江西聚錄乙烯電線廠家我(wo)國(guo)阻燃和耐(nai)火(huo)電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜(lan)的(de)研究(jiu)開(kai)發(fa)始于1982年(nian)。經過5年(nian)時間，即198年(nian)，許多電(dian)(dian)(dian)纜(lan)廠(chang)家已(yi)投(tou)入生產并為用(yong)(yong)(yong)戶所認同。針對當時對燃燒(shao)特性的(de)命名(ming)和型(xing)(xing)(xing)(xing)號(hao)(hao)比較混亂的(de)情況(kuang)，筆者提出(chu)以(yi)燃燒(shao)試驗方(fang)法相對應(ying)的(de)電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜(lan)燃燒(shao)特性，對防火(huo)電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜(lan)進(jin)行分類，用(yong)(yong)(yong)漢語拼音的(de)首位字(zi)母定型(xing)(xing)(xing)(xing)作為相應(ying)普(pu)通(tong)電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜(lan)型(xing)(xing)(xing)(xing)號(hao)(hao)的(de)前(qian)綴(zhui)。其中阻燃電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜(lan)類的(de)型(xing)(xing)(xing)(xing)號(hao)(hao)ZR和耐(nai)火(huo)電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜(lan)類的(de)型(xing)(xing)(xing)(xing)號(hao)(hao)NH已(yi)沿用(yong)(yong)(yong)至今。隨著防火(huo)電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜(lan)在開(kai)發(fa)研究(jiu)中所取得(de)的(de)許多新(xin)進(jin)展(zhan)，原有(you)型(xing)(xing)(xing)(xing)號(hao)(hao)已(yi)不敷使用(yong)(yong)(yong)。加(jia)之投(tou)產廠(chang)家越(yue)來越(yue)多，在制訂企業標(biao)準時，對有(you)關型(xing)(xing)(xing)(xing)號(hao)(hao)各取所需，又(you)造成新(xin)的(de)混亂。最突出(chu)的(de)表現是，電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜(lan)的(de)燃燒(shao)特性相同，但(dan)名(ming)稱和型(xing)(xing)(xing)(xing)號(hao)(hao)卻不同。業內及用(yong)(yong)(yong)戶強烈要求(qiu)改變(bian)這個(ge)狀況(kuang)，希望(wang)對型(xing)(xing)(xing)(xing)號(hao)(hao)予以(yi)統一。為此，本文提出(chu)防火(huo)電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜(lan)型(xing)(xing)(xing)(xing)號(hao)(hao)的(de)編(bian)制方(fang)法，供日后(hou)編(bian)制企業標(biao)準或行業標(biao)準參考(kao)。

聚錄乙烯電線光(guang)伏新政已出臺近兩個(ge)月，很多企(qi)業紛紛選擇(ze)開拓海(hai)外(wai)市(shi)場(chang)，至(zhi)2020年累計市(shi)場(chang)容量將(jiang)達(da)5900億(yi)美元(yuan)，其中約4000億(yi)美元(yuan)將(jiang)來(lai)自(zi)于項目融資(zi)，海(hai)外(wai)市(shi)場(chang)復合增長率(lv)高達(da)16%。但海(hai)外(wai)“風景(jing)”雖(sui)好，投資(zi)卻(que)有風險(xian)，海(hai)外(wai)出行需謹(jin)慎。風險(xian)是既(ji)存的事實，遇到風險(xian)也不能(neng)停滯不前(qian)，所以對于海(hai)外(wai)市(shi)場(chang)風險(xian)把控(kong)是重要手(shou)段。
