電線電纜顏色和數字

電纜電線數字代表的是電纜電線的規格型號，每個電纜字母的數字都是有特殊含義的，我們在看電纜線規格的時候，一定要看清楚電纜線規格型號的數字。電線之所以要分顏色最主要的原因就是為了用電安全，避免接線時出現接錯的情況，讓我們可以更好的分清各個線路的位置，降低誤操作幾率提高接線的安全性，同時，也是為了方便各個家庭日后的電路維修，讓維修人員能在短時間內就能找到故障部位，以便及時維修。

電線電纜顏色區分

電(dian)(dian)線(xian)(xian)(xian)(xian)(xian)(xian)顏色(se)(se)(se)黑(hei)、白(bai)、綠、紅(hong)(hong)、藍(lan)、橙、棕和灰，電(dian)(dian)線(xian)(xian)(xian)(xian)(xian)(xian)外面(mian)的(de)(de)(de)絕緣護(hu)套顏色(se)(se)(se)通常都有自(zi)己的(de)(de)(de)指代意(yi)義；藍(lan)色(se)(se)(se)線(xian)(xian)(xian)(xian)(xian)(xian)代表(biao)(biao)零線(xian)(xian)(xian)(xian)(xian)(xian)，黃(huang)色(se)(se)(se)、綠色(se)(se)(se)、紅(hong)(hong)色(se)(se)(se)線(xian)(xian)(xian)(xian)(xian)(xian)通常代表(biao)(biao)三(san)相線(xian)(xian)(xian)(xian)(xian)(xian)的(de)(de)(de)u、v、w相即火線(xian)(xian)(xian)(xian)(xian)(xian)，黃(huang)綠雙色(se)(se)(se)線(xian)(xian)(xian)(xian)(xian)(xian)代表(biao)(biao)保護(hu)接地(di)線(xian)(xian)(xian)(xian)(xian)(xian)。還有，白(bai)色(se)(se)(se)很(hen)少用，黑(hei)色(se)(se)(se)都在電(dian)(dian)氣設(she)備箱、柜內的(de)(de)(de)連接線(xian)(xian)(xian)(xian)(xian)(xian)。紅(hong)(hong)色(se)(se)(se)是(shi)火線(xian)(xian)(xian)(xian)(xian)(xian)，藍(lan)色(se)(se)(se)是(shi)零線(xian)(xian)(xian)(xian)(xian)(xian)，黃(huang)色(se)(se)(se)或黃(huang)白(bai)相間的(de)(de)(de)是(shi)地(di)線(xian)(xian)(xian)(xian)(xian)(xian)最(zui)常用的(de)(de)(de)；黃(huang)色(se)(se)(se)、綠色(se)(se)(se)、紅(hong)(hong)色(se)(se)(se)代表(biao)(biao)相線(xian)(xian)(xian)(xian)(xian)(xian)。也(ye)可(ke)以說是(shi)火線(xian)(xian)(xian)(xian)(xian)(xian)這(zhe)種線(xian)(xian)(xian)(xian)(xian)(xian)都帶(dai)電(dian)(dian)的(de)(de)(de)。藍(lan)色(se)(se)(se)代表(biao)(biao)工作(zuo)零，也(ye)可(ke)以說零線(xian)(xian)(xian)(xian)(xian)(xian)，這(zhe)根(gen)線(xian)(xian)(xian)(xian)(xian)(xian)一般不帶(dai)電(dian)(dian)的(de)(de)(de)，但也(ye)有帶(dai)電(dian)(dian)的(de)(de)(de)時(shi)候。那就(jiu)(jiu)是(shi)零線(xian)(xian)(xian)(xian)(xian)(xian)斷(duan)了時(shi)這(zhe)根(gen)線(xian)(xian)(xian)(xian)(xian)(xian)就(jiu)(jiu)帶(dai)電(dian)(dian)了，雙色(se)(se)(se)代表(biao)(biao)地(di)線(xian)(xian)(xian)(xian)(xian)(xian)，這(zhe)根(gen)線(xian)(xian)(xian)(xian)(xian)(xian)是(shi)最(zui)安全(quan)的(de)(de)(de)，這(zhe)根(gen)線(xian)(xian)(xian)(xian)(xian)(xian)的(de)(de)(de)作(zuo)用就(jiu)(jiu)是(shi)零線(xian)(xian)(xian)(xian)(xian)(xian)斷(duan)后(hou)電(dian)(dian)人(ren)，幫助漏電(dian)(dian)跳閘的(de)(de)(de)。
