9月底，由(you)新疆(jiang)送變(bian)電工(gong)(gong)程公司(si)承擔的220千伏玉龍(long)河—莎車輸(shu)變(bian)電工(gong)(gong)程首(shou)次采用飛艇(ting)展放(fang)引(yin)繩(sheng)新工(gong)(gong)藝(yi)。這一施(shi)工(gong)(gong)工(gong)(gong)藝(yi)，不(bu)(bu)僅能使沿(yan)線農作物(wu)、樹木免(mian)受砍伐(fa)之苦，使電力職工(gong)(gong)不(bu)(bu)再徒步跨越(yue)障礙，同時(shi)大大縮短了工(gong)(gong)期、節約(yue)了成本。
220千(qian)伏(fu)玉莎(sha)線(xian)由莎(sha)車220千(qian)伏(fu)變電(dian)(dian)所(suo)出線(xian)向東，跨越(yue)(yue)葉爾羌(qiang)河(he)(he)，通(tong)過澤(ze)普(pu)南部(bu)，跨越(yue)(yue)315國道，跨越(yue)(yue)提茲(zi)那甫河(he)(he)，通(tong)過葉城縣北部(bu)，跨越(yue)(yue)315國道，跨越(yue)(yue)喀拉喀拉河(he)(he)，進入和田(tian)玉龍220千(qian)伏(fu)變電(dian)(dian)所(suo)，線(xian)路全長286.278公(gong)里(li)。如果按照以往電(dian)(dian)力(li)施工展(zhan)放引繩(sheng)工序中人工牽引步(bu)行的(de)方式通(tong)過農田(tian)、跨越(yue)(yue)河(he)(he)流(liu)、翻過高山，不但(dan)耗時(shi)耗力(li)，而且影(ying)響到施工地點的(de)植被，青苗賠(pei)償(chang)成本也(ye)很高。為此，新(xin)(xin)疆(jiang)送變電(dian)(dian)首次將飛(fei)(fei)(fei)艇展(zhan)放引繩(sheng)新(xin)(xin)工藝應用(yong)到新(xin)(xin)疆(jiang)電(dian)(dian)網建(jian)設施工中。該公(gong)司引進的(de)YS-7型飛(fei)(fei)(fei)艇，艇囊用(yong)氦氣填充，充氣后(hou)自重僅為3公(gong)斤左(zuo)右，飛(fei)(fei)(fei)艇一次最長牽放引繩(sheng)的(de)長度為2500米，續航時(shi)間40分鐘，每次起(qi)飛(fei)(fei)(fei)后(hou)，地勤人員接力(li)遙控(kong)飛(fei)(fei)(fei)艇通(tong)過。
