許多上(shang)市阻(zu)燃電(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)電(dian)(dian)(dian)氣和(he)電(dian)(dian)(dian)子布(bu)線(xian)系統(tong)電(dian)(dian)(dian)纜(lan)(lan)連接到一(yi)個(ge)經認(ren)可的(de)(de)(de)機構如(ru)UL（美國保險商實驗(yan)室(shi)）與(yu)“上(shang)市”。，如(ru)在(zai)特定(ding)(ding)的(de)(de)(de)環(huan)境中使(shi)用(yong)(yong)的(de)(de)(de)電(dian)(dian)(dian)纜(lan)(lan)也(ye)***是“分類”的(de)(de)(de)應(ying)用(yong)(yong)程序。要獲(huo)得一(yi)個(ge)分類，設備或(huo)電(dian)(dian)(dian)纜(lan)(lan)***通(tong)(tong)過測試(shi)的(de)(de)(de)應(ying)用(yong)(yong)或(huo)安(an)裝型。所有電(dian)(dian)(dian)纜(lan)(lan)在(zai)全(quan)(quan)會(hui)的(de)(de)(de)應(ying)用(yong)(yong)程序的(de)(de)(de)情況下(xia)，***通(tong)(tong)過UL 910施泰(tai)納風洞試(shi)驗(yan)。CCI阻(zu)燃電(dian)(dian)(dian)纜(lan)(lan)都列出了UL和(he)NEC的(de)(de)(de)在(zai)全(quan)(quan)會(hui)安(an)裝使(shi)用(yong)(yong)。謹(jin)防假(jia)冒“阻(zu)燃上(shang)市”或(huo)“全(quan)(quan)會(hui)批準”。這些電(dian)(dian)(dian)纜(lan)(lan)可能(neng)不(bu)符合UL及(ji)NEC的(de)(de)(de)要求。所有列出的(de)(de)(de)分類電(dian)(dian)(dian)纜(lan)(lan)***確定(ding)(ding)每一(yi)個(ge)24英(ying)寸的(de)(de)(de)外套或(huo)內部標記磁帶上(shang)打印。

RVV是(shi)(shi)屬于電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)還是(shi)(shi)電(dian)(dian)(dian)(dian)纜(lan)(lan)？它(ta)其(qi)實沒(mei)有嚴(yan)格意義上(shang)的(de)區(qu)分(fen)，只不過有人習(xi)慣把規格較小(xiao)的(de)稱(cheng)(cheng)為電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)，規格大點的(de)把它(ta)叫(jiao)作電(dian)(dian)(dian)(dian)纜(lan)(lan)，因此也(ye)(ye)被稱(cheng)(cheng)電(dian)(dian)(dian)(dian)纜(lan)(lan)線(xian)(xian)(xian)(xian)。RVV是(shi)(shi)電(dian)(dian)(dian)(dian)器(qi)連接用的(de)軟電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)，常(chang)(chang)用于電(dian)(dian)(dian)(dian)壓(ya)等級300/500V及以(yi)下家用電(dian)(dian)(dian)(dian)器(qi)設備用。RVV電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)屬于3C目(mu)錄(lu)外產品，沒(mei)有CCC認(ren)證，執行標準(zhun)是(shi)(shi)JB/T8734.2012。RVV電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)也(ye)(ye)稱(cheng)(cheng)為護(hu)套線(xian)(xian)(xian)(xian)，是(shi)(shi)弱電(dian)(dian)(dian)(dian)系統(tong)中較常(chang)(chang)用的(de)線(xian)(xian)(xian)(xian)纜(lan)(lan)，其(qi)導體芯(xin)數(shu)有兩根或(huo)以(yi)上(shang)，外有PVC護(hu)套層，護(hu)套層的(de)主要作用是(shi)(shi)保護(hu)電(dian)(dian)(dian)(dian)纜(lan)(lan)內不受機(ji)械損傷和化學腐(fu)蝕，可以(yi)增強電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)的(de)機(ji)械強度，這也(ye)(ye)是(shi)(shi)其(qi)名稱(cheng)(cheng)的(de)由來。

UL電子線的(de)塑(su)(su)(su)料(liao)具有(you)(you)(you)彈(dan)(dan)性(xing)，有(you)(you)(you)些塑(su)(su)(su)料(liao)也像組成(cheng)(cheng)纖維一樣，具有(you)(you)(you)必然的(de)彈(dan)(dan)性(xing)。當它遭到外力拉(la)(la)伸時，卷曲的(de)分子就由柔韌(ren)性(xing)而被拉(la)(la)直，但一旦拉(la)(la)力作廢(fei)后，它又會恢恢復來的(de)卷曲形態(tai)，如許就使得(de)塑(su)(su)(su)料(liao)具有(you)(you)(you)彈(dan)(dan)性(xing)，例如聚乙烯(xi)和聚氯乙烯(xi)的(de)薄膜成(cheng)(cheng)品。然而有(you)(you)(you)些塑(su)(su)(su)料(liao)是(shi)沒(mei)有(you)(you)(you)彈(dan)(dan)性(xing)的(de)，塑(su)(su)(su)料(liao)具有(you)(you)(you)較(jiao)(jiao)高的(de)強度：塑(su)(su)(su)料(liao)雖(sui)然沒(mei)有(you)(you)(you)金屬那樣堅固，但與陶(tao)瓷、玻(bo)璃、木材(cai)等比擬，照樣具有(you)(you)(you)比較(jiao)(jiao)高的(de)強度及耐磨性(xing)。塑(su)(su)(su)料(liao)可以制成(cheng)(cheng)機械上穩(wen)固的(de)齒輪和軸(zhou)承(cheng)。

ul電子線束的保護層與結構，電子線束的保護層在電線中能起到改良電場結構的，防止因導體外觀崛起激發放電，電子線削減部分放電量，保障電線的獨霸壽命和靠得住性。比來，在標準中都有電壓等第5kv的礦用橡套電纜，而且都對該電壓等第的橡套電纜提出了導體保護的條件，該保護層***采用圍繞編制從事。憑證這一條件，礦用橡套電纜也須有導體包庇層就可以夠保障電纜的安然運行。

ul電(dian)子線(xian)以(yi)及(ji)各種電(dian)子專用(yong)的(de)特殊連接線(xian)。產(chan)品廣泛用(yong)于手(shou)機(ji)、數碼相機(ji)、機(ji)頂盒(he)、復印機(ji)、傳真機(ji)、儀器(qi)儀表、電(dian)源(yuan)、充電(dian)器(qi)、馬(ma)達、音(yin)響、顯示(shi)器(qi)、空調、冰箱(xiang)、醫療設備、教學設備、玩(wan)具(ju)、汽車、家(jia)用(yong)電(dian)器(qi)以(yi)及(ji)電(dian)路板(ban)等產(chan)品的(de)連接領域。

環保ul電子線的生產設備是電子輻照加速器，主要組成部分：高壓發生器、電子槍和加速管、速流引出系統、收放線裝置、計算機控制系統和必要的檢測設備。生產原理是利用電子輻照加速器的高能電子速流對電線電纜絕緣層及保護層進行輻照，塑性體原相對獨立的鏈狀結構變成同層相連、層層相連的三維網狀結構，從而地提高了電線電纜產品的機械物理性能，耐熱性和使用壽命等等。
