北京阻燃的阻燃花線廠家近年來，伴隨著我(wo)國(guo)(guo)經濟的(de)(de)快速增長(chang)以(yi)(yi)(yi)及工業化(hua)、城鎮化(hua)進程的(de)(de)加快，我(wo)國(guo)(guo)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)行(xing)業發展(zhan)迅猛，?早于?2011?年我(wo)國(guo)(guo)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)制造業的(de)(de)產(chan)(chan)值(zhi)(zhi)就(jiu)已超過美(mei)國(guo)(guo)，躍居全球第一(yi)，國(guo)(guo)內市場產(chan)(chan)品(pin)品(pin)種滿足率達(da)?95%以(yi)(yi)(yi)上(shang)(shang)。但(dan)現階(jie)段粗放式生產(chan)(chan)仍是我(wo)國(guo)(guo)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)行(xing)業的(de)(de)主(zhu)(zhu)流，仍然(ran)存在(zai)較為(wei)突出的(de)(de)結構失衡問題，即普(pu)通(tong)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)產(chan)(chan)品(pin)供過于求，而(er)高端產(chan)(chan)品(pin)供不(bu)應求。我(wo)國(guo)(guo)是世界電(dian)(dian)纜(lan)(lan)第一(yi)制造大國(guo)(guo)，但(dan)產(chan)(chan)業發展(zhan)還(huan)不(bu)成熟、重量(liang)(liang)輕質(zhi)(zhi)，產(chan)(chan)業集中度低，科研投入(ru)不(bu)足，創新能力(li)較弱，與國(guo)(guo)外(wai)先進國(guo)(guo)家(jia)相比仍存在(zai)較大差距(ju)，提升質(zhi)(zhi)量(liang)(liang)將成為(wei)行(xing)業今后發展(zhan)的(de)(de)主(zhu)(zhu)要方向。國(guo)(guo)際上(shang)(shang)對電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)產(chan)(chan)業的(de)(de)產(chan)(chan)量(liang)(liang)及消費量(liang)(liang)的(de)(de)分析，一(yi)般以(yi)(yi)(yi)銅芯絕緣電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)為(wei)主(zhu)(zhu)，并分為(wei)動力(li)電(dian)(dian)纜(lan)(lan)、通(tong)信電(dian)(dian)纜(lan)(lan)和繞(rao)組線(xian)三大類(lei)(與國(guo)(guo)內習慣(guan)分類(lei)有所不(bu)同)，采(cai)用以(yi)(yi)(yi)美(mei)元為(wei)價(jia)值(zhi)(zhi)計量(liang)(liang)單位(wei)或以(yi)(yi)(yi)銅導體(ti)消耗(hao)量(liang)(liang)(重量(liang)(liang))為(wei)主(zhu)(zhu)要統計單位(wei)，由于價(jia)值(zhi)(zhi)量(liang)(liang)的(de)(de)數據包含了不(bu)同時期(qi)的(de)(de)通(tong)貨膨(peng)脹率以(yi)(yi)(yi)及材料價(jia)格的(de)(de)變動，因此采(cai)用銅導體(ti)消耗(hao)量(liang)(liang)的(de)(de)分析排(pai)除了導體(ti)價(jia)格變動的(de)(de)因素，相對而(er)言比較接近實際的(de)(de)變化(hua)趨勢。

北京阻燃花線廠家我國(guo)阻(zu)燃(ran)(ran)(ran)和(he)(he)耐火(huo)(huo)電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)研(yan)究(jiu)開發(fa)始于1982年。經過5年時(shi)間，即198年，許(xu)多(duo)電(dian)(dian)(dian)纜(lan)廠家已投入生產(chan)并為(wei)用戶(hu)所(suo)認(ren)同。針對(dui)當(dang)時(shi)對(dui)燃(ran)(ran)(ran)燒特性的(de)(de)(de)命名和(he)(he)型號(hao)比較(jiao)混亂的(de)(de)(de)情況，筆(bi)者提出(chu)以(yi)燃(ran)(ran)(ran)燒試(shi)驗方法(fa)相對(dui)應的(de)(de)(de)電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜(lan)燃(ran)(ran)(ran)燒特性，對(dui)防火(huo)(huo)電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜(lan)進行分類(lei)，用漢(han)語拼音的(de)(de)(de)首位字母定型作為(wei)相應普(pu)通電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜(lan)型號(hao)的(de)(de)(de)前綴。其中(zhong)阻(zu)燃(ran)(ran)(ran)電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜(lan)類(lei)的(de)(de)(de)型號(hao)ZR和(he)(he)耐火(huo)(huo)電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜(lan)類(lei)的(de)(de)(de)型號(hao)NH已沿(yan)用至今。隨著防火(huo)(huo)電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜(lan)在開發(fa)研(yan)究(jiu)中(zhong)所(suo)取得的(de)(de)(de)許(xu)多(duo)新進展，原有型號(hao)已不(bu)敷使用。加之投產(chan)廠家越(yue)來(lai)越(yue)多(duo)，在制訂企業(ye)(ye)標準時(shi)，對(dui)有關型號(hao)各取所(suo)需(xu)，又造(zao)成新的(de)(de)(de)混亂。最突出(chu)的(de)(de)(de)表(biao)現是(shi)，電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)燃(ran)(ran)(ran)燒特性相同，但名稱和(he)(he)型號(hao)卻不(bu)同。業(ye)(ye)內及用戶(hu)強烈要求改變這個狀況，希望對(dui)型號(hao)予以(yi)統一。為(wei)此，本文提出(chu)防火(huo)(huo)電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜(lan)型號(hao)的(de)(de)(de)編(bian)制方法(fa)，供(gong)日后(hou)編(bian)制企業(ye)(ye)標準或行業(ye)(ye)標準參(can)考。
