擴(kuo)徑(jing)(jing)導線(xian)是以滿足技術(shu)條件的常(chang)規導線(xian)規格(ge)為基準，采(cai)取擴(kuo)大導線(xian)外(wai)(wai)徑(jing)(jing)技術(shu)，在保(bao)證電暈所(suo)要求的導線(xian)外(wai)(wai)徑(jing)(jing)前提下，減少導線(xian)的鋁(lv)截(jie)面，從(cong)而減少導線(xian)的總重量，減少鐵塔荷載和結構(gou)重量，極(ji)大地降低線(xian)路造價(jia)。

擴徑導線(xian)(xian)(xian)在超高(gao)壓(ya)(ya)和特高(gao)壓(ya)(ya)輸電(dian)(dian)(dian)工程(cheng)中有很大的應用空間，尤其在高(gao)海(hai)拔地(di)區(qu)有著更為廣(guang)闊的前(qian)景。擴徑鋼芯(xin)鋁絞線(xian)(xian)(xian)LGKK適用于高(gao)低(di)壓(ya)(ya)輸電(dian)(dian)(dian)線(xian)(xian)(xian)中電(dian)(dian)(dian)廠及變(bian)電(dian)(dian)(dian)站配電(dian)(dian)(dian)線(xian)(xian)(xian)路。

當線(xian)(xian)(xian)(xian)(xian)路的(de)電壓超過220kv時，為(wei)了降低線(xian)(xian)(xian)(xian)(xian)路電抗和電暈損耗，通常采用(yong)擴徑導線(xian)(xian)(xian)(xian)(xian)。擴徑導線(xian)(xian)(xian)(xian)(xian)就是把普通的(de)導線(xian)(xian)(xian)(xian)(xian)做成中空(kong)(kong)（里(li)面用(yong)多股鋼芯線(xian)(xian)(xian)(xian)(xian)和支撐(cheng)層(ceng)做成）或(huo)者減少其中部(bu)分層(ceng)單(dan)(dan)線(xian)(xian)(xian)(xian)(xian)數(shu)量（使該層(ceng)單(dan)(dan)線(xian)(xian)(xian)(xian)(xian)間存在一(yi)定(ding)數(shu)量空(kong)(kong)隙），最終達(da)到(dao)增加導線(xian)(xian)(xian)(xian)(xian)的(de)等效半徑的(de)目(mu)的(de)。
