裸(luo)(luo)銅(tong)(tong)線就是用純(chun)(chun)銅(tong)(tong)桿拉絲而成的銅(tong)(tong)線，質(zhi)料單一(yi)，表里皆銅(tong)(tong)金屬，外觀看(kan)過去為(wei)黃色，且因銅(tong)(tong)純(chun)(chun)度的高低(di)使(shi)顏色有深有淺。物(wu)理性能上，裸(luo)(luo)銅(tong)(tong)線材質(zhi)柔軟(ruan)，導電性能優良。 

鍍錫銅(tong)(tong)(tong)線(xian)的(de)工(gong)藝(yi)比裸(luo)銅(tong)(tong)(tong)線(xian)稍稍復(fu)雜些,UL1007，UL1015，UL1061，UL1571，UL1095，UL1430電子(zi)線(xian)，UL彩排線(xian)，UL2651灰排線(xian)，UL2468，UL端(duan)子(zi)線(xian)，UL導線(xian)，UL軟(ruan)排線(xian)，PE線(xian)，UL1332，UL1333，UL3132，UL3135，UL3239，UL1672雙層絕(jue)緣線(xian),UL20080軟(ruan)排線(xian),熱(re)宿管(guan)，鐵氟龍(long)管(guan)，硅(gui)膠管(guan) 將純銅(tong)(tong)(tong)桿拉成(cheng)(cheng)絲后再用(yong)熱(re)鍍錫工(gong)藝(yi)在銅(tong)(tong)(tong)絲表面鍍上薄(bo)薄(bo)的(de)一層錫就成(cheng)(cheng)了鍍錫銅(tong)(tong)(tong)線(xian)。這種(zhong)線(xian)外觀為(wei)銀色(se)(se)，因為(wei)錫是銀色(se)(se)金屬的(de)緣故。鍍錫銅(tong)(tong)(tong)線(xian)，材質比較(jiao)柔軟(ruan)，導電性(xing)能良(liang)好，與裸(luo)銅(tong)(tong)(tong)線(xian)相比，其(qi)耐蝕性(xing)、抗氧化(hua)性(xing)能更強，可大大延長(chang)弱電線(xian)纜的(de)使(shi)用(yong)壽命。
