軟銅絞線是做什么的：
軟(ruan)銅(tong)(tong)絞(jiao)線(xian)適用(yong)于(yu)電(dian)(dian)(dian)氣裝備、電(dian)(dian)(dian)子(zi)電(dian)(dian)(dian)器(qi)或(huo)元(yuan)件接線(xian)或(huo)這些場(chang)合用(yong)軟(ruan)結構緣電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的導體線(xian)芯。軟(ruan)銅(tong)(tong)絞(jiao)線(xian)是輸配(pei)電(dian)(dian)(dian)用(yong)電(dian)(dian)(dian)氣裝置(如(ru)變壓器(qi)、電(dian)(dian)(dian)爐)及電(dian)(dian)(dian)子(zi)電(dian)(dian)(dian)器(qi)設備、可控硅(gui)元(yuan)件的軟(ruan)連接線(xian)。軟(ruan)銅(tong)(tong)絞(jiao)線(xian)采用(yong)圓銅(tong)(tong)線(xian)或(huo)鍍(du)錫軟(ruan)圓銅(tong)(tong)線(xian)制成(cheng)。加工過(guo)程中經韌煉處(chu)理，使(shi)成(cheng)品柔軟(ruan)、外表(biao)整齊美觀(guan)。

軟(ruan)銅(tong)絞(jiao)線的基本(ben)工(gong)序流程：銅(tong)桿→銅(tong)桿檢(jian)驗(yan)(按gb/t電工(gong)用銅(tong)線胚(pei))→拉(la)絲(大拉(la)機)→中、小拉(la)(連續(xu)退(tui)(tui)火或罐式退(tui)(tui)火)→絞(jiao)股(管(guan)絞(jiao)機或束線機)→導體(ti)絞(jiao)合(管(guan)絞(jiao)機、籠絞(jiao)機，要求退(tui)(tui)扭)→成品檢(jian)驗(yan)(按標(biao)準gb12970.→包裝→入庫。

軟(ruan)銅絞(jiao)線是電(dian)氣(qi)裝備(bei)及電(dian)子電(dian)器(qi)或元件接線用(yong)的軟(ruan)連(lian)接線。軟(ruan)銅絞(jiao)線的主要(yao)的產品標(biao)準按{gb∕t 12970.電(dian)工軟(ruan)銅絞(jiao)線 第2部分：軟(ruan)銅絞(jiao)線。

鍍錫(xi)軟銅(tong)絞(jiao)線基本工藝流程：銅(tong)桿→銅(tong)桿檢驗(按gb/t《電(dian)工用銅(tong)線胚》)→拉絲(大(da)拉機(ji))→鍍錫(xi)(電(dian)解(jie)鍍錫(xi)機(ji))→中、小(xiao)拉(連續退火)→熱鍍錫(xi)(此工序是沒(mei)有電(dian)解(jie)鍍錫(xi)機(ji)時)→絞(jiao)股(管絞(jiao)機(ji)或(huo)束線機(ji))→導體絞(jiao)合(管絞(jiao)機(ji)、籠(long)絞(jiao)機(ji)，要求退扭)→成品檢驗(按標準(zhun)gb12970.→包裝→入庫。

軟銅絞線(xian)的直流電(dian)阻(zu)率(20°c)不大(da)于0.0182ω.mm^2/m ;鍍錫軟銅絞線(xian)的直流電(dian)阻(zu)率(20°c)不大(da)于0.0193ω.mm^2/m。

需要仔細的(de)(de)(de)觀察檢驗鎂(mei)(mei)銅(tong)鎂(mei)(mei)合(he)(he)金線(xian)(xian)的(de)(de)(de)質(zhi)量，不(bu)(bu)能(neng)選擇不(bu)(bu)合(he)(he)格(ge)的(de)(de)(de)產品用來生產電(dian)線(xian)(xian)和電(dian)纜，會(hui)造成嚴重的(de)(de)(de)事故。 然(ran)后看鎂(mei)(mei)銅(tong)鎂(mei)(mei)合(he)(he)金線(xian)(xian)焊(han)(han)(han)接(jie)(jie)(jie)工藝 鎂(mei)(mei)銅(tong)鎂(mei)(mei)合(he)(he)金線(xian)(xian)的(de)(de)(de)選購(gou)還要注意焊(han)(han)(han)接(jie)(jie)(jie)的(de)(de)(de)工藝是否牢靠(kao)，焊(han)(han)(han)接(jie)(jie)(jie)的(de)(de)(de)接(jie)(jie)(jie)口(kou)部分是否整(zheng)齊，有役有線(xian)(xian)條的(de)(de)(de)不(bu)(bu)平整(zheng)現象。焊(han)(han)(han)接(jie)(jie)(jie)的(de)(de)(de)接(jie)(jie)(jie)口(kou)應該(gai)維修(xiu)整(zheng)齊，修(xiu)平整(zheng)，搓圓，不(bu)(bu)能(neng)扎手，焊(han)(han)(han)頭的(de)(de)(de)直徑一般不(bu)(bu)能(neng)過點二毫米;相(xiang)鄰(lin)兩個鎂(mei)(mei)銅(tong)鎂(mei)(mei)合(he)(he)金線(xian)(xian)的(de)(de)(de)焊(han)(han)(han)接(jie)(jie)(jie)應該(gai)保(bao)持距離(li)，I司(si)隔要均(jun)勻。
