護套線-來賓UL護套線-柳州UL護套線

護(hu)套(tao)(tao)線(xian)(xian)其實可以理解為(wei)兩(liang)根(gen)(gen)或(huo)者三根(gen)(gen)并(bing)列平行的(de)(de)BV電(dian)線(xian)(xian)（這里指的(de)(de)是(shi)BVV護(hu)套(tao)(tao)線(xian)(xian)），BV電(dian)線(xian)(xian)本來有(you)絕(jue)緣(yuan)膠(jiao)皮的(de)(de)，在三根(gen)(gen)或(huo)者兩(liang)根(gen)(gen)并(bing)列平行的(de)(de)BV線(xian)(xian)外面再裹(guo)一層膠(jiao)皮這層膠(jiao)皮就是(shi)護(hu)套(tao)(tao)線(xian)(xian)。護(hu)套(tao)(tao)線(xian)(xian)也是(shi)一種(zhong)常用的(de)(de)家用電(dian)線(xian)(xian)，通常是(shi)由(you)三芯(xin)或(huo)者兩(liang)芯(xin)組成的(de)(de)。從(cong)材(cai)質上(shang)分(fen)(fen)，護(hu)套(tao)(tao)線(xian)(xian)可分(fen)(fen)為(wei)軟護(hu)套(tao)(tao)(rvv)和硬(ying)護(hu)套(tao)(tao)(bvv)。軟護(hu)套(tao)(tao)是(shi)儀表電(dian)器系統中比較常用的(de)(de)一種(zhong)類型，內部的(de)(de)芯(xin)線(xian)(xian)根(gen)(gen)數(shu)不定，外面還(huan)有(you)PVC護(hu)套(tao)(tao)，而且對芯(xin)線(xian)(xian)之間(jian)的(de)(de)排(pai)列沒有(you)特別要求。硬(ying)護(hu)套(tao)(tao)線(xian)(xian)可以用于(yu)動力裝(zhuang)置、儀表、電(dian)信(xin)設備及生活(huo)電(dian)器等交流(liu)電(dian)壓在450/750V及以下(xia)用的(de)(de)電(dian)纜(lan)電(dian)線(xian)(xian)，同時還(huan)用于(yu)明裝(zhuang)電(dian)線(xian)(xian)。

由于現在家庭的裝修，一般都用線管，然后用三根銅線(火線、零線、接地線)穿過線管敷設。但護套線要比普通電線安全得多，所以現在在建筑領域家庭裝修中還是用得多。護套線就是以前用的電源線，以前家庭裝修，都用護套線作為照明和電源線；它可以直接埋設在墻內或是固定在墻上。它的好處在于可以省去穿線管或者穿線槽，由外邊的一層護套絕緣代替，敷設方便，快捷，外觀好看，使用安全，是連接家用移動插板，冰箱或者空調等電器的選擇。

護套線(xian)是兩(liang)根或(huo)者三根并(bing)列平行的BV電線(xian)，一(yi)(yi)般(ban)具有(you)絕緣性(xing)能(neng)，護線(xian)套也是家用電線(xian)的一(yi)(yi)種，然而(er)對(dui)于電纜線(xian)通(tong)常(chang)是由幾根或(huo)幾組(zu)導線(xian)每組(zu)至(zhi)少兩(liang)根絞合而(er)成的類似繩索的電纜，每組(zu)導線(xian)之(zhi)間相互絕緣，并(bing)常(chang)圍繞著一(yi)(yi)根中心扭成，整個外面包有(you)高度絕緣的覆蓋層。多架(jia)設在空(kong)中或(huo)裝(zhuang)在地(di)下(xia)、水底，用于電訊或(huo)電力(li)輸送。

生(sheng)活中RVV軟護套線(xian)(xian)，可(ke)謂是隨處可(ke)見(jian)。比如(ru)插座線(xian)(xian)，燈頭線(xian)(xian)等(deng)等(deng)。隨著現代家裝電(dian)(dian)器的(de)增多(duo)，如(ru)電(dian)(dian)視(shi)，冰(bing)箱，電(dian)(dian)腦等(deng)等(deng)，家用電(dian)(dian)線(xian)(xian)的(de)種類也(ye)越來(lai)越多(duo)。電(dian)(dian)線(xian)(xian)鋪設在(zai)外面(mian)不美(mei)觀，而(er)且不安(an)(an)全。安(an)(an)裝在(zai)墻(qiang)內(nei)，不方便。于(yu)是，護套線(xian)(xian)應運(yun)而(er)生(sheng)。它比普通線(xian)(xian)較安(an)(an)全，多(duo)一層保護套，可(ke)以直接埋設在(zai)墻(qiang)內(nei)或固定在(zai)墻(qiang)上，好處在(zai)于(yu)可(ke)以省去穿(chuan)線(xian)(xian)管(guan)或者穿(chuan)線(xian)(xian)槽。敷設方便快捷簡單，且外觀形態優美(mei)，聚(ju)氯乙烯絕緣外套有耐(nai)磨耐(nai)酸堿、耐(nai)油、防火、抗凍，使用壽命長等(deng)特(te)點。

RVV電線全稱銅芯聚氯乙烯絕緣聚氯乙烯護套軟電線，又稱輕型聚氯乙烯護套軟線,俗稱軟護套線，是護套線的一種。主要應用于電器、儀表和電子設備及自動化裝置用電源線、控制線及信號傳輸線，具體可用于防盜報警系統、樓宇對講系統等。
