普(pu)(pu)通(tong)(tong)全(quan)(quan)銅(tong)(tong)(tong)網(wang)(wang)線(xian)(xian)(xian)(xian)的(de)(de)(de)含銅(tong)(tong)(tong)量并不是很高。實(shi)際上普(pu)(pu)通(tong)(tong)全(quan)(quan)銅(tong)(tong)(tong)網(wang)(wang)線(xian)(xian)(xian)(xian)導體(ti)主(zhu)要(yao)(yao)材質是青銅(tong)(tong)(tong)。在青銅(tong)(tong)(tong)的(de)(de)(de)外面鍍一層(ceng)無(wu)氧(yang)銅(tong)(tong)(tong)。所以也被叫銅(tong)(tong)(tong)包(bao)銅(tong)(tong)(tong)網(wang)(wang)線(xian)(xian)(xian)(xian)。普(pu)(pu)通(tong)(tong)全(quan)(quan)銅(tong)(tong)(tong)網(wang)(wang)線(xian)(xian)(xian)(xian)在阻值上要(yao)(yao)比(bi)無(wu)氧(yang)銅(tong)(tong)(tong)高很多。大概在110歐姆左右。無(wu)氧(yang)銅(tong)(tong)(tong)網(wang)(wang)線(xian)(xian)(xian)(xian)的(de)(de)(de)精度比(bi)較好，當(dang)數據(ju)在無(wu)氧(yang)銅(tong)(tong)(tong)進行傳輸時，信(xin)號的(de)(de)(de)損耗就(jiu)會(hui)(hui)比(bi)較小。在平常中，我們(men)其(qi)實(shi)很容易(yi)分辨(bian)出全(quan)(quan)銅(tong)(tong)(tong)網(wang)(wang)線(xian)(xian)(xian)(xian)和無(wu)氧(yang)銅(tong)(tong)(tong)網(wang)(wang)線(xian)(xian)(xian)(xian)。因為在市(shi)面上大部分的(de)(de)(de)普(pu)(pu)通(tong)(tong)全(quan)(quan)銅(tong)(tong)(tong)網(wang)(wang)線(xian)(xian)(xian)(xian)內(nei)層(ceng)都(dou)是二料，顏色(se)比(bi)較暗淡。無(wu)氧(yang)銅(tong)(tong)(tong)網(wang)(wang)線(xian)(xian)(xian)(xian)的(de)(de)(de)內(nei)層(ceng)基本(ben)是新料，顏色(se)比(bi)較亮。如果不能用這種(zhong)辦法就(jiu)可以用火燒，普(pu)(pu)通(tong)(tong)全(quan)(quan)銅(tong)(tong)(tong)外層(ceng)迅速融(rong)化，并且發黑無(wu)氧(yang)銅(tong)(tong)(tong)網(wang)(wang)線(xian)(xian)(xian)(xian)只是顏色(se)會(hui)(hui)稍微深，不會(hui)(hui)發黑。或者用刀刮(gua)表層(ceng)，普(pu)(pu)通(tong)(tong)全(quan)(quan)銅(tong)(tong)(tong)的(de)(de)(de)顏色(se)會(hui)(hui)有點(dian)發白，而無(wu)氧(yang)銅(tong)(tong)(tong)則沒(mei)有改變。
