UL1430-日照UL無鹵電線-泰安UL無鹵電線。

具有(you)低煙無鹵(lu)(lu)LSHF（Low Smoke Halogen Free）特性(xing)(xing)的(de)(de)(de)電(dian)(dian)(dian)纜于20世紀70年代推出，***初用于安裝在(zai)小型密閉(bi)空間中，如(ru)(ru)地鐵(tie)、隧道(dao)、礦井、船舶和(he)(he)潛艇等場(chang)合。隨著傳統(tong)電(dian)(dian)(dian)纜在(zai)火災中產生煙霧的(de)(de)(de)毒(du)(du)性(xing)(xing)和(he)(he)腐蝕性(xing)(xing)的(de)(de)(de)風險(xian)越(yue)(yue)來越(yue)(yue)突出，低煙無鹵(lu)(lu)特性(xing)(xing)電(dian)(dian)(dian)纜的(de)(de)(de)使用范圍(wei)擴展到越(yue)(yue)來越(yue)(yue)多的(de)(de)(de)場(chang)所，比(bi)如(ru)(ru)對關(guan)鍵設備和(he)(he)系統(tong)連續運行(xing)要(yao)(yao)求(qiu)較高(gao)(gao)的(de)(de)(de)數據中心、緊(jin)急呼叫(jiao)中心和(he)(he)電(dian)(dian)(dian)信交換(huan)站(zhan)；以及學校(xiao)、醫院(yuan)和(he)(he)養老(lao)院(yuan)等無法(fa)有(you)效迅速撤(che)離人員的(de)(de)(de)特殊(shu)場(chang)所。雖然含(han)有(you)鹵(lu)(lu)化(hua)成分的(de)(de)(de)電(dian)(dian)(dian)纜絕緣和(he)(he)護套具有(you)的(de)(de)(de)阻燃性(xing)(xing)，但在(zai)遇火后會(hui)釋放(fang)具有(you)毒(du)(du)性(xing)(xing)和(he)(he)腐蝕性(xing)(xing)的(de)(de)(de)煙氣。遇火后釋放(fang)的(de)(de)(de)鹵(lu)(lu)素和(he)(he)普遍存在(zai)的(de)(de)(de)氫(qing)氣反應，形(xing)成鹵(lu)(lu)化(hua)氫(qing)，遇水后形(xing)成鹽酸、或。這些酸可能會(hui)腐蝕重要(yao)(yao)結構(gou)、部件和(he)(he)設備，并增加毒(du)(du)性(xing)(xing)。含(han)鹵(lu)(lu)的(de)(de)(de)電(dian)(dian)(dian)纜在(zai)燃燒(shao)時(shi)還會(hui)顯著提高(gao)(gao)一氧化(hua)碳含(han)量，其潛在(zai)危險(xian)更高(gao)(gao)。

實踐(jian)證明，在這些(xie)商業(ye)和(he)(he)住宅建(jian)筑(zhu)中使(shi)用(yong)(yong)低(di)煙無(wu)鹵電(dian)(dian)(dian)纜(lan)(lan)(lan)有(you)助于減(jian)少設備損壞(huai)，降低(di)毒性(xing)(xing)煙氣的(de)(de)(de)釋放，同(tong)時成(cheng)為(wei)涉(she)及環(huan)境和(he)(he)可持續因素的(de)(de)(de)綠色(se)環(huan)保新建(jian)項目的(de)(de)(de)合(he)(he)理選擇。在美(mei)國使(shi)用(yong)(yong)低(di)煙無(wu)鹵電(dian)(dian)(dian)纜(lan)(lan)(lan)可能(neng)會滿足(zu)美(mei)國綠色(se)建(jian)筑(zhu)委員會LEED（Leadership in Energy and Environmental Design）綠色(se)建(jian)筑(zhu)倡(chang)議的(de)(de)(de)項目信貸條件(jian)。目前電(dian)(dian)(dian)纜(lan)(lan)(lan)產品除使(shi)用(yong)(yong)金屬導體外，重要組成(cheng)是(shi)聚(ju)合(he)(he)物材料。幾十(shi)年(nian)來(lai)，電(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)(de)(de)絕緣和(he)(he)護套材料中通常會添加溴化(hua)(hua)物等鹵化(hua)(hua)成(cheng)分來(lai)改善(shan)阻燃(ran)特性(xing)(xing)。絕緣和(he)(he)護套所使(shi)用(yong)(yong)的(de)(de)(de)聚(ju)氯(lv)乙烯(xi)（PVC），氟(fu)化(hua)(hua)乙烯(xi)丙(bing)烯(xi)和(he)(he)氯(lv)化(hua)(hua)聚(ju)乙烯(xi)都含有(you)鹵素。其他用(yong)(yong)于電(dian)(dian)(dian)纜(lan)(lan)(lan)中的(de)(de)(de)化(hua)(hua)合(he)(he)物也有(you)可能(neng)含有(you)其他鹵化(hua)(hua)成(cheng)分的(de)(de)(de)樹脂、添加劑和(he)(he)色(se)母。

在商業和(he)住(zhu)宅建筑項目中(zhong)使(shi)用(yong)低(di)煙無鹵（下文簡(jian)稱LSHF）電(dian)纜(lan)有(you)助于減(jian)少設備損壞和(he)降(jiang)低(di)煙氣毒性。然而，目前生產(chan)商、產(chan)品專家和(he)承包商對(dui)LSHF標(biao)(biao)(biao)識的確切(qie)含義，以及(ji)對(dui)電(dian)纜(lan)能(neng)完全符合(he)LSHF要求(qiu)而按照標(biao)(biao)(biao)準要求(qiu)所進行(xing)的廣泛測試(shi)仍然存在很多困(kun)惑。為此UL制(zhi)訂了UL 2885（IEC 62821-1和(he)-2）標(biao)(biao)(biao)準，該標(biao)(biao)(biao)準規定了帶(dai)有(you)HF和(he)LSHF標(biao)(biao)(biao)記的電(dian)纜(lan)中(zhong)使(shi)用(yong)的化合(he)物、組分(fen)或(huo)材料(liao)要求(qiu)。由此生產(chan)出來的電(dian)纜(lan)產(chan)品能(neng)符合(he)LSHF規范。

制造商在其終端產品成功通過UL認證檢測后，可獲得授權，產品投產時能夠在產品上貼附UL標志。制造商屆時會從UL收到《跟蹤檢驗服務程序書》，其中提供了對***初提交至UL的整體產品及其各個零部件的描述。該程序書還定義了在產品上使用UL標志的適用條款和條件。UL 提供認證后的“標志完整性程序”，驗證產品對UL規定的持續符合性，主要包含以下幾個要素：

在工廠檢查(cha)期間，要驗證(zheng)終端產品中使用的(de)(de)(de)零部(bu)(bu)(bu)件(jian)(jian)，是否符(fu)合UL 要求(qiu)，其中關(guan)鍵(jian)在于確認(ren)這些零部(bu)(bu)(bu)件(jian)(jian)是否與其在程序書中的(de)(de)(de)描述(shu)一致。確認(ren)UL認(ren)證(zheng)的(de)(de)(de)終端產品中使用的(de)(de)(de)零部(bu)(bu)(bu)件(jian)(jian)的(de)(de)(de)合規性(xing)(xing)，也是向市場推(tui)廣更安全產品的(de)(de)(de)重要一步。此外，維持(chi)這些零部(bu)(bu)(bu)件(jian)(jian)的(de)(de)(de)可追溯(su)性(xing)(xing)有助于為供(gong)應鏈的(de)(de)(de)持(chi)續完整性(xing)(xing)提供(gong)支持(chi)，從而(er)為所收到零部(bu)(bu)(bu)件(jian)(jian)對(dui)采(cai)購要求(qiu)的(de)(de)(de)符(fu)合性(xing)(xing)實現更高的(de)(de)(de)置信度。

UL1430-日照UL無鹵電線-泰安UL無鹵電線。

無鹵電子線由電(dian)(dian)子(zi)(zi)(zi)線(xian)(xian)(xian)(xian)(xian)延伸而來(lai)，符合歐(ou)盟ROHS標準下的(de)環保(bao)要求，通常用(yong)(yong)于弱(ruo)電(dian)(dian)工程，如電(dian)(dian)子(zi)(zi)(zi)電(dian)(dian)氣設備(bei)的(de)內部布線(xian)(xian)(xian)(xian)(xian)等，電(dian)(dian)子(zi)(zi)(zi)線(xian)(xian)(xian)(xian)(xian)可用(yong)(yong)于電(dian)(dian)氣設備(bei)布線(xian)(xian)(xian)(xian)(xian)、發(fa)光二極管模(mo)塊(kuai)線(xian)(xian)(xian)(xian)(xian)、家用(yong)(yong)電(dian)(dian)器線(xian)(xian)(xian)(xian)(xian)、汽(qi)車連(lian)接(jie)線(xian)(xian)(xian)(xian)(xian)、端子(zi)(zi)(zi)連(lian)接(jie)線(xian)(xian)(xian)(xian)(xian)、機(ji)械(xie)內部連(lian)接(jie)線(xian)(xian)(xian)(xian)(xian)、照明燈(deng)(deng)具(ju)線(xian)(xian)(xian)(xian)(xian)、電(dian)(dian)子(zi)(zi)(zi)線(xian)(xian)(xian)(xian)(xian)路(lu)、變壓器線(xian)(xian)(xian)(xian)(xian)、電(dian)(dian)路(lu)板連(lian)接(jie)線(xian)(xian)(xian)(xian)(xian)、發(fa)光二極管燈(deng)(deng)條線(xian)(xian)(xian)(xian)(xian)等。機(ji)械(xie)損(sun)(sun)傷：無(wu)(wu)鹵(lu)(lu)電(dian)(dian)子(zi)(zi)(zi)線(xian)(xian)(xian)(xian)(xian)被重物損(sun)(sun)壞，被挖(wa)掘機(ji)意外損(sun)(sun)壞，敷(fu)設時無(wu)(wu)鹵(lu)(lu)電(dian)(dian)子(zi)(zi)(zi)線(xian)(xian)(xian)(xian)(xian)路(lu)過(guo)度(du)彎曲，絕緣(yuan)受(shou)損(sun)(sun)，運輸(shu)時無(wu)(wu)鹵(lu)(lu)電(dian)(dian)子(zi)(zi)(zi)線(xian)(xian)(xian)(xian)(xian)路(lu)嚴(yan)重擠壓，絕緣(yuan)層(ceng)和保(bao)護層(ceng)受(shou)損(sun)(sun)，底層(ceng)下沉，直埋(mai)電(dian)(dian)纜拉得太大等，絕緣(yuan)因均而損(sun)(sun)壞，甚至無(wu)(wu)鹵(lu)(lu)電(dian)(dian)子(zi)(zi)(zi)線(xian)(xian)(xian)(xian)(xian)路(lu)也可能斷裂，為了避免電(dian)(dian)纜的(de)機(ji)械(xie)損(sun)(sun)壞，可以使用(yong)(yong)架空無(wu)(wu)鹵(lu)(lu)電(dian)(dian)子(zi)(zi)(zi)線(xian)(xian)(xian)(xian)(xian)路(lu)，無(wu)(wu)鹵(lu)(lu)電(dian)(dian)子(zi)(zi)(zi)線(xian)(xian)(xian)(xian)(xian)路(lu)沿墻敷(fu)設時，應隱 蔽，地埋(mai)應留有明顯標志(zhi)，禁止在無(wu)(wu)鹵(lu)(lu)電(dian)(dian)子(zi)(zi)(zi)線(xian)(xian)(xian)(xian)(xian)路(lu)周圍取土。

絕緣(yuan)受潮：由于無(wu)鹵(lu)(lu)電(dian)子線(xian)路(lu)(lu)(lu)施工工藝(yi)差，濕氣侵(qin)入電(dian)子線(xian)路(lu)(lu)(lu)內(nei)(nei)部(bu)，或無(wu)鹵(lu)(lu)電(dian)子線(xian)路(lu)(lu)(lu)內(nei)(nei)保(bao)護(hu)層(ceng)(ceng)損壞，濕氣進入無(wu)鹵(lu)(lu)電(dian)子線(xian)路(lu)(lu)(lu)；鉛(qian)包電(dian)纜敷設在(zai)(zai)震源周(zhou)圍，因長期振動而(er)(er)疲勞開裂，無(wu)鹵(lu)(lu)電(dian)子線(xian)路(lu)(lu)(lu)的(de)外(wai)(wai)皮被腐蝕并(bing)漂浮，由于制造質(zhi)量(liang)不(bu)好，鉛(qian)包上有小孔或裂紋；鑒于這些現象，應加(jia)強無(wu)鹵(lu)(lu)電(dian)子線(xian)路(lu)(lu)(lu)外(wai)(wai)層(ceng)(ceng)的(de)維護(hu)，并(bing)按期在(zai)(zai)外(wai)(wai)保(bao)護(hu)層(ceng)(ceng)上涂一層(ceng)(ceng)瀝青。過(guo)(guo)電(dian)壓(ya)：無(wu)鹵(lu)(lu)電(dian)子線(xian)路(lu)(lu)(lu)絕緣(yuan)層(ceng)(ceng)因大氣過(guo)(guo)電(dian)壓(ya)或內(nei)(nei)部(bu)過(guo)(guo)電(dian)壓(ya)而(er)(er)擊穿，特別是系(xi)統內(nei)(nei)部(bu)過(guo)(guo)電(dian)壓(ya)會導(dao)致多根電(dian)纜同(tong)時(shi)擊穿，在(zai)(zai)這方面，應安裝避雷器(qi)。

絕(jue)(jue)緣老化：在無(wu)鹵電(dian)子(zi)線(xian)路(lu)(lu)的(de)長期運行過程中，由于散熱(re)不良或過載，絕(jue)(jue)緣材料的(de)電(dian)氣(qi)和機(ji)械功(gong)能變(bian)差，絕(jue)(jue)緣層變(bian)脆(cui)或斷裂(lie)，如(ru)果是這種情況，應定期對(dui)無(wu)鹵素(su)電(dian)子(zi)線(xian)路(lu)(lu)進(jin)行預防性耐壓測(ce)試，在無(wu)鹵電(dian)子(zi)線(xian)路(lu)(lu)絕(jue)(jue)緣降低不符合安全運行條件，應更換(huan)新電(dian)纜。
