貴州銅塑線批發我(wo)國阻燃(ran)和耐火電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)的(de)(de)(de)研究開發始于1982年。經過5年時(shi)間，即198年，許多(duo)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)廠家(jia)已投(tou)入生產并為(wei)用(yong)(yong)(yong)戶所認(ren)同(tong)。針對(dui)(dui)(dui)(dui)當(dang)時(shi)對(dui)(dui)(dui)(dui)燃(ran)燒特(te)性的(de)(de)(de)命名(ming)和型(xing)號(hao)(hao)比較混(hun)亂的(de)(de)(de)情(qing)況，筆(bi)者提出以燃(ran)燒試驗方法(fa)相(xiang)(xiang)對(dui)(dui)(dui)(dui)應的(de)(de)(de)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)燃(ran)燒特(te)性，對(dui)(dui)(dui)(dui)防火電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)進行分類(lei)，用(yong)(yong)(yong)漢語(yu)拼音的(de)(de)(de)首位字(zi)母(mu)定型(xing)作為(wei)相(xiang)(xiang)應普通電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)型(xing)號(hao)(hao)的(de)(de)(de)前綴(zhui)。其中阻燃(ran)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)類(lei)的(de)(de)(de)型(xing)號(hao)(hao)ZR和耐火電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)類(lei)的(de)(de)(de)型(xing)號(hao)(hao)NH已沿用(yong)(yong)(yong)至今。隨著(zhu)防火電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)在開發研究中所取得的(de)(de)(de)許多(duo)新進展，原(yuan)有型(xing)號(hao)(hao)已不敷使用(yong)(yong)(yong)。加之投(tou)產廠家(jia)越來越多(duo)，在制(zhi)(zhi)訂企業(ye)標(biao)準時(shi)，對(dui)(dui)(dui)(dui)有關型(xing)號(hao)(hao)各取所需，又造成新的(de)(de)(de)混(hun)亂。最突出的(de)(de)(de)表現(xian)是(shi)，電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)的(de)(de)(de)燃(ran)燒特(te)性相(xiang)(xiang)同(tong)，但名(ming)稱(cheng)和型(xing)號(hao)(hao)卻(que)不同(tong)。業(ye)內及用(yong)(yong)(yong)戶強烈(lie)要求改(gai)變這個狀況，希望對(dui)(dui)(dui)(dui)型(xing)號(hao)(hao)予以統一。為(wei)此，本文提出防火電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)型(xing)號(hao)(hao)的(de)(de)(de)編制(zhi)(zhi)方法(fa)，供日后編制(zhi)(zhi)企業(ye)標(biao)準或行業(ye)標(biao)準參考。
