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銅芯電纜延伸1000米都是(shi)沒有問題的(de)，而剛性BTTZ電纜(lan)需要考慮(lv)過長的(de)電纜(lan)不(bu)易存(cun)放，并且不(bu)容易生產制作，所以YTTW礦物(wu)電纜(lan)能(neng)夠避免(mian)長度要求的(de)規范(fan)，不(bu)用擔心使用的(de)時候長度不(bu)足使用接口。

湖北上原材料價格不斷上漲，近幾年行業市場假冒偽劣、粗制濫造、偷工減料、以次充好現象屢禁不止，不僅埋下了巨大的安全隱患，也導致部分依法生產的企業及經銷商步履維艱。同時，外資企業一直稱霸高端市場，擁有的競爭優勢，給國內電線電纜企業造成了巨大的經營壓力。目前，中國線纜企業數量已突破一萬大關，且大部分是民營企業，市場競爭激烈可想而知。線纜產品良莠不齊，質量出現問題與企業自身有很大關系，因此，企業加大原輔材料采購質量控制力度，注重行業技術創新，提升產品質量。另外，亂象叢生的行業市場，不僅僅是銅芯電纜線(xian)(xian)(xian)纜(lan)(lan)企(qi)業(ye)(ye)(ye)自(zi)身原因造(zao)成的(de)(de)，與的(de)(de)政(zheng)治(zhi)體制和經濟發展政(zheng)策缺失也有著莫大的(de)(de)關聯。線(xian)(xian)(xian)纜(lan)(lan)行業(ye)(ye)(ye)要(yao)想突(tu)破迎來新生，就需要(yao)政(zheng)府和企(qi)業(ye)(ye)(ye)共同探討，制定統一的(de)(de)產(chan)品標(biao)準(zhun)、規范質量、統一價(jia)格，以改變(bian)低價(jia)中標(biao)、質量薄弱的(de)(de)市場現狀。行業(ye)(ye)(ye)專家(jia)建議，中國線(xian)(xian)(xian)纜(lan)(lan)企(qi)業(ye)(ye)(ye)不能一味地(di)要(yao)追求量的(de)(de)擴張，更要(yao)注(zhu)重質的(de)(de)提高(gao)，加強在技(ji)術(shu)(shu)、資(zi)金、管理(li)(li)等方(fang)面的(de)(de)合作交流，引入先(xian)進技(ji)術(shu)(shu)和管理(li)(li)理(li)(li)念，使(shi)企(qi)業(ye)(ye)(ye)實力(li)(li)得到(dao)快速提升，增強國際(ji)競(jing)爭力(li)(li)。
