RVV是(shi)(shi)屬于(yu)電(dian)(dian)(dian)線(xian)(xian)(xian)還是(shi)(shi)電(dian)(dian)(dian)纜(lan)(lan)？它其(qi)(qi)實沒有(you)嚴格意義上的(de)區分，只(zhi)不(bu)(bu)過有(you)人(ren)習慣把規格較(jiao)小的(de)稱(cheng)為(wei)電(dian)(dian)(dian)線(xian)(xian)(xian)，規格大點(dian)的(de)把它叫(jiao)作電(dian)(dian)(dian)纜(lan)(lan)，因(yin)此也被稱(cheng)電(dian)(dian)(dian)纜(lan)(lan)線(xian)(xian)(xian)。RVV是(shi)(shi)電(dian)(dian)(dian)器連接用(yong)的(de)軟電(dian)(dian)(dian)線(xian)(xian)(xian)，常用(yong)于(yu)電(dian)(dian)(dian)壓等級(ji)300/500V及(ji)以(yi)下家用(yong)電(dian)(dian)(dian)器設備用(yong)。RVV電(dian)(dian)(dian)線(xian)(xian)(xian)屬于(yu)3C目(mu)錄(lu)外產品，沒有(you)CCC認證，執(zhi)行標準是(shi)(shi)JB/T8734.2012。RVV電(dian)(dian)(dian)線(xian)(xian)(xian)也稱(cheng)為(wei)護(hu)套線(xian)(xian)(xian)，是(shi)(shi)弱電(dian)(dian)(dian)系統(tong)中較(jiao)常用(yong)的(de)線(xian)(xian)(xian)纜(lan)(lan)，其(qi)(qi)導體芯(xin)數有(you)兩根或以(yi)上，外有(you)PVC護(hu)套層，護(hu)套層的(de)主要作用(yong)是(shi)(shi)保(bao)護(hu)電(dian)(dian)(dian)纜(lan)(lan)內不(bu)(bu)受(shou)機械損傷和化學腐蝕(shi)，可以(yi)增強電(dian)(dian)(dian)線(xian)(xian)(xian)的(de)機械強度，這也是(shi)(shi)其(qi)(qi)名(ming)稱(cheng)的(de)由來。

在日常生(sheng)活(huo)中，不(bu)(bu)管(guan)是(shi)辦(ban)公用(yong)電(dian)(dian)(dian)(dian)，還是(shi)家庭用(yong)電(dian)(dian)(dian)(dian)，有兩大問(wen)題是(shi)不(bu)(bu)容忽視的，那就是(shi)安全(quan)、環(huan)保問(wen)題。用(yong)電(dian)(dian)(dian)(dian)安全(quan)一旦出現紕漏，情況輕的話(hua)會損(sun)壞電(dian)(dian)(dian)(dian)器(qi)，增加維修成(cheng)本；嚴(yan)重(zhong)的話(hua)就會引(yin)發火災，給(gei)人(ren)(ren)們帶(dai)來不(bu)(bu)可估量的損(sun)失(shi)。同時(shi)，若所(suo)用(yong)的電(dian)(dian)(dian)(dian)線(xian)是(shi)不(bu)(bu)達標(biao)、不(bu)(bu)環(huan)保的，不(bu)(bu)僅會對環(huan)境造(zao)(zao)成(cheng)污(wu)染，還會對人(ren)(ren)體健康造(zao)(zao)成(cheng)傷害(hai)，因此，很(hen)多人(ren)(ren)在選擇(ze)電(dian)(dian)(dian)(dian)線(xian)時(shi)，更傾向于選擇(ze)防火電(dian)(dian)(dian)(dian)線(xian)，

防(fang)火(huo)(huo)電線(xian)(xian)具有高(gao)阻燃性，符合綠色***建筑要求，這樣(yang)的電線(xian)(xian)不易燃燒(shao)起火(huo)(huo)，即使(shi)(shi)燃燒(shao)也能阻止(zhi)火(huo)(huo)焰的蔓延，降低火(huo)(huo)災危害。防(fang)火(huo)(huo)電線(xian)(xian)使(shi)(shi)用綠色絕緣護套(tao)和特(te)殊(shu)的氧(yang)氣阻隔(ge)性材料，不含(han)鉛，鎘等有害重(zhong)金(jin)屬(shu)，不僅具有良(liang)好的電氣性能，機械性能，也避免了傳統(tong)的PVC電線(xian)(xian)在燃燒(shao)時產生(sheng)致癌(ai)類(lei)的物質，有害人體健(jian)康。

在大電(dian)流發(fa)生(sheng)器(qi)的(de)(de)作用下(xia)，防火(huo)(huo)(huo)電(dian)線(xian)(xian)(xian)并不(bu)像普通(tong)PVC電(dian)線(xian)(xian)(xian)那(nei)般容易起火(huo)(huo)(huo)燃(ran)燒，相反它(ta)優(you)異(yi)的(de)(de)防過(guo)載，使(shi)它(ta)依然完好(hao)無損(sun)。防火(huo)(huo)(huo)電(dian)線(xian)(xian)(xian)外表包裹的(de)(de)電(dian)線(xian)(xian)(xian)絕(jue)緣(yuan)皮(pi)，質量要優(you)于普通(tong)電(dian)線(xian)(xian)(xian)。就好(hao)比創遠防火(huo)(huo)(huo)電(dian)線(xian)(xian)(xian)，它(ta)是由阻燃(ran)交聯聚烯烴材料、防火(huo)(huo)(huo)墻(qiang)和(he)導體三部分組(zu)成的(de)(de)，耐腐蝕(shi)、抗老(lao)化(hua)、使(shi)用壽命長(chang)。

超負荷運行，ul電子線由(you)于電(dian)(dian)流(liu)(liu)的熱(re)(re)效應，負載電(dian)(dian)流(liu)(liu)通過電(dian)(dian)纜(lan)(lan)(lan)時致使(shi)(shi)導體發熱(re)(re)，同時電(dian)(dian)荷的集膚效應以(yi)及鋼鎧的渦流(liu)(liu)損(sun)耗、絕(jue)(jue)(jue)緣介(jie)質(zhi)損(sun)耗也會產(chan)乍附加熱(re)(re)量，從而使(shi)(shi)電(dian)(dian)纜(lan)(lan)(lan)溫度升高。長期(qi)超負荷運行時，過高的溫度會加速(su)絕(jue)(jue)(jue)緣的老化(hua)，以(yi)至絕(jue)(jue)(jue)緣被擊(ji)(ji)穿(chuan)。尤其在炎熱(re)(re)的夏(xia)季，電(dian)(dian)纜(lan)(lan)(lan)的溫升常常致使(shi)(shi)電(dian)(dian)纜(lan)(lan)(lan)絕(jue)(jue)(jue)緣薄(bo)弱處(chu)首先被擊(ji)(ji)穿(chuan)，因(yin)此在夏(xia)季，ul電(dian)(dian)子線電(dian)(dian)纜(lan)(lan)(lan)的故障(zhang)也就特別多。

ul電子線電纜的制造與大多數機電產品的生產方式是完全不同的。機電產品通常采用將另件裝配成部件、多個部件再裝配成單臺產品，產品以臺數或件數計量。電線電纜是以長度為基本計量單位。所有電線電纜都是從導體加工開始，在導體的外圍一層一層地加上絕緣、屏蔽、、成纜、護層等而制成電線電纜產品。產品結構越復雜，疊加的層次就越多。

ul電(dian)(dian)(dian)(dian)子線長(chang)期過(guo)負(fu)荷運行超負(fu)荷運行，由于電(dian)(dian)(dian)(dian)流的熱效應，負(fu)載電(dian)(dian)(dian)(dian)流通過(guo)電(dian)(dian)(dian)(dian)纜(lan)時(shi)致使導(dao)體發熱，同時(shi)電(dian)(dian)(dian)(dian)荷的集膚效應以及(ji)鋼(gang)鎧的渦流損耗、絕緣介質損耗也會(hui)產乍(zha)附加熱量，從而(er)使電(dian)(dian)(dian)(dian)纜(lan)溫(wen)度(du)升高。長(chang)期超負(fu)荷運行時(shi)，過(guo)高的溫(wen)度(du)會(hui)加速絕緣的老(lao)化(hua)，以至絕緣被擊(ji)穿。尤其在炎熱的夏季(ji)，電(dian)(dian)(dian)(dian)纜(lan)的溫(wen)升常(chang)常(chang)致使電(dian)(dian)(dian)(dian)纜(lan)絕緣薄弱處首先被擊(ji)穿，因此在夏季(ji)，電(dian)(dian)(dian)(dian)纜(lan)的故障也就(jiu)特(te)別(bie)多(duo)。

ul電子線電纜屬于電氣裝備電纜居多，也較為常見，電氣裝備電纜分為：布電線、電氣安裝用電纜、計算機控制電纜、控制電纜、交通運輸裝備電纜、航空航天器材使用電纜、礦用電纜、信號電纜。因其特殊的使用環境及苛刻的要求使得定制電纜的發展也逐年加快，要求更高，壽命強，功能更強。
