首先是針對防火特性上，不管是柔性的YTTW礦物電纜還是剛性的BTTZ電纜，兩者的存在都是為了保證電纜在一定的火焰以及高溫下能夠保證電纜的正常運作，所以它們的防火性能都是極為不錯的。但是從高溫的狀態來講，柔性的YTTW礦物電纜能夠承受的極限溫度為1083攝氏度，而剛性BTTZ電纜只有1000攝氏度，并且柔性YTTW礦物電纜能夠在950在1000攝氏度高溫中運行3小時，BTTZ電纜只能維持半小時而已。然后是區分電纜的制作長度，因為工藝特性原因。YTTW礦物電纜因為比較柔和一些，在制作的時候能夠將其長度聚錄乙烯電纜延伸1000米都是(shi)沒有(you)問題的(de)，而(er)剛性(xing)BTTZ電(dian)纜(lan)需要考慮過(guo)長的(de)電(dian)纜(lan)不易存放，并(bing)且不容易生(sheng)產制作，所以(yi)YTTW礦物(wu)電(dian)纜(lan)能夠避免長度要求的(de)規(gui)范，不用(yong)(yong)擔心使用(yong)(yong)的(de)時候長度不足(zu)使用(yong)(yong)接(jie)口。

電線電纜作為國民經濟中最大的配套行業之一，是各產業的基礎，其產品廣泛應用于電力、建筑、民用、通信、船舶、軍工、航空以及石油化工等領域。電線電纜按用途可分為電力電纜、電氣裝備電纜、繞組線、裸電線、通信電纜和電線及電纜配件，從2017年我國電線電纜行業細分市場規模占比情況來看，聚錄乙烯電纜報價電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)占據(ju)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)業(ye)(ye)務(wu)的(de)(de)(de)最大(da)部分(fen)，規模占比35.7%，其次是電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)氣裝備(bei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)、繞組線，分(fen)別占比20%和(he)15.7%。近年來(lai)(lai)，我國(guo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)行(xing)業(ye)(ye)保(bao)持了較(jiao)快發(fa)展勢(shi)頭，作為(wei)國(guo)民經(jing)濟的(de)(de)(de)最重要的(de)(de)(de)支撐(cheng)產業(ye)(ye)之一(yi)(yi)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)行(xing)業(ye)(ye)在(zai)中(zhong)國(guo)有著廣(guang)闊的(de)(de)(de)市(shi)場。根據(ju)近幾年的(de)(de)(de)情(qing)況來(lai)(lai)看，我國(guo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)行(xing)業(ye)(ye)銷(xiao)售收入總體呈現上升(sheng)趨(qu)勢(shi)，其中(zhong)2016年銷(xiao)售收入創新高(gao)達13924億(yi)元(yuan)，2017年電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)銷(xiao)售收入出現小(xiao)幅下降，為(wei)13513億(yi)元(yuan)。隨著我國(guo)對基礎(chu)設施投入的(de)(de)(de)加大(da)，以及新能源、軍工(gong)、海洋工(gong)程、軌道(dao)交通(tong)、特高(gao)壓、智能電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)的(de)(de)(de)發(fa)展得到進一(yi)(yi)步貫徹(che)落(luo)實，市(shi)場對電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)的(de)(de)(de)需求(qiu)在(zai)不(bu)斷增(zeng)強，尤其是在(zai)高(gao)端裝備(bei)用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)方面，未來(lai)(lai)我國(guo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)行(xing)業(ye)(ye)銷(xiao)售收入仍(reng)將進一(yi)(yi)步增(zeng)加。
