RVVB是一種扁型電(dian)源線(xian),柔性構造,和(he)RVV電(dian)源線(xian)事實(shi)上并沒有什么不(bu)同(tong),有的(de)僅僅外(wai)型上的(de)不(bu)一樣(yang),RVV電(dian)源線(xian)是圓形的(de),而RVVB是扁型電(dian)源線(xian)。
RVVB電(dian)源線(xian)(xian)中(zhong),R表明軟電(dian)纜,軟構造的(de)(de),V指的(de)(de)是絕(jue)緣層聚(ju)乙(yi)烯。第二個V指的(de)(de)是聚(ju)乙(yi)烯絕(jue)緣護(hu)套(tao),B指的(de)(de)是平型(xing),扁型(xing)。也就是RVVB電(dian)源線(xian)(xian)是扁型(xing)的(de)(de)護(hu)線(xian)(xian)套(tao)電(dian)源線(xian)(xian)。RVVB一(yi)般只求2芯護(hu)套(tao)線(xian)(xian)、而RVV的(de)(de)電(dian)纜型(xing)號從2-24芯都是有。
RVVB護線(xian)(xian)套電(dian)(dian)(dian)源(yuan)線(xian)(xian)和RVV護線(xian)(xian)套電(dian)(dian)(dian)源(yuan)線(xian)(xian)事實上是相(xiang)同主(zhu)(zhu)要(yao)用途的電(dian)(dian)(dian)源(yuan)線(xian)(xian),是常(chang)見的開關(guan)電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)纜線(xian)(xian)。主(zhu)(zhu)要(yao)差(cha)別(bie)的是在(zai)外觀(guan),RVV電(dian)(dian)(dian)源(yuan)線(xian)(xian)是圓形。
RVVB和RVV電源線(xian)全是多芯(xin)銅(tong)線(xian)絞線(xian)而成(cheng)(cheng),RVV在銷(xiao)售市場上(shang),一般(ban)是擠(ji)(ji)壓(ya)成(cheng)(cheng)型(xing)式(shi)電源線(xian),選用(yong)(yong)擠(ji)(ji)壓(ya)成(cheng)(cheng)型(xing)式(shi)的模貝(bei)擠(ji)(ji)制而成(cheng)(cheng),內部(bu)的間隙是立即用(yong)(yong)PVC添充,一般(ban)結構緊湊、外型(xing)有(you)光澤,不容易毀壞。表皮結實,抗(kang)壓(ya)強度抗(kang)壓(ya)能(neng)力能(neng)比較好(hao)。
而RVVB的截面的護(hu)線(xian)套薄厚(hou)(hou)是(shi)沒有RVV電源(yuan)線(xian)的護(hu)線(xian)套薄厚(hou)(hou)大,抗(kang)(kang)拉性和(he)抗(kang)(kang)壓能力也(ye)沒有RVV電源(yuan)線(xian)好。在挑選RVVB護(hu)線(xian)套時,要更為注意線(xian)纜的構造是(shi)不是(shi)對稱性勻稱,不容易非常容易出現(xian)線(xian)纜開裂、裂開的狀況產生。
更主(zhu)要的(de)(de)一(yi)點超薄處的(de)(de)薄厚(hou)做到一(yi)定的(de)(de)標準(zhun)值,才可以另外確保絕緣層抗壓(ya)強度,不會由于某點的(de)(de)薄厚(hou)較為小而造成 潛在性的(de)(de)安全風(feng)險。
RVV電(dian)(dian)源(yuan)(yuan)線(xian)和(he)RVVB電(dian)(dian)源(yuan)(yuan)線(xian)用以監管,家庭裝(zhuang),工(gong)程項目家用電(dian)(dian)器(qi)中小型專用工(gong)具(ju)等,RVVB電(dian)(dian)源(yuan)(yuan)線(xian)在一定水平上比(bi)RVV電(dian)(dian)源(yuan)(yuan)線(xian)節(jie)約室內(nei)空間。
挑選電(dian)源線時,提議采用無氧(yang)銅(tong)電(dian)源線,電(dian)阻器低,傳送效果非常的好。
