電(dian)(dian)纜(lan)——電(dian)(dian)力應用的(de)基礎(chu)。在很多朋友的(de)認識(shi)里，或許都會以(yi)為電(dian)(dian)纜(lan)一般都是銅芯電(dian)(dian)纜(lan)或者鋁芯電(dian)(dian)纜(lan)。銅芯電(dian)(dian)纜(lan)和(he)鋁芯電(dian)(dian)纜(lan)的(de)質量確實毋庸(yong)置(zhi)疑(yi)，它(ta)們性能(neng)特點也已經經過了時間的(de)驗(yan)證，目(mu)前也已經占據了大部分(fen)電(dian)(dian)纜(lan)市場份額。

鋁(lv)(lv)(lv)(lv)(lv)(lv)合(he)金(jin)(jin)(jin)(jin)電(dian)(dian)(dian)纜(lan)(lan)，顧(gu)名思(si)義，就是由鋁(lv)(lv)(lv)(lv)(lv)(lv)合(he)金(jin)(jin)(jin)(jin)作(zuo)為導電(dian)(dian)(dian)材(cai)料而(er)制(zhi)作(zuo)而(er)成的(de)新(xin)型的(de)電(dian)(dian)(dian)纜(lan)(lan)。目前(qian)，制(zhi)作(zuo)鋁(lv)(lv)(lv)(lv)(lv)(lv)合(he)金(jin)(jin)(jin)(jin)電(dian)(dian)(dian)纜(lan)(lan)的(de)鋁(lv)(lv)(lv)(lv)(lv)(lv)合(he)金(jin)(jin)(jin)(jin)主要是AA8000系(xi)列的(de)鋁(lv)(lv)(lv)(lv)(lv)(lv)合(he)金(jin)(jin)(jin)(jin)，該系(xi)列的(de)鋁(lv)(lv)(lv)(lv)(lv)(lv)合(he)金(jin)(jin)(jin)(jin)已(yi)經被證明是最(zui)適合(he)制(zhi)作(zuo)電(dian)(dian)(dian)纜(lan)(lan)的(de)鋁(lv)(lv)(lv)(lv)(lv)(lv)合(he)金(jin)(jin)(jin)(jin)。目前(qian)，鋁(lv)(lv)(lv)(lv)(lv)(lv)合(he)金(jin)(jin)(jin)(jin)電(dian)(dian)(dian)纜(lan)(lan)在(zai)實(shi)際的(de)使用過程中，已(yi)經證明其具有替代銅芯電(dian)(dian)(dian)纜(lan)(lan)和鋁(lv)(lv)(lv)(lv)(lv)(lv)芯電(dian)(dian)(dian)纜(lan)(lan)的(de)潛力。那么鋁(lv)(lv)(lv)(lv)(lv)(lv)合(he)金(jin)(jin)(jin)(jin)電(dian)(dian)(dian)纜(lan)(lan)作(zuo)為一種(zhong)新(xin)型的(de)電(dian)(dian)(dian)纜(lan)(lan)，它擁有著那些主要性能特點呢(ni)?

一(yi)、與(yu)銅(tong)(tong)(tong)芯(xin)(xin)(xin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)和鋁(lv)芯(xin)(xin)(xin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)相比，鋁(lv)合(he)金(jin)(jin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)在導電(dian)(dian)(dian)(dian)(dian)(dian)(dian)率方面優于鋁(lv)芯(xin)(xin)(xin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)，在重量(liang)(liang)方面優于銅(tong)(tong)(tong)芯(xin)(xin)(xin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)。實(shi)(shi)驗證(zheng)明，在導電(dian)(dian)(dian)(dian)(dian)(dian)(dian)率方面，鋁(lv)芯(xin)(xin)(xin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的導電(dian)(dian)(dian)(dian)(dian)(dian)(dian)率是銅(tong)(tong)(tong)芯(xin)(xin)(xin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的66%左右，鋁(lv)合(he)金(jin)(jin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的導電(dian)(dian)(dian)(dian)(dian)(dian)(dian)率則是銅(tong)(tong)(tong)芯(xin)(xin)(xin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的80%左右，可(ke)見鋁(lv)合(he)金(jin)(jin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的導電(dian)(dian)(dian)(dian)(dian)(dian)(dian)率雖然不如銅(tong)(tong)(tong)芯(xin)(xin)(xin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)，但是其遠(yuan)遠(yuan)優于鋁(lv)芯(xin)(xin)(xin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)。在重量(liang)(liang)方面，實(shi)(shi)驗證(zheng)明，在相同電(dian)(dian)(dian)(dian)(dian)(dian)(dian)氣性能(neng)的前提(ti)下，鋁(lv)合(he)金(jin)(jin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的重量(liang)(liang)為銅(tong)(tong)(tong)芯(xin)(xin)(xin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的50%左右。所以，綜合(he)考慮，鋁(lv)合(he)金(jin)(jin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)完全可(ke)以取代(dai)鋁(lv)芯(xin)(xin)(xin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)，與(yu)銅(tong)(tong)(tong)芯(xin)(xin)(xin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)相比，可(ke)以有(you)效的減輕電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的重量(liang)(liang)，在降低成(cheng)本方面，具有(you)較大優勢。

二、與銅(tong)芯電(dian)(dian)(dian)(dian)纜(lan)(lan)和鋁芯電(dian)(dian)(dian)(dian)纜(lan)(lan)相比，鋁合(he)金電(dian)(dian)(dian)(dian)纜(lan)(lan)在(zai)(zai)抗蠕變性能、抗拉(la)(la)強度和延伸(shen)率方面(mian)，都比較可靠(kao)。鋁芯電(dian)(dian)(dian)(dian)纜(lan)(lan)和銅(tong)芯電(dian)(dian)(dian)(dian)纜(lan)(lan)一(yi)般在(zai)(zai)受(shou)熱或者(zhe)受(shou)壓情況下會出(chu)(chu)現不同程度的蠕變，導致電(dian)(dian)(dian)(dian)纜(lan)(lan)松(song)弛，而鋁合(he)金電(dian)(dian)(dian)(dian)纜(lan)(lan)都是通過了退火(huo)處理，不會出(chu)(chu)現較大蠕變，在(zai)(zai)抗拉(la)(la)伸(shen)方面(mian)具有(you)優勢。

三(san)、鋁(lv)合(he)金電(dian)纜在抗(kang)腐蝕(shi)和(he)阻(zu)燃方(fang)(fang)面，更(geng)加(jia)可(ke)靠。AA8000系列的鋁(lv)合(he)金是加(jia)入(ru)稀土制作(zuo)而成的，其在腐蝕(shi)和(he)阻(zu)燃上(shang)，遠(yuan)遠(yuan)優于(yu)純(chun)金屬。目前，鋁(lv)合(he)金電(dian)纜在美國(guo)的應(ying)用(yong)以及有了(le)四十多年，從應(ying)用(yong)至今，從未發生過鋁(lv)合(he)金電(dian)纜被腐蝕(shi)和(he)一起火災的情況。可(ke)見，鋁(lv)合(he)金電(dian)纜的在安全方(fang)(fang)面是相當可(ke)靠的。
