銅包鋁和(he)純銅進(jin)行以下四方(fang)面的(de)比(bi)較(jiao)：

機械特性：

純(chun)(chun)銅(tong)(tong)(tong)(tong)導(dao)體(ti)(ti)(ti)強度(du)、伸長率比(bi)(bi)(bi)銅(tong)(tong)(tong)(tong)包鋁(lv)(lv)導(dao)體(ti)(ti)(ti)大，也就是說純(chun)(chun)銅(tong)(tong)(tong)(tong)在機械性能方(fang)面比(bi)(bi)(bi)銅(tong)(tong)(tong)(tong)包鋁(lv)(lv)好。從電纜(lan)設計的角(jiao)度(du)來看，純(chun)(chun)銅(tong)(tong)(tong)(tong)導(dao)體(ti)(ti)(ti)比(bi)(bi)(bi)銅(tong)(tong)(tong)(tong)包鋁(lv)(lv)導(dao)體(ti)(ti)(ti)機械強度(du)好的優點，在實際應(ying)用過程(cheng)中不一定(ding)需要。銅(tong)(tong)(tong)(tong)包鋁(lv)(lv)導(dao)體(ti)(ti)(ti)比(bi)(bi)(bi)純(chun)(chun)銅(tong)(tong)(tong)(tong)輕很多，因此(ci)銅(tong)(tong)(tong)(tong)包鋁(lv)(lv)的電纜(lan)在整體(ti)(ti)(ti)重量(liang)上比(bi)(bi)(bi)純(chun)(chun)銅(tong)(tong)(tong)(tong)導(dao)體(ti)(ti)(ti)電纜(lan)要輕，這樣會給電纜(lan)的運輸和(he)電纜(lan)的架設施(shi)工帶來方(fang)便。另外銅(tong)(tong)(tong)(tong)包鋁(lv)(lv)比(bi)(bi)(bi)純(chun)(chun)銅(tong)(tong)(tong)(tong)軟一點，用銅(tong)(tong)(tong)(tong)包鋁(lv)(lv)導(dao)體(ti)(ti)(ti)生產(chan)的電纜(lan)在柔(rou)軟性方(fang)面比(bi)(bi)(bi)純(chun)(chun)銅(tong)(tong)(tong)(tong)的電纜(lan)好一點。

電氣性能：

因為鋁的導(dao)電性比(bi)銅(tong)差，使得(de)銅(tong)包(bao)鋁導(dao)體的直流電阻比(bi)純(chun)銅(tong)導(dao)體大，這點有無影響(xiang)主要 2014年中考沖刺綜合復習指導(dao)北京地區(qu)試提 廣東地區(qu)試提

看電(dian)(dian)(dian)(dian)纜(lan)是(shi)否(fou)會(hui)(hui)被用供(gong)電(dian)(dian)(dian)(dian)，如給放大器(qi)提供(gong)電(dian)(dian)(dian)(dian)源，如果(guo)被用來供(gong)電(dian)(dian)(dian)(dian)的(de)話，銅(tong)包鋁導(dao)(dao)體(ti)(ti)(ti)(ti)將會(hui)(hui)導(dao)(dao)致額外的(de)電(dian)(dian)(dian)(dian)力消耗，電(dian)(dian)(dian)(dian)壓(ya)降低較多(duo)。當頻(pin)率超過(guo)5MHz時，此時的(de)交流(liu)電(dian)(dian)(dian)(dian)阻衰減在(zai)(zai)這兩種不同的(de)導(dao)(dao)體(ti)(ti)(ti)(ti)下(xia)沒有明顯的(de)區(qu)別。當然，銅(tong)包鋁電(dian)(dian)(dian)(dian)纜(lan)，這主要是(shi)因(yin)為高(gao)頻(pin)電(dian)(dian)(dian)(dian)流(liu)的(de)集膚效應，頻(pin)率越高(gao)，電(dian)(dian)(dian)(dian)流(liu)的(de)流(liu)動(dong)就越接近導(dao)(dao)體(ti)(ti)(ti)(ti)表面，在(zai)(zai)銅(tong)包鋁導(dao)(dao)體(ti)(ti)(ti)(ti)的(de)表面實際上(shang)純銅(tong)材(cai)料，當頻(pin)率高(gao)到一定時候，銅(tong)包鋁線(xian)，整個電(dian)(dian)(dian)(dian)流(liu)鍍(du)在(zai)(zai)銅(tong)材(cai)質里面流(liu)動(dong)了。在(zai)(zai)5MHz情況(kuang)下(xia)，電(dian)(dian)(dian)(dian)流(liu)在(zai)(zai)近表面的(de)約0.025毫米厚(hou)度(du)中流(liu)動(dong)，而(er)銅(tong)包鋁導(dao)(dao)體(ti)(ti)(ti)(ti)的(de)銅(tong)層(ceng)厚(hou)度(du)比此厚(hou)度(du)多(duo)約一倍。對(dui)于同軸電(dian)(dian)(dian)(dian)纜(lan)，因(yin)為傳輸(shu)的(de)信號是(shi)在(zai)(zai)5MHz以(yi)上(shang)，因(yin)此銅(tong)包鋁導(dao)(dao)體(ti)(ti)(ti)(ti)和純銅(tong)導(dao)(dao)體(ti)(ti)(ti)(ti)傳輸(shu)效果(guo)是(shi)相同的(de)。在(zai)(zai)實際測試電(dian)(dian)(dian)(dian)纜(lan)的(de)衰減可以(yi)證明這一點。
