無氧(yang)(yang)(yang)銅(tong)(tong)導(dao)線是(shi)指電線的導(dao)體是(shi)不(bu)(bu)含氧(yang)(yang)(yang)也不(bu)(bu)含任何脫氧(yang)(yang)(yang)劑殘留物的純(chun)銅(tong)(tong)。雖說是(shi)純(chun)銅(tong)(tong)，但基本上難(nan)以避免(mian)含有(you)非常微量氧(yang)(yang)(yang)和(he)一些雜質。按標準規定，銅(tong)(tong)的純(chun)度大(da)于99.95%，氧(yang)(yang)(yang)的含量不(bu)(bu)大(da)于0.003%，雜質總含量不(bu)(bu)大(da)于0.05%即為純(chun)銅(tong)(tong)，也就是(shi)無氧(yang)(yang)(yang)銅(tong)(tong)。

無(wu)(wu)氧(yang)純(chun)(chun)銅(tong)電線(xian)(xian)(xian)當然是(shi)指以(yi)無(wu)(wu)氧(yang)銅(tong)材料為(wei)導(dao)線(xian)(xian)(xian)，由一(yi)根或幾根柔軟(ruan)的(de)導(dao)線(xian)(xian)(xian)組成，外覆一(yi)層輕質護(hu)層。無(wu)(wu)氧(yang)純(chun)(chun)銅(tong)電線(xian)(xian)(xian)是(shi)傳導(dao)電能的(de)載體。無(wu)(wu)氧(yang)純(chun)(chun)銅(tong)線(xian)(xian)(xian)的(de)作(zuo)用是(shi)“傳導(dao)電流”。無(wu)(wu)氧(yang)純(chun)(chun)銅(tong)電線(xian)(xian)(xian)的(de)導(dao)體為(wei)無(wu)(wu)氧(yang)銅(tong)，純(chun)(chun)度高，具有優(you)良的(de)導(dao)電、導(dao)熱、冷熱加工性(xing)能和良好的(de)焊(han)接性(xing)能。
