穿行云端峭壁 守護華山“天路”

“電力天路”上的“送貨員”

12月6日，騾馬隊馱負工程物料前往山頂塔基施工現場(chǎng)。

2019年9月開(kāi)工建設的西藏阿里與藏中電網(wǎng)聯(lián)網(wǎng)工程是迄今為止世界上海拔最高的輸變電工程。在日喀則市桑珠孜區電網(wǎng)建設現場(chǎng)，由于海拔高、地勢險，加之高原缺氧，石料、水泥等建筑材料只能被車(chē)輛運輸到山腳下，再由騾馬隊運到位于山頂的塔基澆制施工現場(chǎng)。

據介紹，該工程起于日喀則市桑珠孜區多林220千伏變電站，止于阿里地區噶爾縣巴爾220千伏變電站，跨越西藏10個(gè)縣區，塔位平均海拔4572米，最高海拔5357米，穿越地形復雜，施工環(huán)境惡劣，是一條超高難度的“電力天路”。項目計劃于2021年建成投運，建成后將結束阿里電網(wǎng)長(cháng)期孤網(wǎng)運行歷史。
