常見的絕緣電纜中，依據構造的不同可分為單層皮電線和雙層皮電線電纜。今天，金環宇電線電纜小編和大家分享下BVV電線與BV單芯絕緣電線的差別?
BVV是一(yi)種(zhong)銅(tong)芯聚(ju)乙烯絕緣護套(tao)的環形護套(tao)線(xian)，常(chang)見于(yu)表層貼(tie)片電纜線(xian)、電器(qi)設備和工程建筑房間內走線(xian)。
1.BVV線(xian)(xian)指(zhi)銅(tong)芯塑膠(jiao)護(hu)套線(xian)(xian);BV線(xian)(xian)指(zhi)銅(tong)芯PVC絕緣電(dian)(dian)纜。BV——裸(luo)銅(tong)心(xin)線(xian)(xian)，常常根(gen)據(ju)管(guan)路(lu)、公路(lu)橋梁鋪設。BVV-硬線(xian)(xian)，常用(yong)(yong)于明(ming)裝。BV線(xian)(xian)通(tong)稱塑膠(jiao)銅(tong)心(xin)線(xian)(xian)，名字為(wei)(wei)通(tong)用(yong)(yong)性單芯硬電(dian)(dian)導(dao)體無護(hu)線(xian)(xian)套電(dian)(dian)線(xian)(xian)電(dian)(dian)纜。b意(yi)(yi)(yi)味著類型，布線(xian)(xian)，T意(yi)(yi)(yi)味著銅(tong)電(dian)(dian)導(dao)體，V意(yi)(yi)(yi)味著PVC絕緣層。適用(yong)(yong)交(jiao)流電(dian)(dian)流為(wei)(wei)450/750伏及下列(lie)的發電(dian)(dian)站、電(dian)(dian)器產品、儀表(biao)設備(bei)和通(tong)訊(xun)產品的電(dian)(dian)纜線(xian)(xian)和電(dian)(dian)纜線(xian)(xian)。
2.BV是(shi)PVC絕緣層的單銅(tong)(tong)芯(xin)電(dian)纜(lan)，BVV是(shi)多(duo)芯(xin)護套(tao)線(xian)，里邊有(you)BV，隨后(hou)有(you)兩(liang)個之上的銅(tong)(tong)芯(xin)電(dian)纜(lan)包(bao)復一層護線(xian)套(tao)。絕緣層和(he)護線(xian)套(tao)原材料是(shi)聚乙烯。BV僅僅立即在(zai)銅(tong)(tong)心線(xian)上擠(ji)絕緣層，而BVV必須擠(ji)雙層護線(xian)套(tao)，可是(shi)不可以(yi)粘。
3.軟構(gou)造電(dian)(dian)導(dao)體(ti)一般是(shi)多芯電(dian)(dian)導(dao)體(ti)，硬構(gou)造電(dian)(dian)導(dao)體(ti)一般是(shi)單根電(dian)(dian)導(dao)體(ti);BVV是(shi)雙皮結(jie)構(gou)，BV是(shi)單層(ceng)(ceng)皮結(jie)構(gou)。根據這兩個規(gui)范(fan)，我們可以清(qing)晰地了解他(ta)們中間的(de)差別:227IEC01(BV)和227IEC10(BVV)。依(yi)照規(gui)范(fan)，BVV線(xian)是(shi)2-5芯，電(dian)(dian)導(dao)體(ti)+絕(jue)(jue)緣(yuan)層(ceng)(ceng)+走線(xian)+內護線(xian)套，隨后外護線(xian)套擠壓。BV線(xian)是(shi)單銅芯電(dian)(dian)纜，僅有一層(ceng)(ceng)絕(jue)(jue)緣(yuan)層(ceng)(ceng)。
