江蘇電線電纜廠家：硬線和軟線的區別

一、硬線和軟線
硬線的線芯比較粗大，一般型號為BV，比較抗短路電流，容易成型，但穿管比較困難，特別是2.5平方以上的線纜。軟線是由細銅絲組成的，一般型號為BVR，比較軟，不太抗短路電流，難保持固定形狀，就是穿管時比較容易，但成本相對較高。

二、硬導體電線   

單支銅線(xian)較硬，一(yi)般用于(yu)固定敷設場合(如穿管線(xian)路(lu))電流(liu)接觸面積小，負荷大時容易發熱，在線(xian)路(lu)接頭(tou)、設備接線(xian)等(deng)方面較方面價格成本便(bian)宜。

三、軟(ruan)導體電線(xian) 

多股銅線(xian)較軟、不(bu)易折斷線(xian)芯，適用于導線(xian)跟隨運動的(de)場(chang)合(he)(he)，多根導線(xian)敷設(she)在(zai)一起(qi)的(de)場(chang)合(he)(he)，便(bian)于導線(xian)敷設(she)和(he)線(xian)束成型、接觸面積大(da)，散(san)熱快，比較耐用。接線(xian)難度(du)較高(gao)價(jia)格成本(ben)較貴。

四、軟(ruan)線和硬線的(de)用途 

家庭入線(xian)(xian)(xian)槽線(xian)(xian)(xian)管的(de)用(yong)(yong)多股軟(ruan)線(xian)(xian)(xian)，室外或工(gong)地不入槽的(de)用(yong)(yong)單股線(xian)(xian)(xian)。軟(ruan)芯的(de)散熱(re)，導電，抗(kang)拉(la)都處于優(you)勢。用(yong)(yong)硬(ying)芯線(xian)(xian)(xian)穿管的(de)時候(hou)容易破皮，并線(xian)(xian)(xian)時接觸的(de)是點與點。硬(ying)線(xian)(xian)(xian)抗(kang)氧化性能較(jiao)好(hao)，使用(yong)(yong)時間(jian)長(chang);不過在施工(gong)的(de)時候(hou)，如果(guo)電路轉彎過多，多股(軟(ruan)線(xian)(xian)(xian))比較(jiao)好(hao)穿。單線(xian)(xian)(xian)和(he)絞股線(xian)(xian)(xian)同等平(ping)方線(xian)(xian)(xian)經載荷決不一樣(yang)。硬(ying)線(xian)(xian)(xian)，除了1平(ping)方，1.5平(ping)方用(yong)(yong)到(dao)，超過2.5平(ping)方就(jiu)不方便安裝線(xian)(xian)(xian)路了，單股線(xian)(xian)(xian)越大條(tiao)就(jiu)會越是硬(ying)的(de)，容易拉(la)扯線(xian)(xian)(xian)芯和(he)護皮，施工(gong)起來比較(jiao)費(fei)力。軟(ruan)線(xian)(xian)(xian)施工(gong)簡(jian)單，省時省力。

硬線(xian)和軟(ruan)線(xian)的(de)區別  

其中：電(dian)(dian)線(xian)(xian)(xian)(xian)(xian)(xian)常用(yong)的(de)(de)絕緣材料有聚(ju)(ju)氯(lv)乙烯(xi)(xi)和聚(ju)(ju)乙烯(xi)(xi)兩種，聚(ju)(ju)氯(lv)乙烯(xi)(xi)用(yong)“V”表示，聚(ju)(ju)乙烯(xi)(xi)用(yong)“Y”表示1，一(yi)(yi)個硬(ying)(ying)，一(yi)(yi)個軟(ruan)；2，硬(ying)(ying)的(de)(de)是(shi)一(yi)(yi)般(ban)是(shi)里邊是(shi)單(dan)芯(xin)線(xian)(xian)(xian)(xian)(xian)(xian)，就是(shi)導電(dian)(dian)體是(shi)一(yi)(yi)根銅線(xian)(xian)(xian)(xian)(xian)(xian)，軟(ruan)的(de)(de)是(shi)多根銅絲組(zu)成(cheng)的(de)(de)線(xian)(xian)(xian)(xian)(xian)(xian)芯(xin)；3，硬(ying)(ying)線(xian)(xian)(xian)(xian)(xian)(xian)制作(zuo)工藝相對比軟(ruan)線(xian)(xian)(xian)(xian)(xian)(xian)簡(jian)單(dan)；4，高頻(pin)電(dian)(dian)路軟(ruan)線(xian)(xian)(xian)(xian)(xian)(xian)比硬(ying)(ying)線(xian)(xian)(xian)(xian)(xian)(xian)載(zai)流量大，肌膚效應(ying)。5，如果硬(ying)(ying)是(shi)因為帶凱，那硬(ying)(ying)線(xian)(xian)(xian)(xian)(xian)(xian)的(de)(de)機械強度(du)好(hao)于軟(ruan)線(xian)(xian)(xian)(xian)(xian)(xian)，更好(hao)的(de)(de)保(bao)護線(xian)(xian)(xian)(xian)(xian)(xian)纜；6，布線(xian)(xian)(xian)(xian)(xian)(xian)時候有些(xie)地(di)方(fang)(fang)硬(ying)(ying)線(xian)(xian)(xian)(xian)(xian)(xian)容(rong)易布線(xian)(xian)(xian)(xian)(xian)(xian)，有些(xie)地(di)方(fang)(fang)軟(ruan)線(xian)(xian)(xian)(xian)(xian)(xian)容(rong)易布線(xian)(xian)(xian)(xian)(xian)(xian)。硬(ying)(ying)線(xian)(xian)(xian)(xian)(xian)(xian)又叫塑銅線(xian)(xian)(xian)(xian)(xian)(xian)，10平方(fang)(fang)以下(xia)的(de)(de)硬(ying)(ying)線(xian)(xian)(xian)(xian)(xian)(xian)一(yi)(yi)般(ban)都是(shi)單(dan)股(gu)線(xian)(xian)(xian)(xian)(xian)(xian)，家用(yong)電(dian)(dian)線(xian)(xian)(xian)(xian)(xian)(xian)一(yi)(yi)般(ban)不(bu)超過6平方(fang)(fang)。軟(ruan)線(xian)(xian)(xian)(xian)(xian)(xian)又叫護套線(xian)(xian)(xian)(xian)(xian)(xian)，一(yi)(yi)般(ban)是(shi)多股(gu)線(xian)(xian)(xian)(xian)(xian)(xian)，即內部為多股(gu)銅絲纏繞在一(yi)(yi)起。

從制作工藝難度可知，同平方的軟(ruan)線相對于硬線來(lai)說(shuo)，價格較高(gao)。

硬線(xian)(xian)好還是軟(ruan)線(xian)(xian)好？電(dian)氣上“硬線(xian)(xian)”與“軟(ruan)線(xian)(xian)”的(de)(de)概念分別是：硬線(xian)(xian)，直徑1毫米(mi)以上可(ke)(ke)導電(dian)的(de)(de)固態金屬的(de)(de)單根導線(xian)(xian)；軟(ruan)線(xian)(xian)，由多股直徑1毫米(mi)以下可(ke)(ke)導電(dian)的(de)(de)固態金屬絲絞合而成的(de)(de)導線(xian)(xian)。它們各(ge)自(zi)的(de)(de)優缺點可(ke)(ke)從如下幾個方(fang)面考察：

1、橫截面(mian)積。相同載(zai)流量硬線(xian)橫截面(mian)積小，軟線(xian)橫截面(mian)積大；

2、抗拉力。硬(ying)線較強，軟線較弱(ruo)；

3、抗(kang)腐蝕。硬(ying)線(xian)較強，軟線(xian)較弱；

4、抗疲(pi)勞（抗橫向折斷）。硬線(xian)(xian)弱，軟線(xian)(xian)強；

5、絕緣強度。硬(ying)線、軟線都取(qu)決于絕緣層的材料與厚(hou)度；

6、抗“集(ji)膚效應”（即電流(liu)頻率越高，越是趨于導(dao)線表(biao)面，則中(zhong)心部分無電流(liu)，造成浪費）。硬線較差，軟線較好(hao)；

7、廢品回收率（金屬再利(li)用）。硬(ying)線較高，軟(ruan)線較低。

硬線軟線這些各自的優缺點，也決定了各自的應用場所，硬線多用于埋墻、埋地、室外等場所，軟線多用于家電、設備的電源連接線以及電器內部電路板、元件之間的連接。

單(dan)股線(xian)和多股線(xian)的區別

1、相同截(jie)面的單股電(dian)線比多股軟電(dian)線結構簡單，成本低，價(jia)格便宜。軟布電(dian)線價(jia)格要高得多。

2、由(you)于電流的趨(qu)膚效應(ying)，相同(tong)截面的多股電線導電能力比(bi)單股電線導電強。

3、普通布(bu)線一(yi)般用(yong)(yong)(yong)單股(gu)，有特(te)殊要求(qiu)的場合(he)才采(cai)用(yong)(yong)(yong)多股(gu)或者軟布(bu)電線。例如(ru)行(xing)車用(yong)(yong)(yong)布(bu)電線，無論截面大小，均采(cai)用(yong)(yong)(yong)BXR（銅芯(xin)橡(xiang)皮(pi)絕(jue)緣軟電線）。

4、多股或者(zhe)軟布(bu)電線(xian)(xian)比單股電線(xian)(xian)容易(yi)穿電線(xian)(xian)管。這也是行車用軟布(bu)電線(xian)(xian)的原因之一。

根據以上特點，不考慮(lv)昂(ang)貴的(de)造價，只考慮(lv)導電(dian)能力(li)和耐用、安(an)全(quan)等方面，還是多股電(dian)線比(bi)單股電(dian)線要(yao)好得多。

單(dan)股(gu)(gu)電(dian)線(xian)和多(duo)股(gu)(gu)電(dian)線(xian)損耗是差不(bu)多(duo)的，但是相比而言，單(dan)股(gu)(gu)的電(dian)線(xian)比較(jiao)硬(ying)，屬(shu)(shu)硬(ying)線(xian)，多(duo)股(gu)(gu)的電(dian)線(xian)比較(jiao)軟(ruan)，屬(shu)(shu)軟(ruan)線(xian)，比較(jiao)容易彎曲走線(xian)。
