bv電線和bvr電線之間就相差一個r字母，bv電線是銅芯聚氯乙烯絕緣軟護(hù)套電線，下面就來介紹一下bvr線和bv線的區(qū)別。一、電線代號含義：bv電線是什么？bvr電線是什么？字母B**布電線，字母V**PVC聚氯乙烯，也就是塑料絕緣層。字母R**軟的意思，要做到軟，就是增加導(dǎo)體根數(shù)，減少每根線的直徑。相同面積的所承受的電流不同。內(nèi)芯材料均為。二、電線軟硬程度bv線硬度大于bvr線bv：1根或7根銅絲的單芯線，比較硬，也叫硬線。是家裝布線中**常用的布線型號。bvr：7根或7根以上的銅絲絞合在一起的單芯線，比較軟，也叫軟線。如布線彎道較多，bvr比較方便電工穿管。三、bv線和bvr線的使用環(huán)境這兩種電線之間**主要的區(qū)別就是自身的柔軟程度不同，因此，比較好使用條件也不同。比如說，如果要用于家庭房間內(nèi)的一般穿管配線，那么顯然應(yīng)選用BV線。因?yàn)锽V線導(dǎo)體為單芯，同時具有一定的強(qiáng)度，因此穿線比較方便，同時，因只為單股導(dǎo)體，因此連接時接頭連接比較簡單，且不容易老化。但其缺點(diǎn)也同樣明顯，大家都知道，電流是在電線電纜導(dǎo)體的表面流動，BV系列電線電纜，因只為單股線芯，因此與電流的接觸面積較小，負(fù)荷如果過大容易發(fā)熱，同時，載流量也相對較小。而BVR電線。</p><div
