電線在我們日常生活中隨處可見，稍微留意下就會發現，電線有各種各樣的顏色。相信很多人對于電線顏色都不太明白表示什么作用。我們的家庭用電一般都是取自電網三相電，很多人并不知道每根電線的顏色分別代表著什么。今天金環宇電線電纜小編就和大家說說電線的顏色都表示什么意思。

    我們常見的(de)(de)(de)電線顏色(se)有黑、白(bai)、綠、紅、藍(lan)、黃(huang)綠、棕和灰，電線表皮的(de)(de)(de)絕緣護套顏色(se)通常都(dou)(dou)示意著(zhu)有自(zi)己的(de)(de)(de)功(gong)能。所(suo)以，我們在日常的(de)(de)(de)檢修(xiu)與查看用電設備時，除(chu)了(le)關(guan)掉總(zong)開(kai)關(guan)之(zhi)外，還(huan)需(xu)要確(que)定碰到的(de)(de)(de)每(mei)根不同顏色(se)的(de)(de)(de)電線都(dou)(dou)是些什么線。

    一、 各種顏色代表什么線

    根據《住(zhu)宅裝飾(shi)裝修工(gong)程施工(gong)規(gui)范(fan)》GB 50327-2001 16.1.4條規(gui)定：";配線(xian)(xian)(xian)時，相線(xian)(xian)(xian)與零(ling)線(xian)(xian)(xian)的(de)顏色(se)應(ying)不(bu)(bu)同(tong)；同(tong)一(yi)住(zhu)宅相線(xian)(xian)(xian)(L)顏色(se)應(ying)統一(yi)，零(ling)線(xian)(xian)(xian)(N)宜用(yong)藍(lan)色(se)，保(bao)護(hu)線(xian)(xian)(xian)(PE)必須用(yong)黃(huang)綠雙色(se)線(xian)(xian)(xian)"。保(bao)護(hu)線(xian)(xian)(xian)（PE）即地(di)線(xian)(xian)(xian)必須（強(qiang)制性(xing)規(gui)定）用(yong)黃(huang)綠雙色(se)線(xian)(xian)(xian)，零(ling)線(xian)(xian)(xian)用(yong)藍(lan)色(se),（不(bu)(bu)是強(qiang)制性(xing)規(gui)定，在條件(jian)許(xu)可(ke)時，勻應(ying)選擇藍(lan)色(se)線(xian)(xian)(xian)）,三相線(xian)(xian)(xian)不(bu)(bu)使用(yong)藍(lan)色(se)而用(yong)紅、黃(huang)、綠色(se)。

    2、經過變(bian)電(dian)站降(jiang)壓后普通居民(min)供電(dian)線(xian)(xian)路中(zhong)線(xian)(xian)電(dian)壓為380V，相線(xian)(xian)和地線(xian)(xian)或中(zhong)性線(xian)(xian)之間的電(dian)壓(即相電(dian)壓)均為220V。

    小(xiao)區(qu)中(zhong)常見的(de)總(zong)進線(xian)(xian)(xian)是三(san)相(xiang)(xiang)四線(xian)(xian)(xian)制，而我們單個家庭(ting)又采用(yong)單相(xiang)(xiang)接(jie)(jie)法(fa)即(ji)取三(san)個相(xiang)(xiang)線(xian)(xian)(xian)中(zhong)的(de)一相(xiang)(xiang)加中(zhong)性線(xian)(xian)(xian)(作零(ling)線(xian)(xian)(xian))、地(di)線(xian)(xian)(xian)。220V交(jiao)流(liu)電的(de)相(xiang)(xiang)線(xian)(xian)(xian)(火線(xian)(xian)(xian))用(yong)紅色或棕色，因為(wei)這兩種(zhong)顏色是熱(re)色，醒目。使用(yong)零(ling)線(xian)(xian)(xian)時候(hou)那么(me)就可以使用(yong)蘭色或綠色，接(jie)(jie)地(di)線(xian)(xian)(xian)用(yong)黑色或黃(huang)(huang)綠色。 常用(yong)相(xiang)(xiang)線(xian)(xian)(xian)是紅色，零(ling)線(xian)(xian)(xian)藍色，接(jie)(jie)地(di)黑色、黃(huang)(huang)綠色。

    3、直流(liu)電源線：紅色(se)表(biao)示正極，黑色(se)是(shi)負極

    電(dian)源線多采(cai)用多股(gu)線，柔軟性好，方便布局。常采(cai)用RVV2×2.5和RVV2×1.5型號(hao)的電(dian)線。該兩種線分別(bie)代表2芯(xin)2.5平(ping)方毫米和2芯(xin)1.5平(ping)方毫米。可通電(dian)流達10A和6A足夠我們家庭小電(dian)器使(shi)用。
