5月15日，葛洲壩集團機電建設公司因優質高效安裝高寒、高海拔地區——拉西瓦水電站750千伏超高壓輸變電設備，受到業主黃河上游水電開發公司的表彰。
拉西瓦(wa)水(shui)電(dian)(dian)(dian)(dian)站位于(yu)青海省貴德縣境(jing)內(nei)的(de)(de)黃河上游，是(shi)黃河上游裝機(ji)容量最(zui)大(da)(da)的(de)(de)水(shui)電(dian)(dian)(dian)(dian)站。其750千(qian)伏(fu)超高(gao)壓(ya)輸變電(dian)(dian)(dian)(dian)設備是(shi)目(mu)前世(shi)界(jie)上首(shou)次(ci)在高(gao)海拔和(he)高(gao)寒地區安(an)裝的(de)(de)最(zui)高(gao)電(dian)(dian)(dian)(dian)壓(ya)等級輸變電(dian)(dian)(dian)(dian)設備，主要包括氣(qi)體絕緣開關(guan)（GIS）和(he)氣(qi)體絕緣金屬封閉輸電(dian)(dian)(dian)(dian)線路（GIL），首(shou)次(ci)使用(yong)的(de)(de)207米高(gao)落(luo)差(cha)氣(qi)體絕緣金屬封閉輸電(dian)(dian)(dian)(dian)線路管道也堪稱世(shi)界(jie)之最(zui)。安(an)裝技術(shu)(shu)難度(du)大(da)(da)，質量要求高(gao)，現場施工環境(jing)極其惡劣。葛(ge)洲壩集(ji)團機(ji)電(dian)(dian)(dian)(dian)建(jian)設公(gong)司拉西瓦(wa)機(ji)電(dian)(dian)(dian)(dian)安(an)裝項目(mu)部開展技術(shu)(shu)攻關(guan)，優化施工設計，確保了工程(cheng)建(jian)設順利進行。其負責安(an)裝的(de)(de)750千(qian)伏(fu)等級超高(gao)壓(ya)輸變電(dian)(dian)(dian)(dian)設備及電(dian)(dian)(dian)(dian)站公(gong)用(yong)系(xi)統的(de)(de)試驗(yan)均一次(ci)成功，為電(dian)(dian)(dian)(dian)站5月18日(ri)首(shou)批兩臺70萬(wan)千(qian)瓦(wa)機(ji)組(zu)正式(shi)投入運營奠定了堅實的(de)(de)基礎，良好業(ye)績(ji)受到業(ye)主、設計和(he)監(jian)理單位的(de)(de)高(gao)度(du)好評。
