BV电缆(lan)线(xian)：是铜芯聚(ju)氯乙烯绝缘电线(xian)电缆(lan)，简称塑铜线(xian)，是电线(xian)电缆(lan)中(zhong)常用的(de)一种(zhong)线(xian)，也是咱(zan)们日常日子中(zhong)触摸(mo)比(bi)较多的(de)一种(zhong)线(xian)。

bv电线是阻燃的(de)吗？

BV电线和BVV电线一样吗？

差异一：外皮(pi)运用(yong)资(zi)料不同

用打(da)火(huo)(huo)机(ji)烧一(yi)下，BV线外皮大部(bu)分是PVC资料一(yi)点(dian)就焚(fen)烧，而(er)且带(dai)绿色火(huo)(huo)苗灰(hui)渣黑(hei)色气(qi)味冲鼻。ZRBV则不是。

差异二：用处不同

BV线适用于电(dian)器(qi)表(biao)面设备及(ji)动力照明固定布线用，而ZRBV线适用于电(dian)器(qi)表(biao)面设备及(ji)动力照明固定布线用。

差异三：功用不同

阻(zu)(zu)燃(ran)(ran)电线(xian)电缆具有(you)阻(zu)(zu)燃(ran)(ran)特性—为了暂停、削(xue)减(jian)或(huo)抑制资(zi)(zi)(zi)料的(de)焚烧，在资(zi)(zi)(zi)猜中增(zeng)加(jia)一种物质或(huo)对资(zi)(zi)(zi)料来一种处理，通常是在资(zi)(zi)(zi)猜中增(zeng)加(jia)阻(zu)(zu)燃(ran)(ran)剂，使得资(zi)(zi)(zi)料在焚烧时具有(you)阻(zu)(zu)挡或(huo)推迟火焰(yan)延伸(shen)的(de)功用。 而一般BV电线(xian)并没有(you)这一功用。

BVV电线(xian)(xian)全称铜芯(xin)聚(ju)氯乙(yi)烯绝(jue)缘聚(ju)氯乙(yi)烯护套圆(yuan)型护套线(xian)(xian)，又称轻型聚(ju)氯乙(yi)烯护套电缆，俗(su)称硬护套线(xian)(xian)。铜芯(xin)（硬）布电线(xian)(xian)，单芯(xin)的是(shi)圆(yuan)的，双(shuang)芯(xin)的就是(shi)扁的。常常用于明装电线(xian)(xian)。
