電線電纜分單芯和多芯電纜線，其中多芯電纜線包含2芯、3芯、4芯、5芯;依據構造不一樣，5芯電纜線分成3+2芯和4+1芯;那么，全是5芯電纜線，二者有什么不一樣呢?和金環宇電線電纜小編一起來看看吧!
一、電線和電纜(lan)的差別(bie)
電(dian)線是由一根(gen)或(huo)二根(gen)綿軟的(de)(de)電(dian)纜線構成，外切片面(mian)包以(yi)軟柔的(de)(de)護層(ceng);
電纜(lan)是(shi)由(you)一根或二根絕緣套管包電纜(lan)線構成，外邊(bian)再(zai)包以金屬材(cai)料(liao)高分子材(cai)料(liao)表層。
二、五芯電(dian)纜3+2和(he)4+1的差別
五(wu)芯電(dian)纜(lan)(lan)(lan)上的3+2和(he)4+1表(biao)明(ming)一根(gen)電(dian)纜(lan)(lan)(lan)的電(dian)纜(lan)(lan)(lan)型號，一根(gen)電(dian)纜(lan)(lan)(lan)線里邊(bian)有彼此之間絕緣套(tao)管的2條或(huo)3條、3+2條、4+1條線、5根(gen)線，各(ge)自叫2芯或(huo)3芯、3+2芯、4+1芯、5等銅芯電(dian)纜(lan)(lan)(lan)。下邊(bian)以電(dian)纜(lan)(lan)(lan)YJV為(wei)例證：
3+2芯電纜(lan)線(xian)
YJV3+2芯
3+2電(dian)纜線(xian)(xian)(xian)(xian)的(de)3便(bian)是三根(gen)火線(xian)(xian)(xian)(xian)零(ling)(ling)線(xian)(xian)(xian)(xian)(L1，L2，L3火線(xian)(xian)(xian)(xian)零(ling)(ling)線(xian)(xian)(xian)(xian)，這三條線(xian)(xian)(xian)(xian)直徑非(fei)常大)線(xian)(xian)(xian)(xian)的(de)直徑一樣(yang)大，2便(bian)是零(ling)(ling)線(xian)(xian)(xian)(xian)和(he)和(he)PE線(xian)(xian)(xian)(xian)，一條線(xian)(xian)(xian)(xian)用以接零(ling)(ling)線(xian)(xian)(xian)(xian)(N中性點，這一條直徑相對(dui)(dui)性L1，L2，L3小(xiao))、一條線(xian)(xian)(xian)(xian)用以接布線(xian)(xian)(xian)(xian)頭(PE維護保(bao)養接線(xian)(xian)(xian)(xian)頭，這一條直徑相對(dui)(dui)性L1，L2，L3也(ye)小(xiao))。
4+1芯(xin)電纜線
YJV4+1芯
4+1電纜(lan)線(xian)的4便(bian)是三根火(huo)(huo)線(xian)零線(xian)和(he)零線(xian)的直徑一(yi)(yi)樣(yang)大，1便(bian)是PE布線(xian)頭(tou)(tou)獨立是一(yi)(yi)個直徑;4+1便(bian)是一(yi)(yi)條(tiao)(tiao)電纜(lan)線(xian)由4根線(xian)，在(zai)這里在(zai)其中一(yi)(yi)條(tiao)(tiao)線(xian)用(yong)(yong)以(yi)(yi)接(jie)火(huo)(huo)線(xian)零線(xian)(L1火(huo)(huo)線(xian)零線(xian))，一(yi)(yi)條(tiao)(tiao)線(xian)用(yong)(yong)以(yi)(yi)接(jie)零線(xian)(N中性點)，一(yi)(yi)條(tiao)(tiao)線(xian)用(yong)(yong)以(yi)(yi)接(jie)布線(xian)頭(tou)(tou)(PE維護保養接(jie)線(xian)頭(tou)(tou))也行(xing)。
