電線電纜中有(you)(you)(you)(you)單芯和(he)(he)(he)多芯之分,會有(you)(you)(you)(you)不了(le)解的用(yong)戶有(you)(you)(you)(you)疑(yi)問,3+2芯和(he)(he)(he)4+1芯,看(kan)著都是5芯,那(nei)這兩(liang)者到底有(you)(you)(you)(you)沒有(you)(you)(you)(you)區別呢?下面華強電(dian)纜(lan)小編來介紹(shao)下電(dian)線電(dian)纜(lan)3+2和(he)(he)(he)4+1芯的含義及(ji)區別.

一、電線和(he)電纜的區別

電線(xian)是(shi)由一根或幾(ji)根柔軟的導(dao)線(xian)組成(cheng),外面包以(yi)輕軟的護層;

電纜是由一根或幾根絕緣包導線組成,外面再包以金屬或橡皮制的堅韌外層.

二(er)、電線上的3+2和(he)4+1表示一根電纜(lan)線的芯(xin)(xin)(xin)數,一根電纜(lan)里面(mian)有相互絕(jue)緣的2條(tiao)或3條(tiao)、3+2條(tiao)、4+1條(tiao)線、5條(tiao)線,分別叫2芯(xin)(xin)(xin)或3芯(xin)(xin)(xin)、3+2芯(xin)(xin)(xin)、4+1芯(xin)(xin)(xin)、5等芯(xin)(xin)(xin)線.

三、下面以電力電纜YJV為例

YJV 3+2芯(xin)

3+2電纜的(de)3就(jiu)是三根相(xiang)線(xian)(xian)(xian)(xian)(L1,L2,L3相(xiang)線(xian)(xian)(xian)(xian),這三條(tiao)(tiao)(tiao)線(xian)(xian)(xian)(xian)直(zhi)徑(jing)最大(da))線(xian)(xian)(xian)(xian)的(de)直(zhi)徑(jing)一樣(yang)大(da),2就(jiu)是零線(xian)(xian)(xian)(xian)和(he)和(he)PE線(xian)(xian)(xian)(xian),一條(tiao)(tiao)(tiao)線(xian)(xian)(xian)(xian)用(yong)于(yu)接零線(xian)(xian)(xian)(xian)(N中性線(xian)(xian)(xian)(xian),這條(tiao)(tiao)(tiao)直(zhi)徑(jing)相(xiang)對(dui)L1,L2,L3小(xiao))、一條(tiao)(tiao)(tiao)線(xian)(xian)(xian)(xian)用(yong)于(yu)接接地線(xian)(xian)(xian)(xian)(PE接地保護線(xian)(xian)(xian)(xian),這條(tiao)(tiao)(tiao)直(zhi)徑(jing)相(xiang)對(dui)L1,L2,L3也小(xiao)).

四、YJV 4+1芯(xin)

4+1電纜的4就(jiu)是三根相線(xian)(xian)(xian)和零線(xian)(xian)(xian)的直(zhi)徑一(yi)樣大,1就(jiu)是PE接(jie)地線(xian)(xian)(xian)單獨是一(yi)個直(zhi)徑;4+1 就(jiu)是一(yi)條(tiao)(tiao)電纜由4條(tiao)(tiao)線(xian)(xian)(xian),其中一(yi)條(tiao)(tiao)線(xian)(xian)(xian)用(yong)于接(jie)火線(xian)(xian)(xian)(L1相線(xian)(xian)(xian)),一(yi)條(tiao)(tiao)線(xian)(xian)(xian)用(yong)于接(jie)零線(xian)(xian)(xian)(N中性線(xian)(xian)(xian)),一(yi)條(tiao)(tiao)線(xian)(xian)(xian)用(yong)于接(jie)接(jie)地線(xian)(xian)(xian)(PE接(jie)地保(bao)護(hu)線(xian)(xian)(xian))也行
