護(hu)線(xian)(xian)(xian)套(tao)(tao)電纜線(xian)(xian)(xian)種(zhong)類一(yi)般分成(cheng)有BVV線(xian)(xian)(xian)和RVV線(xian)(xian)(xian)，在其中他(ta)(ta)們的(de)型號規格英文(wen)字(zi)母(mu)表明B：表明布電纜線(xian)(xian)(xian)，R：意味著銅線(xian)(xian)(xian)軟構(gou)造的(de)含意，V：塑(su)膠(jiao)中的(de)聚乙烯絕緣層，V：塑(su)膠(jiao)中的(de)聚乙烯護(hu)線(xian)(xian)(xian)套(tao)(tao)。實際上這(zhe)二種(zhong)電纜線(xian)(xian)(xian)在其實質上是同樣的(de)，全是歸(gui)屬(shu)于(yu)護(hu)線(xian)(xian)(xian)套(tao)(tao)電纜線(xian)(xian)(xian)，可是開展分別的(de)話，他(ta)(ta)們在類型上和結構(gou)上面有一(yi)定的(de)差別，例如BVV線(xian)(xian)(xian)歸(gui)屬(shu)于(yu)硬護(hu)套(tao)(tao)線(xian)(xian)(xian)，而RVV線(xian)(xian)(xian)歸(gui)屬(shu)于(yu)軟護(hu)套(tao)(tao)線(xian)(xian)(xian)。
以BVV線和RVV線在類型上有哪些不一樣?
BVV電纜線(xian)(xian)全名銅(tong)芯聚乙(yi)烯絕(jue)緣層聚乙(yi)烯護(hu)(hu)線(xian)(xian)套(tao)(tao)圓形護(hu)(hu)套(tao)(tao)線(xian)(xian)，又被稱為輕形聚乙(yi)烯護(hu)(hu)線(xian)(xian)套(tao)(tao)電纜線(xian)(xian)，別名硬護(hu)(hu)套(tao)(tao)線(xian)(xian)，是護(hu)(hu)套(tao)(tao)線(xian)(xian)的一種(zhong)。
RVV電纜全(quan)名(ming)輕形銅芯聚炳(bing)烯(xi)絕緣層聚炳(bing)烯(xi)護(hu)(hu)線(xian)套(tao)軟電纜，又(you)被稱(cheng)為輕形聚乙烯(xi)護(hu)(hu)線(xian)套(tao)銅線(xian),別名(ming)軟護(hu)(hu)套(tao)線(xian)，是護(hu)(hu)套(tao)線(xian)的一種。
二、BVV線和RVV線在結構上有什么(me)不同(tong)?
BVV線(xian)(xian)為內部(bu)單(dan)條(tiao)(tiao)橫截面(mian)很大的(de)銅心線(xian)(xian)，RVV內部(bu)為單(dan)條(tiao)(tiao)橫截面(mian)較小的(de)銅心線(xian)(xian)。比如全(quan)是2*1.5的(de)護(hu)線(xian)(xian)套;
BVV內(nei)芯是單條的銅線(xian)BVV，有兩(liang)個(ge)替芯，每一(yi)(yi)個(ge)替芯的橫截(jie)面是1.5，而(er)每一(yi)(yi)個(ge)內(nei)芯是1根直徑為1.38的銅線(xian);
RVV內芯是(shi)許多(duo)小細條構(gou)成(cheng)的(de),RVV兩個替(ti)(ti)芯，每一個替(ti)(ti)芯的(de)橫截面(mian)是(shi)1.5，可是(shi)每一個內芯是(shi)有30根直徑(jing)為0.25MM的(de)銅線構(gou)成(cheng)。因此BVV比RVV硬;
RVV運(yun)用于家用電器、儀(yi)表盤和電子產品及全自動代設(she)備用電源插頭、控線及數(shu)據信號同軸(zhou)電纜，實際可用以(yi)防(fang)盜(dao)報警(jing)系(xi)統(tong)(tong)系(xi)統(tong)(tong)軟(ruan)件、樓宇對講(jiang)系(xi)統(tong)(tong)系(xi)統(tong)(tong)軟(ruan)件、儀(yi)器設(she)備、儀(yi)表盤、監(jian)控監(jian)管的操(cao)縱安裝等(deng);
BVV硬(ying)護套線(xian)適用(yong)交流電流450/750V及(ji)下列動力系(xi)統、生活電器、儀表盤及(ji)通訊產品用(yong)的電線(xian)電纜，另外還用(yong)以暗裝電纜線(xian)。
