具有低(di)煙無鹵(lu)(lu)(lu)(lu)(lu)LSHF（Low Smoke Halogen Free）特性(xing)的(de)(de)(de)電(dian)(dian)纜于(yu)20世紀70年(nian)代推(tui)出(chu)，初用于(yu)安(an)裝在(zai)小型密閉空間(jian)中，如地鐵、隧(sui)道、礦井(jing)、船舶和潛艇等場合。隨著傳統(tong)電(dian)(dian)纜在(zai)火(huo)災中產生煙霧的(de)(de)(de)毒性(xing)和腐(fu)蝕性(xing)的(de)(de)(de)風險越來越突出(chu)，低(di)煙無鹵(lu)(lu)(lu)(lu)(lu)特性(xing)電(dian)(dian)纜的(de)(de)(de)使用范圍擴展到越來越多的(de)(de)(de)場所(suo)，比如對關(guan)鍵(jian)設備和系統(tong)連續運(yun)行要(yao)求較高(gao)的(de)(de)(de)數據(ju)中心、緊急呼(hu)叫中心和電(dian)(dian)信交換站；以及學校、醫院和養老(lao)院等無法有效迅速撤離人員的(de)(de)(de)特殊場所(suo)。雖然(ran)含有鹵(lu)(lu)(lu)(lu)(lu)化(hua)成分(fen)的(de)(de)(de)電(dian)(dian)纜絕緣和護套具有的(de)(de)(de)阻燃性(xing)，但在(zai)遇(yu)火(huo)后(hou)會釋(shi)放(fang)具有毒性(xing)和腐(fu)蝕性(xing)的(de)(de)(de)煙氣。遇(yu)火(huo)后(hou)釋(shi)放(fang)的(de)(de)(de)鹵(lu)(lu)(lu)(lu)(lu)素(su)和普(pu)遍存(cun)在(zai)的(de)(de)(de)氫氣反應，形(xing)成鹵(lu)(lu)(lu)(lu)(lu)化(hua)氫，遇(yu)水后(hou)形(xing)成鹽(yan)酸、或。這些酸可能會腐(fu)蝕重要(yao)結構、部(bu)件和設備，并增加毒性(xing)。含鹵(lu)(lu)(lu)(lu)(lu)的(de)(de)(de)電(dian)(dian)纜在(zai)燃燒時還(huan)會顯著提高(gao)一氧(yang)化(hua)碳含量，其(qi)潛在(zai)危險更高(gao)。

實踐證明，在(zai)這些商業和(he)住宅建筑中使(shi)用(yong)低煙無鹵(lu)電纜(lan)有(you)助(zhu)于減少設備損壞，降低毒性(xing)(xing)煙氣(qi)的(de)(de)(de)釋放，同時成(cheng)為涉(she)及環境(jing)和(he)可持續因素(su)的(de)(de)(de)綠色(se)環保新建項目(mu)(mu)的(de)(de)(de)合理(li)選(xuan)擇(ze)。在(zai)美國使(shi)用(yong)低煙無鹵(lu)電纜(lan)可能(neng)會(hui)(hui)滿(man)足(zu)美國綠色(se)建筑委員會(hui)(hui)LEED（Leadership in Energy and Environmental Design）綠色(se)建筑倡(chang)議的(de)(de)(de)項目(mu)(mu)信貸條(tiao)件。目(mu)(mu)前電纜(lan)產品除使(shi)用(yong)金屬導體外，重要組成(cheng)是聚合物材料。幾十(shi)年來，電纜(lan)的(de)(de)(de)絕緣和(he)護套材料中通常會(hui)(hui)添加溴化(hua)(hua)物等(deng)鹵(lu)化(hua)(hua)成(cheng)分(fen)來改善阻燃特性(xing)(xing)。絕緣和(he)護套所使(shi)用(yong)的(de)(de)(de)聚氯(lv)乙烯(xi)（PVC），氟(fu)化(hua)(hua)乙烯(xi)丙烯(xi)和(he)氯(lv)化(hua)(hua)聚乙烯(xi)都含有(you)鹵(lu)素(su)。其(qi)他(ta)用(yong)于電纜(lan)中的(de)(de)(de)化(hua)(hua)合物也有(you)可能(neng)含有(you)其(qi)他(ta)鹵(lu)化(hua)(hua)成(cheng)分(fen)的(de)(de)(de)樹脂、添加劑和(he)色(se)母。

家居級-CMX級（垂(chui)直(zhi)燃(ran)燒(shao)(shao)(shao)測試Vertial Wire Flame Test）這是(shi)UL標準(zhun)中家居級電纜(lan)（RestrictedCable），適用(yong)安全標準(zhun)為(wei)UL1581，VW-1。實驗(yan)規定試樣保持垂(chui)直(zhi)，用(yong)試驗(yan)用(yong)的噴燈燃(ran)燒(shao)(shao)(shao)（30，000 TU/Hr）15秒鐘(zhong)，然后停止15秒鐘(zhong)，反復(fu)5次。合格標準(zhun)為(wei)余火焰不可超過60秒鐘(zhong)，試樣不可燒(shao)(shao)(shao)損25%以(yi)上，墊在(zai)底(di)部(bu)的外科用(yong)棉不可被落(luo)下物引燃(ran)。UL1581-VW-1和(he)IEC60332-1類(lei)似，只是(shi)燃(ran)燒(shao)(shao)(shao)的時間不同。這種等級也沒有煙(yan)霧(wu)或毒性(xing)規范，僅用(yong)于敷(fu)設(she)單條電纜(lan)的家庭或小型(xing)辦(ban)公室系統中,這類(lei)電纜(lan)不應成(cheng)捆敷(fu)設(she)使(shi)用(yong)，***套管(guan).
