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(xi)(xi)瓦水電(dian)(dian)(dian)站(zhan)位(wei)于青海(hai)省貴德縣境(jing)內的黃(huang)(huang)河上(shang)(shang)游，是(shi)黃(huang)(huang)河上(shang)(shang)游裝機(ji)容量最(zui)大(da)(da)的水電(dian)(dian)(dian)站(zhan)。其750千伏(fu)超高(gao)壓輸(shu)變(bian)電(dian)(dian)(dian)設(she)備是(shi)目前世(shi)界上(shang)(shang)首(shou)次在高(gao)海(hai)拔和高(gao)寒地區安(an)裝的最(zui)高(gao)電(dian)(dian)(dian)壓等(deng)級(ji)輸(shu)變(bian)電(dian)(dian)(dian)設(she)備，主要包括氣體絕緣開(kai)關（GIS）和氣體絕緣金屬(shu)封(feng)閉輸(shu)電(dian)(dian)(dian)線路(lu)（GIL），首(shou)次使用的207米高(gao)落差氣體絕緣金屬(shu)封(feng)閉輸(shu)電(dian)(dian)(dian)線路(lu)管道也堪稱世(shi)界之最(zui)。安(an)裝技術(shu)(shu)難(nan)度大(da)(da)，質量要求高(gao)，現場(chang)施(shi)工(gong)環境(jing)極其惡劣。葛洲壩集團機(ji)電(dian)(dian)(dian)建(jian)設(she)公(gong)司拉西(xi)(xi)瓦機(ji)電(dian)(dian)(dian)安(an)裝項目部(bu)開(kai)展技術(shu)(shu)攻關，優化施(shi)工(gong)設(she)計(ji)(ji)，確保了(le)工(gong)程建(jian)設(she)順利進行。其負(fu)責(ze)安(an)裝的750千伏(fu)等(deng)級(ji)超高(gao)壓輸(shu)變(bian)電(dian)(dian)(dian)設(she)備及電(dian)(dian)(dian)站(zhan)公(gong)用系統(tong)的試驗均一(yi)次成功，為電(dian)(dian)(dian)站(zhan)5月18日首(shou)批兩臺70萬(wan)千瓦機(ji)組正式投入運營(ying)奠定了(le)堅實的基(ji)礎(chu)，良好(hao)業績(ji)受到業主、設(she)計(ji)(ji)和監理單位(wei)的高(gao)度好(hao)評。
