護套線-奉節UL護套線-開縣UL護套線。

護(hu)(hu)套(tao)線(xian)(xian)(xian)(xian)其實(shi)可以(yi)理解為兩(liang)根(gen)(gen)或(huo)者三根(gen)(gen)并列平(ping)行的(de)(de)(de)BV電(dian)(dian)(dian)線(xian)(xian)(xian)(xian)（這里指(zhi)的(de)(de)(de)是(shi)BVV護(hu)(hu)套(tao)線(xian)(xian)(xian)(xian)），BV電(dian)(dian)(dian)線(xian)(xian)(xian)(xian)本來有(you)(you)絕(jue)緣膠(jiao)皮(pi)的(de)(de)(de)，在(zai)三根(gen)(gen)或(huo)者兩(liang)根(gen)(gen)并列平(ping)行的(de)(de)(de)BV線(xian)(xian)(xian)(xian)外面再裹(guo)一層膠(jiao)皮(pi)這層膠(jiao)皮(pi)就是(shi)護(hu)(hu)套(tao)線(xian)(xian)(xian)(xian)。護(hu)(hu)套(tao)線(xian)(xian)(xian)(xian)也(ye)是(shi)一種常用(yong)(yong)的(de)(de)(de)家(jia)用(yong)(yong)電(dian)(dian)(dian)線(xian)(xian)(xian)(xian)，通常是(shi)由三芯或(huo)者兩(liang)芯組成(cheng)的(de)(de)(de)。從材質上分(fen)，護(hu)(hu)套(tao)線(xian)(xian)(xian)(xian)可分(fen)為軟護(hu)(hu)套(tao)(rvv)和硬護(hu)(hu)套(tao)(bvv)。軟護(hu)(hu)套(tao)是(shi)儀表電(dian)(dian)(dian)器系統中(zhong)比較(jiao)常用(yong)(yong)的(de)(de)(de)一種類(lei)型，內部的(de)(de)(de)芯線(xian)(xian)(xian)(xian)根(gen)(gen)數不定(ding)，外面還(huan)有(you)(you)PVC護(hu)(hu)套(tao)，而且對芯線(xian)(xian)(xian)(xian)之間的(de)(de)(de)排(pai)列沒有(you)(you)特別要求(qiu)。硬護(hu)(hu)套(tao)線(xian)(xian)(xian)(xian)可以(yi)用(yong)(yong)于動力裝置、儀表、電(dian)(dian)(dian)信設備及生活(huo)電(dian)(dian)(dian)器等交流電(dian)(dian)(dian)壓在(zai)450/750V及以(yi)下用(yong)(yong)的(de)(de)(de)電(dian)(dian)(dian)纜電(dian)(dian)(dian)線(xian)(xian)(xian)(xian)，同時還(huan)用(yong)(yong)于明裝電(dian)(dian)(dian)線(xian)(xian)(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(shi)(shi)兩根(gen)(gen)或(huo)(huo)(huo)者三(san)根(gen)(gen)并列平行的(de)(de)BV電(dian)(dian)線(xian)，一般具有絕(jue)緣(yuan)(yuan)性能(neng)，護線(xian)套也(ye)是(shi)(shi)家用電(dian)(dian)線(xian)的(de)(de)一種，然(ran)而(er)對于電(dian)(dian)纜線(xian)通常(chang)是(shi)(shi)由幾根(gen)(gen)或(huo)(huo)(huo)幾組導線(xian)每(mei)組至少兩根(gen)(gen)絞合而(er)成的(de)(de)類似(si)繩索的(de)(de)電(dian)(dian)纜，每(mei)組導線(xian)之間相互絕(jue)緣(yuan)(yuan)，并常(chang)圍繞著一根(gen)(gen)中心扭(niu)成，整個外面包有高(gao)度絕(jue)緣(yuan)(yuan)的(de)(de)覆蓋層。多架設(she)在(zai)空中或(huo)(huo)(huo)裝(zhuang)在(zai)地下、水底，用于電(dian)(dian)訊(xun)或(huo)(huo)(huo)電(dian)(dian)力輸送。

裝(zhuang)修(xiu)會(hui)涉及到(dao)材(cai)料(liao)的購(gou)買，在購(gou)買電線(xian)(xian)的時候很多商家會(hui)欺騙您外(wai)行不懂，就拿(na)殘次品來忽悠人。那么如何判斷電線(xian)(xian)是否合格呢，下面小編來告訴你(ni)。現在家庭(ting)的裝(zhuang)修(xiu)，一般都(dou)用線(xian)(xian)管，然后用三根(gen)銅(tong)線(xian)(xian)（火線(xian)(xian)、零線(xian)(xian)、接地線(xian)(xian)）穿過線(xian)(xian)管鋪設。但護(hu)套線(xian)(xian)要比普通電線(xian)(xian)安全得多，所以(yi)現在在建筑領(ling)域家庭(ting)裝(zhuang)修(xiu)中還是多有用到(dao)。護(hu)套線(xian)(xian)已然成為家裝(zhuang)界的主力軍。

選擇電線電纜首先要看的是外觀，一般色澤均勻、光滑圓潤、絕緣皮和銅芯不易被剝離的就是合格的。

這(zhe)里要(yao)提醒大家(jia)：有的(de)(de)(de)劣(lie)質電(dian)(dian)(dian)(dian)線(xian)外(wai)(wai)皮(pi)看(kan)(kan)著(zhu)厚，但是(shi)(shi)用力擠壓(ya)的(de)(de)(de)時候，會出現白色。這(zhe)樣的(de)(de)(de)電(dian)(dian)(dian)(dian)線(xian)比較容易老化漏電(dian)(dian)(dian)(dian)。除(chu)了上面說的(de)(de)(de)查看(kan)(kan)膠皮(pi)外(wai)(wai)，還(huan)要(yao)看(kan)(kan)是(shi)(shi)否有"CCC"認證(zheng)標(biao)識的(de)(de)(de)產(chan)品(pin)(pin)合(he)格(ge)證(zheng)，像商標(biao)、型號規格(ge)、額定電(dian)(dian)(dian)(dian)壓(ya)、長(chang)度(du)、廠(chang)(chang)名、廠(chang)(chang)址等(deng)標(biao)識，這(zhe)些才是(shi)(shi)正規電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜廠(chang)(chang)家(jia)的(de)(de)(de)產(chan)品(pin)(pin)，選購時要(yao)留心(xin)。其(qi)次，要(yao)看(kan)(kan)電(dian)(dian)(dian)(dian)線(xian)的(de)(de)(de)側(ce)面，簡單(dan)來說就是(shi)(shi)能看(kan)(kan)到電(dian)(dian)(dian)(dian)線(xian)里面材質的(de)(de)(de)一(yi)面。主要(yao)查看(kan)(kan)電(dian)(dian)(dian)(dian)線(xian)外(wai)(wai)的(de)(de)(de)一(yi)圈外(wai)(wai)皮(pi)厚度(du)是(shi)(shi)否一(yi)樣（***詞叫：偏心(xin)率）、銅芯是(shi)(shi)否在電(dian)(dian)(dian)(dian)線(xian)的(de)(de)(de)正中間(jian)，如果(guo)有偏離就是(shi)(shi)不合(he)格(ge)的(de)(de)(de)產(chan)品(pin)(pin)。

一(yi)般劣質(zhi)的(de)(de)(de)銅芯(xin)(xin)(xin)尺寸要(yao)比正規(gui)的(de)(de)(de)小，外面(mian)的(de)(de)(de)絕(jue)緣(yuan)(yuan)皮也比較厚，而(er)銅芯(xin)(xin)(xin)本身顏色會偏(pian)黃或偏(pian)白，里面(mian)還(huan)摻有(you)雜(za)質(zhi)，那(nei)么(me)如何判斷銅芯(xin)(xin)(xin)里面(mian)是(shi)(shi)否有(you)雜(za)質(zhi)呢？ RVV電線(xian)(xian)(xian)全稱(cheng)銅芯(xin)(xin)(xin)聚氯(lv)乙烯(xi)絕(jue)緣(yuan)(yuan)聚氯(lv)乙烯(xi)護(hu)(hu)(hu)套(tao)軟(ruan)電線(xian)(xian)(xian)，又稱(cheng)輕型聚氯(lv)乙烯(xi)護(hu)(hu)(hu)套(tao)軟(ruan)線(xian)(xian)(xian),俗稱(cheng)軟(ruan)護(hu)(hu)(hu)套(tao)線(xian)(xian)(xian)，是(shi)(shi)護(hu)(hu)(hu)套(tao)線(xian)(xian)(xian)的(de)(de)(de)一(yi)種。主要(yao)應用于(yu)電器、儀表和電子設備及自動化裝置用電源線(xian)(xian)(xian)、控制線(xian)(xian)(xian)及信號傳輸(shu)線(xian)(xian)(xian)，具體可(ke)用于(yu)防盜報警(jing)系統、樓宇(yu)對講系統等(deng)。方法非常簡單，把銅芯(xin)(xin)(xin)放(fang)在白紙(zhi)(zhi)上(shang)搓一(yi)搓，如果白紙(zhi)(zhi)上(shang)留有(you)黑色的(de)(de)(de)物質(zhi)就是(shi)(shi)雜(za)質(zhi)含量(liang)多。護(hu)(hu)(hu)套(tao)線(xian)(xian)(xian)在構(gou)成上(shang)分為都是(shi)(shi)線(xian)(xian)(xian)芯(xin)(xin)(xin)和兩層絕(jue)緣(yuan)(yuan)外護(hu)(hu)(hu)套(tao)組成的(de)(de)(de)，其中線(xian)(xian)(xian)芯(xin)(xin)(xin)和護(hu)(hu)(hu)套(tao)之間有(you)的(de)(de)(de)還(huan)有(you)一(yi)層聚酯膜做(zuo)的(de)(de)(de)繞包(bao)帶(dai)以增加線(xian)(xian)(xian)芯(xin)(xin)(xin)的(de)(de)(de)緊湊性，同時，有(you)的(de)(de)(de)像(xiang)3芯(xin)(xin)(xin)的(de)(de)(de)等(deng)規(gui)格的(de)(de)(de)軟(ruan)護(hu)(hu)(hu)套(tao)還(huan)會增加一(yi)些(xie)(xie)填充料，使得(de)線(xian)(xian)(xian)體變得(de)圓一(yi)些(xie)(xie)
