10月27日，云南電網公司所屬送變電工程公司在500千伏紅墨Ⅰ回線257號塔，成功實施了云南省首次500千伏緊湊型輸電線路帶電作業。這一項目的開展，填補了云南電網公司在500千伏緊湊型輸電線路帶電作業方面的空白，對于提高帶電作業水平、提高供電可靠率具有積極的意義。
緊(jin)湊型輸電(dian)(dian)(dian)(dian)線(xian)路(lu)(lu)具有(you)輸送(song)容量大、節約(yue)送(song)電(dian)(dian)(dian)(dian)走(zou)廊、經濟效益和社會(hui)效益顯著等(deng)優(you)點(dian)，目前云南(nan)電(dian)(dian)(dian)(dian)網(wang)公(gong)司(si)(si)已擁有(you)緊(jin)湊型線(xian)路(lu)(lu)1276公(gong)里。由于500千(qian)(qian)伏緊(jin)湊型線(xian)路(lu)(lu)結構復雜(za)，空氣絕緣間(jian)隙小，開展(zhan)帶(dai)(dai)電(dian)(dian)(dian)(dian)作(zuo)業(ye)存在(zai)著很大的技術難度。送(song)變電(dian)(dian)(dian)(dian)工程公(gong)司(si)(si)于2008年11月成立(li)了(le)(le)(le)專門小組進(jin)行攻關(guan)，前期共進(jin)行了(le)(le)(le)6次模擬帶(dai)(dai)電(dian)(dian)(dian)(dian)作(zuo)業(ye)，并聯合相關(guan)有(you)關(guan)廠家設計研制(zhi)了(le)(le)(le)專門用于500千(qian)(qian)伏緊(jin)湊型線(xian)路(lu)(lu)帶(dai)(dai)電(dian)(dian)(dian)(dian)作(zuo)業(ye)的工器具，經過充分(fen)準備，成功完(wan)成了(le)(le)(le)此次帶(dai)(dai)電(dian)(dian)(dian)(dian)作(zuo)業(ye)。下一步，該公(gong)司(si)(si)將編制(zhi)完(wan)成云南(nan)電(dian)(dian)(dian)(dian)網(wang)公(gong)司(si)(si)500千(qian)(qian)伏緊(jin)湊型線(xian)路(lu)(lu)帶(dai)(dai)電(dian)(dian)(dian)(dian)作(zuo)業(ye)指導書(shu)。
