BVV和BV都屬于硬導體絕緣電線,硬導體結構,方便于敷設時穿管,但柔軟性能不佳,特別是截面積比較大的規格,不利于彎曲,一般用于固定敷設使用。那么,BVV與BV電線有哪些區別呢?金環宇電線電纜小編給(gei)大家(jia)解析一下。
BVV銅(tong)芯(xin)聚氯(lv)乙烯絕緣護(hu)(hu)套(tao)絕緣電(dian)線(xian),家庭用(yong)電(dian)源線(xian),俗稱(cheng)護(hu)(hu)套(tao)線(xian);單芯(xin)時(shi)是圓形(xing)結(jie)構,多芯(xin)時(shi)是扁形(xing)結(jie)構;適(shi)用(yong)于交流電(dian)壓(ya)450/750V及(ji)以下動力裝置、日用(yong)電(dian)器、儀表及(ji)電(dian)信設備(bei)用(yong)的電(dian)纜電(dian)線(xian)。同時(shi)還用(yong)于明裝電(dian)線(xian)。線(xian)芯(xin)長期允許(xu)工作溫度(du)不超過+65度(du)。按照標準要求BVV線(xian)有2-5芯(xin),其標稱(cheng)截面(mian)從0.75-10平方共分(fen)0.75、1.0、1.5、2.5、4、6、10七種規格。
BV銅(tong)芯聚氯乙烯絕緣硬電(dian)線,一般(ban)用途單芯硬導體(ti)無護套電(dian)線;B系列歸屬(shu)布電(dian)線,塑(su)銅(tong)線,適用于電(dian)壓(ya)等級450/750V及以(yi)下動力裝(zhuang)置布線,廣泛應用于家裝(zhuang)布線。常用規(gui)格(ge)包(bao)括1.5、2.5、4、6、10、16、25、35平(ping)方。
BVV與BV電(dian)纜的相(xiang)同點:具有阻(zu)燃、耐(nai)火及低煙(yan)無鹵等特(te)性。
電(dian)線與電(dian)纜的區別
電(dian)(dian)(dian)線(xian)(xian)(xian)與電(dian)(dian)(dian)纜(lan)沒(mei)有嚴格的(de)界限,通常將芯(xin)數(shu)少、產(chan)品(pin)直徑小、結構簡單的(de)產(chan)品(pin)稱(cheng)(cheng)為(wei)(wei)(wei)電(dian)(dian)(dian)線(xian)(xian)(xian),沒(mei)有絕緣(yuan)(yuan)的(de)稱(cheng)(cheng)為(wei)(wei)(wei)裸電(dian)(dian)(dian)線(xian)(xian)(xian),其它(ta)稱(cheng)(cheng)為(wei)(wei)(wei)電(dian)(dian)(dian)纜(lan)。導體截面積較大的(de)(大于6平方毫(hao)米)稱(cheng)(cheng)為(wei)(wei)(wei)大電(dian)(dian)(dian)線(xian)(xian)(xian),較小的(de)(小于或等于6平方毫(hao)米)稱(cheng)(cheng)為(wei)(wei)(wei)小電(dian)(dian)(dian)線(xian)(xian)(xian),絕緣(yuan)(yuan)電(dian)(dian)(dian)線(xian)(xian)(xian)又稱(cheng)(cheng)為(wei)(wei)(wei)布(bu)電(dian)(dian)(dian)線(xian)(xian)(xian)。
