在常見的絕緣電纜之中，依據構造不一樣可分為單芯和多銅芯電纜，今天，金環宇電線電纜小編詳細介紹的BVV就歸屬于多(duo)銅芯電(dian)(dian)纜，也是(shi)硬電(dian)(dian)導(dao)體構造的護套(tao)線，與(yu)BV絕緣(yuan)電(dian)(dian)纜有什(shen)么不(bu)同呢?
BVV全名銅芯(xin)(PVC)絕緣護(hu)套環形護(hu)套線(xian)，經常用以(yi)暗裝電纜(lan)線(xian)，電器設備(bei)和房屋建筑房間內走(zou)線(xian)。
金環宇BVV電線
1、BVV的線(xian)(xian)指(zhi)的是(shi)銅芯塑(su)膠電(dian)(dian)線(xian)(xian);BV的線(xian)(xian)指(zhi)的是(shi)銅芯聚(ju)乙烯絕緣電(dian)(dian)纜(lan)。BV——裸銅心線(xian)(xian)，常穿管、電(dian)(dian)纜(lan)橋架(jia)鋪設。BVV——護套(tao)線(xian)(xian)，常明敷(fu)。BV線(xian)(xian)通(tong)稱塑(su)銅心線(xian)(xian)，名字為，一般主(zhu)要用途(tu)單芯硬電(dian)(dian)導(dao)體(ti)無護線(xian)(xian)套(tao)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)。B意(yi)味(wei)著是(shi)類型，布電(dian)(dian)纜(lan)線(xian)(xian)，T意(yi)味(wei)著電(dian)(dian)導(dao)體(ti)為：銅電(dian)(dian)導(dao)體(ti)，V意(yi)味(wei)著絕緣層為：聚(ju)乙烯。適用交(jiao)流(liu)電(dian)(dian)流(liu)450/750V及(ji)下(xia)列動力系統、生(sheng)活電(dian)(dian)器(qi)、儀(yi)表盤及(ji)通(tong)訊產品用的電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)。
2、BV是(shi)聚乙(yi)烯絕(jue)緣層單(dan)銅芯(xin)電線，BVV是(shi)多芯(xin)式(shi)護(hu)套(tao)(tao)線,里面是(shi)BV,隨后有(you)兩根(gen)之上(shang)(shang)的芯(xin)再包一層護(hu)線套(tao)(tao),絕(jue)緣層和護(hu)線套(tao)(tao)原材料均為聚乙(yi)烯。BV是(shi)銅心(xin)線上(shang)(shang)立即擠絕(jue)緣層就可以了,而(er)BVV在必須(xu)擠雙(shuang)層護(hu)線套(tao)(tao)，還不可以黏連。
3、軟構(gou)造(zao)(zao)電(dian)導(dao)(dao)(dao)體一般，一般是(shi)一干絞(jiao)線(xian)(xian)電(dian)導(dao)(dao)(dao)體，硬(ying)構(gou)造(zao)(zao)電(dian)導(dao)(dao)(dao)體一般是(shi)單(dan)根電(dian)導(dao)(dao)(dao)體;BVV是(shi)雙絕(jue)緣層(ceng)(ceng)構(gou)造(zao)(zao)，而BV是(shi)單(dan)絕(jue)緣層(ceng)(ceng)構(gou)造(zao)(zao);BVV和BV中間存(cun)有(you)有(you)護線(xian)(xian)套和無護線(xian)(xian)套的(de)(de)差別。根據這兩個規(gui)范(fan)就(jiu)可以(yi)清晰了解他們(men)的(de)(de)差別227IEC01(BV)和227IEC10(BVV)。依照規(gui)范(fan)上規(gui)定(ding)BVV線(xian)(xian)是(shi)2-5芯(xin)，電(dian)導(dao)(dao)(dao)體+絕(jue)緣層(ceng)(ceng)+成(cheng)纜+內護，隨后再擠壓(ya)外護線(xian)(xian)套。BV線(xian)(xian)是(shi)單(dan)銅芯(xin)電(dian)纜，僅有(you)一層(ceng)(ceng)絕(jue)緣層(ceng)(ceng)。
