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)瓦水(shui)電(dian)(dian)(dian)(dian)站位于青海省(sheng)貴德(de)縣境(jing)內的黃河上游，是黃河上游裝(zhuang)機容量最(zui)大的水(shui)電(dian)(dian)(dian)(dian)站。其(qi)(qi)750千(qian)伏超高(gao)(gao)(gao)(gao)(gao)壓輸(shu)(shu)變(bian)電(dian)(dian)(dian)(dian)設(she)備是目(mu)(mu)前世界上首(shou)次在高(gao)(gao)(gao)(gao)(gao)海拔和(he)高(gao)(gao)(gao)(gao)(gao)寒地區安裝(zhuang)的最(zui)高(gao)(gao)(gao)(gao)(gao)電(dian)(dian)(dian)(dian)壓等級(ji)輸(shu)(shu)變(bian)電(dian)(dian)(dian)(dian)設(she)備，主要包括氣(qi)體絕(jue)(jue)緣開關(guan)（GIS）和(he)氣(qi)體絕(jue)(jue)緣金屬封閉輸(shu)(shu)電(dian)(dian)(dian)(dian)線路（GIL），首(shou)次使用的207米高(gao)(gao)(gao)(gao)(gao)落(luo)差氣(qi)體絕(jue)(jue)緣金屬封閉輸(shu)(shu)電(dian)(dian)(dian)(dian)線路管(guan)道也堪稱世界之(zhi)最(zui)。安裝(zhuang)技術難度(du)(du)大，質量要求(qiu)高(gao)(gao)(gao)(gao)(gao)，現(xian)場施工(gong)環境(jing)極其(qi)(qi)惡劣。葛洲(zhou)壩(ba)集團機電(dian)(dian)(dian)(dian)建設(she)公司拉西(xi)瓦機電(dian)(dian)(dian)(dian)安裝(zhuang)項目(mu)(mu)部開展(zhan)技術攻關(guan)，優(you)化施工(gong)設(she)計(ji)，確(que)保了(le)工(gong)程建設(she)順利進(jin)行。其(qi)(qi)負責安裝(zhuang)的750千(qian)伏等級(ji)超高(gao)(gao)(gao)(gao)(gao)壓輸(shu)(shu)變(bian)電(dian)(dian)(dian)(dian)設(she)備及電(dian)(dian)(dian)(dian)站公用系統的試驗(yan)均一次成功，為電(dian)(dian)(dian)(dian)站5月(yue)18日首(shou)批兩臺(tai)70萬千(qian)瓦機組正式投入運營奠(dian)定了(le)堅實的基礎，良好業績受到業主、設(she)計(ji)和(he)監理單位的高(gao)(gao)(gao)(gao)(gao)度(du)(du)好評(ping)。
