)(jian)的(de)(de)(de)兩座(zuo)380米輸電(dian)(dian)(dian)(dian)(dian)高塔，采(cai)用同(tong)塔混壓(ya)四回線路，打破了輸電(dian)(dian)(dian)(dian)(dian)鐵(tie)塔高度、重(zhong)量、高塔基礎邊(bian)長等十(shi)項世界(jie)紀錄。工(gong)(gong)程敷設的(de)(de)(de)世界(jie)首條500千(qian)伏交(jiao)聯聚乙烯海(hai)(hai)(hai)纜，為自(zi)主研發生產，其應用解除了我(wo)國對500千(qian)伏進(jin)口海(hai)(hai)(hai)纜的(de)(de)(de)依(yi)賴。海(hai)(hai)(hai)纜施(shi)(shi)工(gong)(gong)應用的(de)(de)(de)施(shi)(shi)工(gong)(gong)船“啟帆9號”，是我(wo)國獨立設計生產的(de)(de)(de)先(xian)進(jin)海(hai)(hai)(hai)纜施(shi)(shi)工(gong)(gong)船，為海(hai)(hai)(hai)纜敷設提供了可(ke)靠的(de)(de)(de)裝(zhuang)備技(ji)術(shu)支撐(cheng)。新建(jian)(jian)成的(de)(de)(de)威遠變(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)是我(wo)國首座(zuo)建(jian)(jian)設在海(hai)(hai)(hai)洋灘涂上(shang)的(de)(de)(de)500千(qian)伏變(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)，標(biao)志著國家(jia)電(dian)(dian)(dian)(dian)(dian)網有(you)限公司成熟掌(zhang)握了在海(hai)(hai)(hai)洋灘涂上(shang)建(jian)(jian)造(zao)500千(qian)伏變(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)的(de)(de)(de)關鍵技(ji)術(shu)。一系列重(zhong)大突破，表(biao)明我(wo)國掌(zhang)握了先(xian)進(jin)的(de)(de)(de)海(hai)(hai)(hai)洋輸電(dian)(dian)(dian)(dian)(dian)技(ji)術(shu)，以“中國制造(zao)”解決世界(jie)難題。
