機(ji)械(xie)特性。純(chun)銅(tong)導(dao)體強(qiang)度(du)、伸(shen)長(chang)率(lv)比銅(tong)包(bao)鋁導(dao)體大(da)，也就是(shi)說(shuo)純(chun)銅(tong)在機(ji)械(xie)性能方(fang)面(mian)比銅(tong)包(bao)鋁好。從(cong)電(dian)纜設(she)計(ji)的(de)角度(du)來看(kan)，純(chun)銅(tong)導(dao)體比銅(tong)包(bao)鋁導(dao)體機(ji)械(xie)強(qiang)度(du)好的(de)優(you)點(dian)，在實際(ji)應用(yong)過(guo)程(cheng)中(zhong)不壹定需要(yao)。銅(tong)包(bao)鋁導(dao)體比純(chun)銅(tong)輕很(hen)多，因(yin)此(ci)銅(tong)包(bao)鋁的(de)電(dian)纜在整體重量上比純(chun)銅(tong)導(dao)體電(dian)纜要(yao)輕，這(zhe)樣會(hui)給(gei)電(dian)纜的(de)運(yun)輸和(he)電(dian)纜的(de)架設(she)施(shi)工帶來(lai)方(fang)便。另(ling)外銅(tong)包(bao)鋁比純(chun)銅(tong)軟壹(yi)點，用(yong)銅(tong)包(bao)鋁導(dao)體生產(chan)的(de)電(dian)纜在柔(rou)軟性方(fang)面(mian)比純(chun)銅(tong)的(de)電(dian)纜好壹(yi)點。

電(dian)氣性能。因(yin)為(wei)鋁的(de)導(dao)電(dian)性比銅(tong)差(cha)，使(shi)得銅(tong)包(bao)鋁導(dao)體的(de)直流(liu)電(dian)阻比純(chun)銅(tong)導(dao)體大(da)，這點(dian)有無影響主要(yao)看(kan)電(dian)纜是(shi)否(fou)會(hui)被(bei)用(yong)來供(gong)電(dian)，如給(gei)放大(da)器提(ti)供(gong)電(dian)源，如(ru)果(guo)被(bei)用(yong)來供(gong)電(dian)的(de)話(hua)，銅(tong)包(bao)鋁導(dao)體將會(hui)導(dao)致(zhi)額(e)外的(de)電(dian)力(li)消(xiao)耗，電(dian)壓降低較多。當頻(pin)率(lv)超(chao)過(guo)5MHz時，此(ci)時的(de)交(jiao)流(liu)電(dian)阻衰(shuai)減在這兩(liang)種(zhong)不同(tong)的(de)導(dao)體下沒(mei)有明顯的(de)區別(bie)。當然(ran)，這(zhe)主要(yao)是(shi)因(yin)為(wei)高頻(pin)電(dian)流的(de)集膚(fu)效應，頻(pin)率(lv)越(yue)高，電(dian)流的(de)流動就越(yue)接(jie)近導(dao)體表面(mian)，在銅(tong)包(bao)鋁導(dao)體的(de)表面實(shi)際(ji)上純(chun)銅(tong)材料(liao)，當頻(pin)率(lv)高到壹(yi)定時候，整(zheng)個(ge)電(dian)流鍍(du)在銅(tong)材質(zhi)裏(li)面流(liu)動了。在5MHz情(qing)況下，電(dian)流在近表(biao)面的(de)約0.025毫米(mi)厚(hou)度(du)中(zhong)流動，而銅(tong)包(bao)鋁導(dao)體的(de)銅(tong)層厚(hou)度(du)比此(ci)厚(hou)度(du)多約(yue)壹倍。對(dui)於(yu)同(tong)軸電(dian)纜，因(yin)為(wei)傳輸的(de)信號是(shi)在5MHz以(yi)上，因(yin)此(ci)銅(tong)包(bao)鋁導(dao)體和(he)純(chun)銅(tong)導(dao)體傳輸效果(guo)是(shi)相同的(de)。在實際(ji)測試電(dian)纜的(de)衰(shuai)減可(ke)以(yi)證明(ming)這(zhe)壹點。銅(tong)包(bao)鋁較純(chun)銅(tong)導(dao)體軟，在生產(chan)過(guo)程(cheng)中(zhong)容(rong)易(yi)進(jin)行(xing)矯(jiao)直處理，因(yin)此(ci)在壹定(ding)程度(du)上可(ke)以(yi)說(shuo)用(yong)銅(tong)包(bao)鋁的(de)電(dian)纜要(yao)比用(yong)純(chun)銅(tong)導(dao)體的(de)電(dian)纜回(hui)波損耗指(zhi)標好。

經(jing)濟性。銅(tong)包(bao)鋁導(dao)體是(shi)按(an)重(zhong)量出(chu)售(shou)的(de)，純(chun)銅(tong)導(dao)體也是(shi)按(an)重(zhong)量出(chu)售(shou)的(de)，銅(tong)包(bao)鋁導(dao)體的(de)價(jia)格(ge)要(yao)比相同重(zhong)量的(de)純(chun)銅(tong)導(dao)體貴壹(yi)些(xie)。但(dan)是(shi)同(tong)樣重量的(de)銅(tong)包(bao)鋁要(yao)比純(chun)銅(tong)導(dao)體長(chang)度(du)長(chang)很(hen)多，而電(dian)纜是(shi)按(an)長(chang)度(du)計(ji)算的(de)。相同重(zhong)量，銅(tong)包(bao)鋁線是(shi)銅(tong)線長(chang)度(du)的(de)2.5倍，價(jia)格(ge)僅僅是(shi)每(mei)噸多幾百元(yuan)。綜合下來(lai)，銅(tong)包(bao)鋁就很(hen)有優(you)勢(shi)。由(you)於(yu)銅(tong)包(bao)鋁電(dian)纜比較(jiao)輕(qing)，電(dian)纜的(de)運(yun)輸成(cheng)本、安裝(zhuang)架(jia)設(she)成(cheng)本都(dou)會(hui)有所(suo)降低，會(hui)給(gei)施(shi)工帶來(lai)壹(yi)定的(de)方(fang)便性
