1. 看電纜電線長度：福建性價比銅芯線國(guo)家標準(zhun)規定(ding)，電(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)纜每卷(juan)100米(mi)，計量誤差不(bu)大(da)于0.5%，也就(jiu)是(shi)每卷(juan)線(xian)的(de)(de)(de)長(chang)度為(wei)100±0.5米(mi)，但(dan)(dan)是(shi)有(you)(you)些(xie)(xie)商家標注的(de)(de)(de)是(shi)100±20米(mi)，但(dan)(dan)實(shi)際(ji)上，卻只有(you)(you)80米(mi)左(zuo)右。2. 看(kan)電(dian)(dian)(dian)(dian)(dian)阻(zu)值：電(dian)(dian)(dian)(dian)(dian)阻(zu)值超(chao)標的(de)(de)(de)話(hua)，電(dian)(dian)(dian)(dian)(dian)線(xian)就(jiu)容(rong)易出(chu)(chu)現溫度過高、老(lao)化(hua)的(de)(de)(de)危險(xian)，而(er)(er)且如(ru)果電(dian)(dian)(dian)(dian)(dian)線(xian)短(duan)路的(de)(de)(de)話(hua)，還(huan)會引(yin)發(fa)火災。并(bing)且電(dian)(dian)(dian)(dian)(dian)阻(zu)值超(chao)標，還(huan)增加(jia)(jia)傳輸(shu)電(dian)(dian)(dian)(dian)(dian)量時(shi)的(de)(de)(de)消(xiao)耗(hao)，增加(jia)(jia)電(dian)(dian)(dian)(dian)(dian)費，所以，我們在選擇時(shi)，一定(ding)要留意這(zhe)一點。3.看(kan)原材料：純銅(tong)(tong)芯的(de)(de)(de)材料導(dao)電(dian)(dian)(dian)(dian)(dian)性(xing)好，而(er)(er)且不(bu)易老(lao)化(hua)，更加(jia)(jia)耐用(yong)(yong)，也減(jian)少(shao)了故障(zhang)發(fa)生。但(dan)(dan)是(shi)有(you)(you)些(xie)(xie)商家，會在銅(tong)(tong)材質(zhi)中添加(jia)(jia)一些(xie)(xie)雜質(zhi)銅(tong)(tong)、回收銅(tong)(tong)，還(huan)有(you)(you)的(de)(de)(de)劣質(zhi)產品通過降低(di)銅(tong)(tong)芯實(shi)際(ji)截面(mian)積，來減(jian)少(shao)銅(tong)(tong)材質(zhi)的(de)(de)(de)用(yong)(yong)量，這(zhe)樣容(rong)易導(dao)致電(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)纜用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)過程中發(fa)熱，損壞外邊的(de)(de)(de)絕緣層塑料，容(rong)易讓電(dian)(dian)(dian)(dian)(dian)線(xian)老(lao)化(hua)，導(dao)致出(chu)(chu)現漏電(dian)(dian)(dian)(dian)(dian)、短(duan)路的(de)(de)(de)問題。

福建銅芯線廠家我(wo)國阻燃(ran)(ran)和(he)(he)耐(nai)火(huo)(huo)電(dian)線(xian)(xian)(xian)電(dian)纜(lan)(lan)(lan)(lan)的(de)研究開發始于1982年。經過(guo)5年時間，即198年，許(xu)多電(dian)纜(lan)(lan)(lan)(lan)廠家已投入生產并(bing)為用戶所認同。針對(dui)當時對(dui)燃(ran)(ran)燒(shao)特性的(de)命名和(he)(he)型(xing)(xing)號(hao)(hao)(hao)比較混亂的(de)情況(kuang)，筆(bi)者(zhe)提(ti)出以燃(ran)(ran)燒(shao)試驗方法相對(dui)應的(de)電(dian)線(xian)(xian)(xian)電(dian)纜(lan)(lan)(lan)(lan)燃(ran)(ran)燒(shao)特性，對(dui)防(fang)火(huo)(huo)電(dian)線(xian)(xian)(xian)電(dian)纜(lan)(lan)(lan)(lan)進行(xing)分類(lei)，用漢(han)語拼音的(de)首位(wei)字母(mu)定型(xing)(xing)作(zuo)為相應普通電(dian)線(xian)(xian)(xian)電(dian)纜(lan)(lan)(lan)(lan)型(xing)(xing)號(hao)(hao)(hao)的(de)前綴。其中阻燃(ran)(ran)電(dian)線(xian)(xian)(xian)電(dian)纜(lan)(lan)(lan)(lan)類(lei)的(de)型(xing)(xing)號(hao)(hao)(hao)ZR和(he)(he)耐(nai)火(huo)(huo)電(dian)線(xian)(xian)(xian)電(dian)纜(lan)(lan)(lan)(lan)類(lei)的(de)型(xing)(xing)號(hao)(hao)(hao)NH已沿用至今。隨(sui)著防(fang)火(huo)(huo)電(dian)線(xian)(xian)(xian)電(dian)纜(lan)(lan)(lan)(lan)在開發研究中所取得的(de)許(xu)多新(xin)進展，原有(you)型(xing)(xing)號(hao)(hao)(hao)已不(bu)敷使用。加之(zhi)投產廠家越來越多，在制訂企(qi)業(ye)標(biao)準(zhun)時，對(dui)有(you)關(guan)型(xing)(xing)號(hao)(hao)(hao)各(ge)取所需，又(you)造成新(xin)的(de)混亂。最突出的(de)表現是(shi)，電(dian)線(xian)(xian)(xian)電(dian)纜(lan)(lan)(lan)(lan)的(de)燃(ran)(ran)燒(shao)特性相同，但名稱和(he)(he)型(xing)(xing)號(hao)(hao)(hao)卻不(bu)同。業(ye)內及用戶強烈要求改變(bian)這個(ge)狀況(kuang)，希望對(dui)型(xing)(xing)號(hao)(hao)(hao)予以統一。為此，本文提(ti)出防(fang)火(huo)(huo)電(dian)線(xian)(xian)(xian)電(dian)纜(lan)(lan)(lan)(lan)型(xing)(xing)號(hao)(hao)(hao)的(de)編制方法，供日后編制企(qi)業(ye)標(biao)準(zhun)或行(xing)業(ye)標(biao)準(zhun)參考。
