鍍錫銅線與裸銅絲的區別

銅(tong)(tong)(tong)(tong)線(xian)(xian)的(de)種類有很多種，最常見(jian)的(de)裸(luo)(luo)銅(tong)(tong)(tong)(tong)線(xian)(xian)、鍍(du)錫(xi)銅(tong)(tong)(tong)(tong)線(xian)(xian)和銅(tong)(tong)(tong)(tong)包(bao)鋁線(xian)(xian)，其(qi)中裸(luo)(luo)銅(tong)(tong)(tong)(tong)線(xian)(xian)就是(shi)(shi)(shi)普通的(de)銅(tong)(tong)(tong)(tong)線(xian)(xian)，也稱為(wei)環保銅(tong)(tong)(tong)(tong)線(xian)(xian)，這三種銅(tong)(tong)(tong)(tong)線(xian)(xian)對于(yu)很多人都分不(bu)清楚，尤其(qi)是(shi)(shi)(shi)不(bu)知道裸(luo)(luo)銅(tong)(tong)(tong)(tong)線(xian)(xian)還(huan)是(shi)(shi)(shi)鍍(du)錫(xi)銅(tong)(tong)(tong)(tong)線(xian)(xian)好，那鍍(du)錫(xi)的(de)銅(tong)(tong)(tong)(tong)線(xian)(xian)是(shi)(shi)(shi)否比普通的(de)銅(tong)(tong)(tong)(tong)線(xian)(xian)好呢?

環保裸(luo)銅(tong)(tong)線就是用純銅(tong)(tong)桿拉絲而成的UL1007電(dian)(dian)子線，UL1015電(dian)(dian)子線，UL1061電(dian)(dian)子線，UL1571電(dian)(dian)子線質料(liao)單一，表(biao)里(li)皆銅(tong)(tong)金屬，外(wai)觀看(kan)過去(qu)為顏色(se)(se)，且(qie)因銅(tong)(tong)純度的高(gao)低使顏色(se)(se)有深(shen)有淺。物理性能(neng)上(shang)，裸(luo)銅(tong)(tong)線材質柔軟，導電(dian)(dian)性能(neng)優良。

鍍(du)錫銅(tong)線(xian)(xian)的工藝(yi)比裸(luo)銅(tong)線(xian)(xian)稍稍復(fu)雜些，UL1007，UL1015，UL1061，UL1571，UL1095，UL1430電(dian)子(zi)線(xian)(xian)，UL彩排線(xian)(xian)，UL2651灰排線(xian)(xian)，UL2468，UL端子(zi)線(xian)(xian)，UL導(dao)線(xian)(xian)，UL軟排線(xian)(xian)，PE線(xian)(xian)，UL1332，UL1333，UL3132，UL3135，UL3239，UL1672雙(shuang)層絕緣(yuan)線(xian)(xian)，UL20080軟排線(xian)(xian)，熱宿管(guan)(guan)，鐵氟龍管(guan)(guan)，硅膠管(guan)(guan)，將純銅(tong)桿拉(la)成絲后(hou)再用熱鍍(du)錫工藝(yi)在銅(tong)絲表面鍍(du)上(shang)薄薄的一層錫就成了鍍(du)錫銅(tong)線(xian)(xian)。這種線(xian)(xian)外觀為銀色，因為錫是銀色金屬的緣(yuan)故。

給銅(tong)線(xian)鍍錫主要是為了防止銅(tong)暴露(lu)在空(kong)氣(qi)中(zhong)而(er)被(bei)氧化(hua)形成一(yi)層膜——銅(tong)綠。而(er)銅(tong)綠的導(dao)電性很差，會增加(jia)電阻。可以增加(jia)散熱;可以改(gai)善導(dao)電，改(gai)善導(dao)線(xian)性能(neng)。

另外(wai)，銅(tong)導線鍍(du)錫還(huan)可以防止絕緣橡皮發(fa)粘(zhan)，線芯發(fa)黑變脆，并提高(gao)其可焊性能。

鍍錫銅線(xian)主要用于橡皮(pi)絕緣(yuan)的礦用電(dian)(dian)纜、軟電(dian)(dian)線(xian)、軟電(dian)(dian)纜和船用電(dian)(dian)纜等作(zuo)為導電(dian)(dian)線(xian)芯，以及用作(zuo)電(dian)(dian)纜的外屏蔽編織(zhi)層和電(dian)(dian)刷線(xian)。

鍍錫(xi)(xi)銅(tong)線(xian)(xian)(xian)，材質比較柔軟(ruan)，導(dao)電(dian)性(xing)能良好(hao)，與(yu)裸銅(tong)線(xian)(xian)(xian)相比，其耐蝕性(xing)、抗氧化(hua)性(xing)能更強(qiang)，可大(da)大(da)延長(chang)弱電(dian)線(xian)(xian)(xian)纜(lan)的(de)使用壽命。鍍錫(xi)(xi)銅(tong)線(xian)(xian)(xian)好(hao)用，價格(ge)貴。當然是有(you)涂(tu)層的(de)好(hao)了，而且涂(tu)上的(de)是銀錫(xi)(xi)混(hun)合(he)物，基于涂(tu)層的(de)物理和化(hua)學(xue)特性(xing)，主要功能有(you)二點：

一、表層導(dao)電率(lv)比內(nei)部的(de)銅高,有利于高頻交(jiao)流的(de)集膚效應(ying);

二、由于銀和錫(xi)的(de)化學活(huo)性比銅低(di)，不易氧化生銹，特別(bie)是在高溫潮濕的(de)環境中使(shi)用(yong)(yong)時，優(you)越性相當明顯(xian)，價格也高得多。至于家用(yong)(yong)，實際上這種線(xian)一般適(shi)用(yong)(yong)于大功率高頻電(dian)流的(de)傳輸，在220v50Hz的(de)場合屬于大材小用(yong)(yong)。
