具有(you)(you)(you)低煙(yan)無(wu)鹵LSHF（Low Smoke Halogen Free）特(te)性(xing)的(de)(de)(de)電(dian)纜于(yu)20世紀(ji)70年代推出(chu)，***初用于(yu)安裝在小型密閉空間中(zhong)(zhong)，如地鐵、隧道、礦井、船舶和(he)潛(qian)艇(ting)等場(chang)合。隨著(zhu)傳統電(dian)纜在火(huo)(huo)災中(zhong)(zhong)產生煙(yan)霧的(de)(de)(de)毒性(xing)和(he)腐(fu)蝕(shi)(shi)性(xing)的(de)(de)(de)風險越來(lai)越突出(chu)，低煙(yan)無(wu)鹵特(te)性(xing)電(dian)纜的(de)(de)(de)使用范圍擴展到越來(lai)越多的(de)(de)(de)場(chang)所，比如對關鍵設(she)備(bei)和(he)系統連續(xu)運行要求較高(gao)(gao)的(de)(de)(de)數(shu)據中(zhong)(zhong)心、緊(jin)急呼叫中(zhong)(zhong)心和(he)電(dian)信交換(huan)站；以及(ji)學校、醫院和(he)養老(lao)院等無(wu)法有(you)(you)(you)效迅速撤(che)離(li)人員的(de)(de)(de)特(te)殊場(chang)所。雖然(ran)含(han)有(you)(you)(you)鹵化成分的(de)(de)(de)電(dian)纜絕緣和(he)護套具有(you)(you)(you)的(de)(de)(de)阻(zu)燃(ran)性(xing)，但在遇(yu)火(huo)(huo)后會釋(shi)放具有(you)(you)(you)毒性(xing)和(he)腐(fu)蝕(shi)(shi)性(xing)的(de)(de)(de)煙(yan)氣(qi)。遇(yu)火(huo)(huo)后釋(shi)放的(de)(de)(de)鹵素和(he)普(pu)遍存(cun)在的(de)(de)(de)氫氣(qi)反應，形(xing)(xing)成鹵化氫，遇(yu)水后形(xing)(xing)成鹽酸、或。這些(xie)酸可能(neng)會腐(fu)蝕(shi)(shi)重(zhong)要結構、部件和(he)設(she)備(bei)，并增加毒性(xing)。含(han)鹵的(de)(de)(de)電(dian)纜在燃(ran)燒時還會顯著(zhu)提高(gao)(gao)一氧化碳含(han)量，其潛(qian)在危險更(geng)高(gao)(gao)。

實踐證明，在這些商業(ye)和(he)住宅建(jian)(jian)筑(zhu)中(zhong)使(shi)(shi)用低煙(yan)無鹵(lu)(lu)電纜(lan)(lan)有(you)助于減少設備損壞(huai)，降低毒性(xing)煙(yan)氣的(de)釋放，同(tong)時成為(wei)涉及(ji)環境和(he)可持(chi)續因素(su)的(de)綠(lv)色環保新建(jian)(jian)項目的(de)合(he)(he)理選擇。在美國使(shi)(shi)用低煙(yan)無鹵(lu)(lu)電纜(lan)(lan)可能(neng)會滿足(zu)美國綠(lv)色建(jian)(jian)筑(zhu)委員會LEED（Leadership in Energy and Environmental Design）綠(lv)色建(jian)(jian)筑(zhu)倡(chang)議的(de)項目信貸條件。目前電纜(lan)(lan)產品除使(shi)(shi)用金屬(shu)導(dao)體(ti)外，重(zhong)要組成是聚(ju)(ju)合(he)(he)物材(cai)料(liao)。幾十年(nian)來，電纜(lan)(lan)的(de)絕緣和(he)護(hu)套材(cai)料(liao)中(zhong)通常會添(tian)加溴化(hua)(hua)(hua)物等鹵(lu)(lu)化(hua)(hua)(hua)成分來改善阻燃特性(xing)。絕緣和(he)護(hu)套所使(shi)(shi)用的(de)聚(ju)(ju)氯乙(yi)烯(xi)(xi)（PVC），氟化(hua)(hua)(hua)乙(yi)烯(xi)(xi)丙烯(xi)(xi)和(he)氯化(hua)(hua)(hua)聚(ju)(ju)乙(yi)烯(xi)(xi)都含(han)有(you)鹵(lu)(lu)素(su)。其(qi)他用于電纜(lan)(lan)中(zhong)的(de)化(hua)(hua)(hua)合(he)(he)物也有(you)可能(neng)含(han)有(you)其(qi)他鹵(lu)(lu)化(hua)(hua)(hua)成分的(de)樹(shu)脂、添(tian)加劑和(he)色母(mu)。

無鹵電子線由(you)電(dian)子(zi)(zi)(zi)線(xian)(xian)(xian)(xian)延伸而來，符(fu)合歐(ou)盟ROHS標準下的(de)(de)環保(bao)要求，通常用(yong)于弱電(dian)工程，如電(dian)子(zi)(zi)(zi)電(dian)氣(qi)(qi)設(she)備(bei)的(de)(de)內部布線(xian)(xian)(xian)(xian)等(deng)，電(dian)子(zi)(zi)(zi)線(xian)(xian)(xian)(xian)可用(yong)于電(dian)氣(qi)(qi)設(she)備(bei)布線(xian)(xian)(xian)(xian)、發光二極(ji)管模塊線(xian)(xian)(xian)(xian)、家用(yong)電(dian)器(qi)線(xian)(xian)(xian)(xian)、汽車連接(jie)(jie)線(xian)(xian)(xian)(xian)、端子(zi)(zi)(zi)連接(jie)(jie)線(xian)(xian)(xian)(xian)、機(ji)械(xie)內部連接(jie)(jie)線(xian)(xian)(xian)(xian)、照明燈具線(xian)(xian)(xian)(xian)、電(dian)子(zi)(zi)(zi)線(xian)(xian)(xian)(xian)路、變壓器(qi)線(xian)(xian)(xian)(xian)、電(dian)路板連接(jie)(jie)線(xian)(xian)(xian)(xian)、發光二極(ji)管燈條(tiao)線(xian)(xian)(xian)(xian)等(deng)。機(ji)械(xie)損(sun)傷(shang)：無(wu)(wu)鹵(lu)電(dian)子(zi)(zi)(zi)線(xian)(xian)(xian)(xian)被重(zhong)物損(sun)壞，被挖掘機(ji)意外(wai)損(sun)壞，敷設(she)時(shi)(shi)無(wu)(wu)鹵(lu)電(dian)子(zi)(zi)(zi)線(xian)(xian)(xian)(xian)路過(guo)度彎曲，絕(jue)緣(yuan)(yuan)受(shou)損(sun)，運(yun)輸時(shi)(shi)無(wu)(wu)鹵(lu)電(dian)子(zi)(zi)(zi)線(xian)(xian)(xian)(xian)路嚴重(zhong)擠壓，絕(jue)緣(yuan)(yuan)層和保(bao)護層受(shou)損(sun)，底層下沉，直埋(mai)電(dian)纜拉得太大等(deng)，絕(jue)緣(yuan)(yuan)因均而損(sun)壞，甚(shen)至(zhi)無(wu)(wu)鹵(lu)電(dian)子(zi)(zi)(zi)線(xian)(xian)(xian)(xian)路也可能斷裂，為了避(bi)免電(dian)纜的(de)(de)機(ji)械(xie)損(sun)壞，可以使用(yong)架空無(wu)(wu)鹵(lu)電(dian)子(zi)(zi)(zi)線(xian)(xian)(xian)(xian)路，無(wu)(wu)鹵(lu)電(dian)子(zi)(zi)(zi)線(xian)(xian)(xian)(xian)路沿(yan)墻(qiang)敷設(she)時(shi)(shi)，應隱 蔽，地埋(mai)應留有明顯標志，禁止(zhi)在(zai)無(wu)(wu)鹵(lu)電(dian)子(zi)(zi)(zi)線(xian)(xian)(xian)(xian)路周圍取(qu)土。

絕緣受(shou)潮：由于無(wu)鹵(lu)電(dian)(dian)子(zi)(zi)(zi)線(xian)路(lu)(lu)(lu)施工工藝差，濕氣(qi)侵入電(dian)(dian)子(zi)(zi)(zi)線(xian)路(lu)(lu)(lu)內部，或無(wu)鹵(lu)電(dian)(dian)子(zi)(zi)(zi)線(xian)路(lu)(lu)(lu)內保(bao)護(hu)層(ceng)損壞(huai)，濕氣(qi)進(jin)入無(wu)鹵(lu)電(dian)(dian)子(zi)(zi)(zi)線(xian)路(lu)(lu)(lu)；鉛包(bao)電(dian)(dian)纜敷設在(zai)震(zhen)源(yuan)周圍，因長(chang)期振動(dong)而(er)疲勞開裂(lie)，無(wu)鹵(lu)電(dian)(dian)子(zi)(zi)(zi)線(xian)路(lu)(lu)(lu)的(de)外(wai)皮被腐蝕并漂浮，由于制(zhi)造質(zhi)量(liang)不好，鉛包(bao)上有小孔(kong)或裂(lie)紋；鑒于這(zhe)些現(xian)象，應加強無(wu)鹵(lu)電(dian)(dian)子(zi)(zi)(zi)線(xian)路(lu)(lu)(lu)外(wai)層(ceng)的(de)維護(hu)，并按期在(zai)外(wai)保(bao)護(hu)層(ceng)上涂一(yi)層(ceng)瀝青(qing)。過(guo)(guo)電(dian)(dian)壓：無(wu)鹵(lu)電(dian)(dian)子(zi)(zi)(zi)線(xian)路(lu)(lu)(lu)絕緣層(ceng)因大氣(qi)過(guo)(guo)電(dian)(dian)壓或內部過(guo)(guo)電(dian)(dian)壓而(er)擊穿(chuan)，特(te)別是系統內部過(guo)(guo)電(dian)(dian)壓會導致多根電(dian)(dian)纜同時擊穿(chuan)，在(zai)這(zhe)方面，應安(an)裝避雷器。

絕緣(yuan)老化：在無鹵(lu)電(dian)子線路(lu)的長期運(yun)行過(guo)程中，由于散(san)熱不良或(huo)過(guo)載，絕緣(yuan)材料的電(dian)氣和機(ji)械功能變差(cha)，絕緣(yuan)層變脆或(huo)斷裂，如(ru)果是(shi)這種情(qing)況(kuang)，應(ying)定期對無鹵(lu)素(su)電(dian)子線路(lu)進行預防性耐壓測試，在無鹵(lu)電(dian)子線路(lu)絕緣(yuan)降低不符合安全運(yun)行條(tiao)件(jian)，應(ying)更換新(xin)電(dian)纜。
