銅包(bao)鋁和純銅進行以下(xia)四方面的比較：

機械特性：

純(chun)銅導(dao)(dao)體(ti)強(qiang)度(du)(du)、伸長率(lv)比(bi)(bi)銅包(bao)鋁(lv)(lv)(lv)導(dao)(dao)體(ti)大，也(ye)就是(shi)說純(chun)銅在機械性(xing)(xing)能(neng)方面比(bi)(bi)銅包(bao)鋁(lv)(lv)(lv)好(hao)。從電(dian)纜(lan)(lan)設計的(de)(de)角(jiao)度(du)(du)來(lai)看，純(chun)銅導(dao)(dao)體(ti)比(bi)(bi)銅包(bao)鋁(lv)(lv)(lv)導(dao)(dao)體(ti)機械強(qiang)度(du)(du)好(hao)的(de)(de)優(you)點，在實際應(ying)用過程中不一(yi)定需要。銅包(bao)鋁(lv)(lv)(lv)導(dao)(dao)體(ti)比(bi)(bi)純(chun)銅輕很多，因(yin)此銅包(bao)鋁(lv)(lv)(lv)的(de)(de)電(dian)纜(lan)(lan)在整體(ti)重量上比(bi)(bi)純(chun)銅導(dao)(dao)體(ti)電(dian)纜(lan)(lan)要輕，這樣會給電(dian)纜(lan)(lan)的(de)(de)運輸和電(dian)纜(lan)(lan)的(de)(de)架設施工帶(dai)來(lai)方便。另外(wai)銅包(bao)鋁(lv)(lv)(lv)比(bi)(bi)純(chun)銅軟(ruan)(ruan)一(yi)點，用銅包(bao)鋁(lv)(lv)(lv)導(dao)(dao)體(ti)生產的(de)(de)電(dian)纜(lan)(lan)在柔軟(ruan)(ruan)性(xing)(xing)方面比(bi)(bi)純(chun)銅的(de)(de)電(dian)纜(lan)(lan)好(hao)一(yi)點。

電氣性能：

因為鋁(lv)的導電(dian)(dian)性比銅差，使得(de)銅包鋁(lv)導體(ti)的直流電(dian)(dian)阻比純銅導體(ti)大(da)，這點有無影響主(zhu)要 2014年中考沖(chong)刺綜合復習指導北京地區試提 廣東地區試提

看電(dian)(dian)(dian)纜(lan)是否(fou)會被用(yong)供電(dian)(dian)(dian)，如給放大器(qi)提(ti)供電(dian)(dian)(dian)源，如果被用(yong)來供電(dian)(dian)(dian)的(de)(de)(de)(de)(de)話，銅(tong)包鋁導(dao)(dao)(dao)體(ti)將(jiang)會導(dao)(dao)(dao)致額外的(de)(de)(de)(de)(de)電(dian)(dian)(dian)力消耗(hao)，電(dian)(dian)(dian)壓降低較多(duo)。當(dang)頻(pin)率超(chao)過5MHz時，此(ci)時的(de)(de)(de)(de)(de)交流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)阻衰(shuai)減在(zai)這兩種不同的(de)(de)(de)(de)(de)導(dao)(dao)(dao)體(ti)下沒有明(ming)顯的(de)(de)(de)(de)(de)區(qu)別。當(dang)然(ran)，這主要是因(yin)為(wei)高(gao)(gao)頻(pin)電(dian)(dian)(dian)流(liu)(liu)(liu)(liu)的(de)(de)(de)(de)(de)集膚效應(ying)，頻(pin)率越(yue)高(gao)(gao)，電(dian)(dian)(dian)流(liu)(liu)(liu)(liu)的(de)(de)(de)(de)(de)流(liu)(liu)(liu)(liu)動就越(yue)接近導(dao)(dao)(dao)體(ti)表面(mian)，在(zai)銅(tong)包鋁導(dao)(dao)(dao)體(ti)的(de)(de)(de)(de)(de)表面(mian)實(shi)際上純銅(tong)材料，當(dang)頻(pin)率高(gao)(gao)到一(yi)定時候(hou)，整個電(dian)(dian)(dian)流(liu)(liu)(liu)(liu)鍍在(zai)銅(tong)材質里面(mian)流(liu)(liu)(liu)(liu)動了。在(zai)5MHz情況下，電(dian)(dian)(dian)流(liu)(liu)(liu)(liu)在(zai)近表面(mian)的(de)(de)(de)(de)(de)約(yue)(yue)0.025毫(hao)米(mi)厚(hou)度(du)中流(liu)(liu)(liu)(liu)動，漆包線，而銅(tong)包鋁導(dao)(dao)(dao)體(ti)的(de)(de)(de)(de)(de)銅(tong)層厚(hou)度(du)比此(ci)厚(hou)度(du)多(duo)約(yue)(yue)一(yi)倍(bei)。對于同軸電(dian)(dian)(dian)纜(lan)，因(yin)為(wei)傳輸(shu)的(de)(de)(de)(de)(de)信號是在(zai)5MHz以上，因(yin)此(ci)銅(tong)包鋁導(dao)(dao)(dao)體(ti)和(he)純銅(tong)導(dao)(dao)(dao)體(ti)傳輸(shu)效果是相同的(de)(de)(de)(de)(de)。在(zai)實(shi)際測試電(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)(de)衰(shuai)減可以證明(ming)這一(yi)點。
