由于電(dian)(dian)(dian)纜(lan)運行工況復雜(za)，在(zai)(zai)含有電(dian)(dian)(dian)解質的(de)(de)環(huan)境(jing)中，電(dian)(dian)(dian)極電(dian)(dian)(dian)位(wei)更低的(de)(de)鋁與其(qi)他(ta)加入的(de)(de)金屬元(yuan)素存在(zai)(zai)電(dian)(dian)(dian)極差，從而形(xing)成(cheng)電(dian)(dian)(dian)流通路，發生(sheng)孔蝕(shi)(shi)和(he)裂隙腐(fu)蝕(shi)(shi)等(deng)電(dian)(dian)(dian)化(hua)(hua)學現(xian)(xian)象。鋁和(he)鋁合(he)金接頭發生(sheng)氧化(hua)(hua)生(sheng)成(cheng)的(de)(de)氧化(hua)(hua)鋁是絕緣(yuan)體(ti)，質地堅硬、粘結力強的(de)(de)特性使其(qi)難以形(xing)成(cheng)良好的(de)(de)導電(dian)(dian)(dian)觸(chu)(chu)點(dian)，易造(zao)成(cheng)觸(chu)(chu)點(dian)發熱。鋁合(he)金改善(shan)了純鋁的(de)(de)抗拉(la)強度(du)，鋁合(he)金電(dian)(dian)(dian)纜(lan)可支撐(cheng)4000米(mi)長度(du)的(de)(de)自重(zhong)，銅電(dian)(dian)(dian)纜(lan)只(zhi)能支撐(cheng)2750米(mi)。這種優(you)勢在(zai)(zai)大跨度(du)的(de)(de)建筑（如體(ti)育場館）配線(xian)時體(ti)現(xian)(xian)得尤為(wei)突出。

鋁(lv)(lv)(lv)合金(jin)(jin)電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜所具(ju)備的(de)(de)良好(hao)的(de)(de)機(ji)(ji)械(xie)性(xing)能和電(dian)(dian)(dian)(dian)性(xing)能，使得它可以(yi)廣泛(fan)應用(yong)于(yu)國(guo)民(min)經(jing)濟的(de)(de)各個(ge)領域(yu)，如普通民(min)宅、高層(ceng)建(jian)筑、電(dian)(dian)(dian)(dian)梯、大(da)(da)小型超市商場、地鐵(tie)、機(ji)(ji)場、車(che)站、醫院、銀行(xing)(xing)、寫字(zi)樓、賓館酒店、郵政電(dian)(dian)(dian)(dian)信大(da)(da)樓、展覽館、圖書館、博物館、古代建(jian)筑、學校、電(dian)(dian)(dian)(dian)力大(da)(da)樓、公共娛(yu)樂場所、隧道、地下建(jian)筑、倉庫(ku)等。鋁(lv)(lv)(lv)合金(jin)(jin)有(you)很好(hao)的(de)(de)彎曲性(xing)能，其的(de)(de)合金(jin)(jin)配方、加(jia)工(gong)工(gong)藝(yi)，使柔韌(ren)性(xing)大(da)(da)幅提高。鋁(lv)(lv)(lv)合金(jin)(jin)比(bi)銅(tong)柔韌(ren)性(xing)高30%，高壓電(dian)(dian)(dian)(dian)纜廠家(jia)，反(fan)彈性(xing)比(bi)銅(tong)低(di)40%。一般銅(tong)纜的(de)(de)彎曲半徑(jing)為10~20倍(bei)外徑(jing)，而鋁(lv)(lv)(lv)合金(jin)(jin)電(dian)(dian)(dian)(dian)纜彎曲半徑(jing)僅為7倍(bei)外徑(jing)，更容易進行(xing)(xing)端(duan)子連接。中(zhong)強度(du)(du)全鋁(lv)(lv)(lv)合金(jin)(jin)導(dao)(dao)線(xian)(xian)(xian)的(de)(de)應用(yong)優(you)點：收磨損幾率較小。全鋁(lv)(lv)(lv)合金(jin)(jin)導(dao)(dao)線(xian)(xian)(xian)的(de)(de)硬度(du)(du)比(bi)較高，目(mu)前已經(jing)能夠達(da)到(dao)85HB的(de)(de)布(bu)氏(shi)硬度(du)(du).是鋁(lv)(lv)(lv)線(xian)(xian)(xian)材(cai)料(liao)的(de)(de)2倍(bei)。這種材(cai)料(liao)要輕(qing)于(yu)鋼(gang)芯鋁(lv)(lv)(lv)絞線(xian)(xian)(xian)，在對輸(shu)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)路(lu)建(jian)造的(de)(de)過程(cheng)(cheng)中(zhong).放線(xian)(xian)(xian)環節可以(yi)降低(di)表面受(shou)到(dao)的(de)(de)摩(mo)擦，讓線(xian)(xian)(xian)路(lu)的(de)(de)壽命延長。導(dao)(dao)線(xian)(xian)(xian)表面的(de)(de)高質址能夠在輸(shu)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)路(lu)運(yun)行(xing)(xing)的(de)(de)過程(cheng)(cheng)中(zhong)降低(di)運(yun)行(xing)(xing)時候產生的(de)(de)無線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)干擾程(cheng)(cheng)度(du)(du)以(yi)及電(dian)(dian)(dian)(dian)暈(yun)報(bao)失。
