11月14日(ri)16時05分，東(dong)(dong)北(bei)地(di)區(qu)首條630平方毫米截面積海(hai)纜輸電線路66千伏(fu)王(wang)海(hai)線于遼寧大連長海(hai)縣成功送(song)電，正式開啟(qi)東(dong)(dong)北(bei)地(di)區(qu)海(hai)纜智(zhi)能(neng)運維管(guan)理新階段。
長(chang)(chang)海(hai)縣是(shi)東北地區(qu)(qu)唯(wei)一的(de)海(hai)島(dao)(dao)邊境縣，地處(chu)遼(liao)東半(ban)島(dao)(dao)東側，氣候宜人、自(zi)然環境優越、漁業資源豐富，是(shi)消夏(xia)避暑的(de)勝(sheng)地。海(hai)島(dao)(dao)地區(qu)(qu)特殊的(de)地理環境和復雜海(hai)底(di)條(tiao)件對電(dian)(dian)(dian)網的(de)協調發(fa)展提出的(de)挑戰，嚴重制約著長(chang)(chang)海(hai)地區(qu)(qu)的(de)經濟發(fa)展。為強化(hua)電(dian)(dian)(dian)網網架(jia)，提升海(hai)島(dao)(dao)供電(dian)(dian)(dian)可靠(kao)性，國網大連(lian)供電(dian)(dian)(dian)公司整合(he)資源，全(quan)力爭(zheng)取66千伏王海(hai)線線路改造工程，切實(shi)將電(dian)(dian)(dian)力營商環境建設工作落到實(shi)處(chu)，助力長(chang)(chang)海(hai)縣經濟發(fa)展。
66千(qian)伏王海(hai)線(xian)線(xian)路改(gai)造工(gong)(gong)程(cheng)總投(tou)資2.02億元人民幣，共計改(gai)建輸電(dian)架空線(xian)路5.067公(gong)里(li)、新(xin)建海(hai)底(di)電(dian)纜20.11公(gong)里(li)。工(gong)(gong)程(cheng)自2023年3月(yue)正(zheng)式開工(gong)(gong)建設，11月(yue)14日正(zheng)式竣工(gong)(gong)投(tou)產，施工(gong)(gong)過程(cheng)中，克服(fu)了海(hai)島(dao)交通(tong)運輸難、海(hai)域海(hai)況天(tian)氣復雜等(deng)種種難題，歷時8個月(yue)的(de)艱苦施工(gong)(gong)，確保了工(gong)(gong)程(cheng)按期(qi)投(tou)產。
66千(qian)(qian)伏王(wang)海(hai)(hai)(hai)線線路改造工程首(shou)次選用(yong)630平(ping)方毫(hao)米截面積的(de)海(hai)(hai)(hai)底(di)光(guang)電復合(he)電纜(lan)(lan)，滿(man)足(zu)負荷增長需求(qiu)(qiu)同時，還能(neng)滿(man)足(zu)信息通(tong)訊需求(qiu)(qiu)，實現(xian)(xian)(xian)“一條海(hai)(hai)(hai)纜(lan)(lan)多種用(yong)途”。配套(tao)建設海(hai)(hai)(hai)纜(lan)(lan)智慧(hui)在線監(jian)控(kong)系統(tong)，通(tong)過海(hai)(hai)(hai)纜(lan)(lan)自(zi)帶的(de)光(guang)纖實現(xian)(xian)(xian)海(hai)(hai)(hai)纜(lan)(lan)運維全天候智能(neng)監(jian)控(kong)。海(hai)(hai)(hai)纜(lan)(lan)敷設施工首(shou)次采用(yong)拖拽式潛水器綜合(he)監(jian)控(kong)導航系統(tong)，可實現(xian)(xian)(xian)海(hai)(hai)(hai)纜(lan)(lan)路由敷設精準(zhun)掌控(kong)。新設備、新技術的(de)應(ying)用(yong)填補了(le)東(dong)北(bei)地(di)(di)區(qu)海(hai)(hai)(hai)纜(lan)(lan)智能(neng)化(hua)(hua)運維空白(bai)，為全面實現(xian)(xian)(xian)東(dong)北(bei)地(di)(di)區(qu)海(hai)(hai)(hai)纜(lan)(lan)智能(neng)化(hua)(hua)運維奠(dian)定了(le)基礎。 66千(qian)(qian)伏王(wang)海(hai)(hai)(hai)線的(de)順利投產后，供電能(neng)力將增加1倍，有效地(di)(di)提升了(le)地(di)(di)區(qu)供電可靠(kao)性。
