具(ju)有低煙(yan)無鹵(lu)(lu)LSHF(Low Smoke Halogen Free)特(te)性(xing)(xing)的(de)電(dian)(dian)纜(lan)(lan)于(yu)20世紀70年代推出,***初用于(yu)安裝在(zai)(zai)(zai)小型密閉空間中(zhong)(zhong),如(ru)地鐵、隧道、礦井、船舶(bo)和(he)(he)(he)潛(qian)艇等(deng)場合(he)。隨著傳(chuan)統(tong)(tong)電(dian)(dian)纜(lan)(lan)在(zai)(zai)(zai)火災中(zhong)(zhong)產生(sheng)煙(yan)霧的(de)毒性(xing)(xing)和(he)(he)(he)腐(fu)蝕(shi)性(xing)(xing)的(de)風險越來越突出,低煙(yan)無鹵(lu)(lu)特(te)性(xing)(xing)電(dian)(dian)纜(lan)(lan)的(de)使用范圍(wei)擴展到越來越多(duo)的(de)場所,比如(ru)對關鍵(jian)設備和(he)(he)(he)系統(tong)(tong)連續運行(xing)要(yao)求較(jiao)高的(de)數據中(zhong)(zhong)心(xin)(xin)、緊急呼叫中(zhong)(zhong)心(xin)(xin)和(he)(he)(he)電(dian)(dian)信交換站;以及學(xue)校、醫(yi)院(yuan)和(he)(he)(he)養(yang)老院(yuan)等(deng)無法有效迅速(su)撤離人員的(de)特(te)殊場所。雖然含有鹵(lu)(lu)化(hua)成分的(de)電(dian)(dian)纜(lan)(lan)絕緣和(he)(he)(he)護套具(ju)有的(de)阻(zu)燃(ran)性(xing)(xing),但在(zai)(zai)(zai)遇火后會釋放具(ju)有毒性(xing)(xing)和(he)(he)(he)腐(fu)蝕(shi)性(xing)(xing)的(de)煙(yan)氣。遇火后釋放的(de)鹵(lu)(lu)素和(he)(he)(he)普遍存在(zai)(zai)(zai)的(de)氫氣反應,形成鹵(lu)(lu)化(hua)氫,遇水后形成鹽(yan)酸、或。這(zhe)些酸可能會腐(fu)蝕(shi)重要(yao)結(jie)構、部件和(he)(he)(he)設備,并增加(jia)毒性(xing)(xing)。含鹵(lu)(lu)的(de)電(dian)(dian)纜(lan)(lan)在(zai)(zai)(zai)燃(ran)燒時還會顯著提高一氧化(hua)碳含量(liang),其潛(qian)在(zai)(zai)(zai)危險更(geng)高。
實踐(jian)證明(ming),在(zai)這些商業(ye)和(he)(he)住宅建(jian)筑中(zhong)使用低(di)煙(yan)無鹵(lu)電(dian)(dian)纜(lan)(lan)(lan)有(you)(you)助于減(jian)少設(she)備損壞,降低(di)毒性(xing)煙(yan)氣的(de)(de)(de)釋放(fang),同(tong)時成(cheng)(cheng)為涉及環(huan)境和(he)(he)可持續因素(su)的(de)(de)(de)綠(lv)(lv)色環(huan)保新建(jian)項目(mu)的(de)(de)(de)合(he)理選(xuan)擇。在(zai)美國(guo)使用低(di)煙(yan)無鹵(lu)電(dian)(dian)纜(lan)(lan)(lan)可能(neng)會(hui)滿足(zu)美國(guo)綠(lv)(lv)色建(jian)筑委員會(hui)LEED(Leadership in Energy and Environmental Design)綠(lv)(lv)色建(jian)筑倡(chang)議的(de)(de)(de)項目(mu)信貸條件。目(mu)前(qian)電(dian)(dian)纜(lan)(lan)(lan)產品除使用金屬(shu)導體外,重要組成(cheng)(cheng)是聚(ju)(ju)合(he)物材料(liao)。幾十年來(lai),電(dian)(dian)纜(lan)(lan)(lan)的(de)(de)(de)絕緣和(he)(he)護(hu)(hu)套材料(liao)中(zhong)通常會(hui)添(tian)加溴(xiu)化(hua)物等鹵(lu)化(hua)成(cheng)(cheng)分(fen)來(lai)改善阻燃特性(xing)。絕緣和(he)(he)護(hu)(hu)套所使用的(de)(de)(de)聚(ju)(ju)氯乙(yi)烯(xi)(PVC),氟(fu)化(hua)乙(yi)烯(xi)丙烯(xi)和(he)(he)氯化(hua)聚(ju)(ju)乙(yi)烯(xi)都含有(you)(you)鹵(lu)素(su)。其(qi)他(ta)用于電(dian)(dian)纜(lan)(lan)(lan)中(zhong)的(de)(de)(de)化(hua)合(he)物也有(you)(you)可能(neng)含有(you)(you)其(qi)他(ta)鹵(lu)化(hua)成(cheng)(cheng)分(fen)的(de)(de)(de)樹脂(zhi)、添(tian)加劑(ji)和(he)(he)色母(mu)。
造成對于LSHF電(dian)(dian)纜(lan)混亂理(li)解的重要原因是兩個***常用的傳(chuan)統標準:IEC 60754-1“電(dian)(dian)纜(lan)材料燃(ran)燒時產生的氣體(ti)(ti)測(ce)試(shi),:鹵酸(suan)氣體(ti)(ti)含量的測(ce)定”IEC 60754-2 “電(dian)(dian)纜(lan)材質燃(ran)燒產生氣體(ti)(ti)檢(jian)測(ce),第2部分(fen):酸(suan)度(du)(通(tong)過測(ce)量pH值)和(he)導電(dian)(dian)率的測(ce)定”
這兩本(ben)標(biao)準(zhun)均未對鹵(lu)素(su)的(de)(de)基本(ben)元(yuan)素(su),即,氟、氯、溴(xiu)、碘(dian)、砹的(de)(de)含量(liang)進行(xing)測試(shi)(shi),但是每個(ge)標(biao)準(zhun)都定義(yi)了對由測試(shi)(shi)材料產(chan)生的(de)(de)氫鹵(lu)酸氣體進行(xing)測試(shi)(shi)的(de)(de)方法,氫鹵(lu)酸氣體來自于上述五種鹵(lu)族元(yuan)素(su)。這些標(biao)準(zhun)沒有(you)明(ming)確提出鹵(lu)素(su)的(de)(de)百分(fen)比(bi)或百分(fen)率水平要求(qiu)。且IEC 60754-2中,pH值和電導率限制被(bei)定義(yi)為“建議(yi)性(xing)(xing)”要求(qiu),并(bing)非“規(gui)范性(xing)(xing)”要求(qiu)。
此外,術語“低煙無鹵(LSHF)”包含兩個獨立的產品特性。很多時候,人們火災中遇難的原因大多是被煙霧窒息嗆死。前面講到的是電纜里材料的“無鹵”,也就是說對每一個可燃材料所釋放出的煙霧要求低毒性。另外一個特性“低煙”則需要考量所釋放的煙霧量,這一特性需要在整體電纜上評估。近幾年已有以下一系列***公認的IEC標準明確統一電纜產品和材料中低煙無鹵特性的要求。

絕緣(yuan)受潮:由(you)于無(wu)(wu)鹵電(dian)(dian)(dian)(dian)子(zi)(zi)線(xian)(xian)路(lu)施工工藝差,濕(shi)氣(qi)侵入電(dian)(dian)(dian)(dian)子(zi)(zi)線(xian)(xian)路(lu)內部(bu),或無(wu)(wu)鹵電(dian)(dian)(dian)(dian)子(zi)(zi)線(xian)(xian)路(lu)內保護(hu)層(ceng)(ceng)損壞,濕(shi)氣(qi)進入無(wu)(wu)鹵電(dian)(dian)(dian)(dian)子(zi)(zi)線(xian)(xian)路(lu);鉛包電(dian)(dian)(dian)(dian)纜敷設(she)在震源周(zhou)圍(wei),因長期(qi)振動(dong)而(er)疲勞(lao)開(kai)裂,無(wu)(wu)鹵電(dian)(dian)(dian)(dian)子(zi)(zi)線(xian)(xian)路(lu)的外皮被(bei)腐蝕并(bing)漂浮,由(you)于制造質(zhi)量不好,鉛包上有小(xiao)孔或裂紋;鑒于這(zhe)些現象,應加強無(wu)(wu)鹵電(dian)(dian)(dian)(dian)子(zi)(zi)線(xian)(xian)路(lu)外層(ceng)(ceng)的維護(hu),并(bing)按期(qi)在外保護(hu)層(ceng)(ceng)上涂一(yi)層(ceng)(ceng)瀝青(qing)。過電(dian)(dian)(dian)(dian)壓(ya):無(wu)(wu)鹵電(dian)(dian)(dian)(dian)子(zi)(zi)線(xian)(xian)路(lu)絕緣(yuan)層(ceng)(ceng)因大氣(qi)過電(dian)(dian)(dian)(dian)壓(ya)或內部(bu)過電(dian)(dian)(dian)(dian)壓(ya)而(er)擊(ji)穿,特別是(shi)系(xi)統內部(bu)過電(dian)(dian)(dian)(dian)壓(ya)會導致多根電(dian)(dian)(dian)(dian)纜同時擊(ji)穿,在這(zhe)方面,應安裝(zhuang)避雷器。
絕(jue)緣(yuan)老化:在無鹵(lu)電(dian)子(zi)線(xian)路(lu)的長期運行過(guo)程中(zhong),由(you)于散熱不(bu)良或過(guo)載,絕(jue)緣(yuan)材料的電(dian)氣和(he)機(ji)械功能(neng)變差,絕(jue)緣(yuan)層變脆(cui)或斷裂(lie),如果是這種(zhong)情況,應定期對無鹵(lu)素電(dian)子(zi)線(xian)路(lu)進(jin)行預防(fang)性耐壓測試,在無鹵(lu)電(dian)子(zi)線(xian)路(lu)絕(jue)緣(yuan)降(jiang)低不(bu)符合安全運行條件,應更換新電(dian)纜。
