金環宇電線電纜小編今天給大家分享關于電源線顏色代表什么？
1、三相(xiang)五(wu)線(xian)(xian)(xian)(xian)(xian)制：電源線(xian)(xian)(xian)(xian)(xian)顏色(se)(se)也是包括交流(liu)電的三個相(xiang)線(xian)(xian)(xian)(xian)(xian)（A、B、C線(xian)(xian)(xian)(xian)(xian)）、中(zhong)性線(xian)(xian)(xian)(xian)(xian)（N線(xian)(xian)(xian)(xian)(xian)）;以及(ji)地線(xian)(xian)(xian)(xian)(xian)（PE線(xian)(xian)(xian)(xian)(xian)）。三相(xiang)五(wu)線(xian)(xian)(xian)(xian)(xian)制標(biao)準導線(xian)(xian)(xian)(xian)(xian)顏色(se)(se)為：A線(xian)(xian)(xian)(xian)(xian)、B線(xian)(xian)(xian)(xian)(xian)藍色(se)(se)（綠色(se)(se)）、C線(xian)(xian)(xian)(xian)(xian)紅色(se)(se)、N線(xian)(xian)(xian)(xian)(xian)褐色(se)(se)，PE線(xian)(xian)(xian)(xian)(xian)黃綠色(se)(se)或黑色(se)(se)。
2、民用(yong)供電(dian)(dian)線(xian)路相(xiang)線(xian)之間的(de)電(dian)(dian)壓(ya)（即線(xian)電(dian)(dian)壓(ya)）為380V，相(xiang)線(xian)和地(di)線(xian)或中(zhong)性線(xian)之間的(de)電(dian)(dian)壓(ya)（即相(xiang)電(dian)(dian)壓(ya)）均(jun)為220V。比(bi)如說(shuo)像進戶線(xian)一(yi)般來(lai)說(shuo)也是要采用(yong)單相(xiang)三(san)線(xian)制，即三(san)個相(xiang)線(xian)中(zhong)的(de)一(yi)相(xiang)加中(zhong)性線(xian)（作(zuo)零線(xian)）、地(di)線(xian)。
220V交(jiao)流(liu)電的相線(xian)（就是火線(xian)）用(yong)紅色(se)(se)或(huo)棕色(se)(se)，因為這兩種顏色(se)(se)是熱(re)色(se)(se)。一(yi)般來說你在用(yong)零線(xian)時候那么(me)就可(ke)以使用(yong)藍色(se)(se)或(huo)綠色(se)(se)，接(jie)地線(xian)用(yong)黑色(se)(se)或(huo)黃綠色(se)(se)相間的。一(yi)般最常用(yong)的是相線(xian)紅色(se)(se),零線(xian)藍色(se)(se),接(jie)地黑色(se)(se)、黃綠色(se)(se)。
3、直流(liu)電源線：紅色表示(shi)正極(ji)，黑色是負極(ji)
一(yi)般家裝(zhuang)電線(xian)用(yong)什么規格？
家庭用(yong)(yong)電(dian)源線(xian)(xian)(xian)宜采用(yong)(yong)RVV2.5和RVV2×1.5型號的(de)電(dian)線(xian)(xian)(xian)。RVV這種也(ye)是標準型號，為銅質護套線(xian)(xian)(xian)RVV2×2.5和RVV2×1.5，分別代(dai)表2芯2.5平(ping)方毫(hao)米(mi)和2芯1.5平(ping)方毫(hao)米(mi)。一般(ban)情況下，RVV2×2.5做主線(xian)(xian)(xian)、干線(xian)(xian)(xian)，RVV2×1.5做單個電(dian)器支線(xian)(xian)(xian)、開關線(xian)(xian)(xian)。單向(xiang)空(kong)調專線(xian)(xian)(xian)用(yong)(yong)RVV2×4，另配專用(yong)(yong)地線(xian)(xian)(xian)。
家(jia)裝中(zhong)使用的(de)電線(xian)一般(ban)(ban)為(wei)單(dan)股銅芯線(xian)，其截面(mian)面(mian)積主(zhu)要有三個規格，分別是4.0mm2，2.5mm2和(he)1.5mm2。另外(wai)還有6.0mm2規格的(de)，主(zhu)要用于進(jin)戶主(zhu)干(gan)線(xian)，家(jia)裝中(zhong)幾乎(hu)不用或(huo)用量(liang)很少，一般(ban)(ban)不列入家(jia)裝電路用線(xian)的(de)范圍。
為了防火(huo)、維修(xiu)和安全，所以你在選(xuan)(xuan)擇家(jia)裝電(dian)線(xian)(xian)規(gui)(gui)格宜選(xuan)(xuan)用(yong)帶標(biao)志的“國標(biao)”銅芯電(dian)線(xian)(xian)，線(xian)(xian)材槽載的面積(ji)一(yi)般是：家(jia)裝電(dian)線(xian)(xian)規(gui)(gui)格照明用(yong)線(xian)(xian)選(xuan)(xuan)用(yong)的是1.5平(ping)(ping)(ping)方毫米，而插座用(yong)線(xian)(xian)選(xuan)(xuan)用(yong)2.5平(ping)(ping)(ping)方毫米，注意空調用(yong)線(xian)(xian)不得小于2.5平(ping)(ping)(ping)方毫米，家(jia)里接(jie)負線(xian)(xian)（零線(xian)(xian)/地線(xian)(xian)）宜選(xuan)(xuan)用(yong)綠黃雙色(se)(se)線(xian)(xian)，而接(jie)開關線(xian)(xian)（火(huo)線(xian)(xian)）則用(yong)紅、黃等任一(yi)種。我(wo)們(men)在同一(yi)家(jia)裝工程中用(yong)線(xian)(xian)的顏色(se)(se)和用(yong)途(tu)要保持一(yi)致。
