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(la)西(xi)瓦(wa)(wa)水電(dian)(dian)(dian)(dian)站位于青(qing)海省貴德縣境內(nei)的(de)(de)(de)黃河(he)上游(you)，是黃河(he)上游(you)裝機(ji)容量(liang)最大(da)的(de)(de)(de)水電(dian)(dian)(dian)(dian)站。其(qi)750千(qian)伏超高(gao)壓輸變電(dian)(dian)(dian)(dian)設(she)備是目(mu)前世界上首次在高(gao)海拔(ba)和(he)高(gao)寒地區(qu)安(an)裝的(de)(de)(de)最高(gao)電(dian)(dian)(dian)(dian)壓等(deng)級(ji)輸變電(dian)(dian)(dian)(dian)設(she)備，主要(yao)包括(kuo)氣(qi)體絕緣開關（GIS）和(he)氣(qi)體絕緣金屬封閉(bi)輸電(dian)(dian)(dian)(dian)線路（GIL），首次使用的(de)(de)(de)207米高(gao)落(luo)差氣(qi)體絕緣金屬封閉(bi)輸電(dian)(dian)(dian)(dian)線路管道也(ye)堪稱世界之(zhi)最。安(an)裝技術難度大(da)，質(zhi)量(liang)要(yao)求高(gao)，現(xian)場施(shi)工(gong)環境極其(qi)惡劣。葛(ge)洲(zhou)壩集團(tuan)機(ji)電(dian)(dian)(dian)(dian)建設(she)公(gong)司(si)拉(la)西(xi)瓦(wa)(wa)機(ji)電(dian)(dian)(dian)(dian)安(an)裝項目(mu)部開展技術攻關，優(you)化施(shi)工(gong)設(she)計，確保了工(gong)程建設(she)順利(li)進(jin)行。其(qi)負責安(an)裝的(de)(de)(de)750千(qian)伏等(deng)級(ji)超高(gao)壓輸變電(dian)(dian)(dian)(dian)設(she)備及電(dian)(dian)(dian)(dian)站公(gong)用系統的(de)(de)(de)試(shi)驗(yan)均(jun)一次成功，為(wei)電(dian)(dian)(dian)(dian)站5月18日首批兩(liang)臺70萬千(qian)瓦(wa)(wa)機(ji)組(zu)正式投入運營奠定了堅實的(de)(de)(de)基礎，良好業績受到業主、設(she)計和(he)監理單位的(de)(de)(de)高(gao)度好評。
