專業生產花線電(dian)纜(lan)老化(hua)原因(yin)：外(wai)力的(de)(de)(de)(de)損(sun)(sun)傷(shang)。由近幾年的(de)(de)(de)(de)數據分析來看，尤其是(shi)在(zai)經濟高速發展中的(de)(de)(de)(de)上海，現在(zai)的(de)(de)(de)(de)大多數電(dian)纜(lan)故障(zhang)(zhang)都是(shi)因(yin)為機械(xie)損(sun)(sun)傷(shang)引起的(de)(de)(de)(de)。譬如(ru)：電(dian)纜(lan)在(zai)敷設安裝的(de)(de)(de)(de)過程中不按(an)照正常規(gui)范施(shi)工，容易造成(cheng)機械(xie)損(sun)(sun)傷(shang)；在(zai)直埋電(dian)纜(lan)上建造施(shi)工也特(te)別容易將(jiang)運行中的(de)(de)(de)(de)電(dian)纜(lan)損(sun)(sun)傷(shang)等。有時(shi)如(ru)果損(sun)(sun)傷(shang)不嚴(yan)重(zhong)，要(yao)經過數年才會(hui)導(dao)致(zhi)損(sun)(sun)傷(shang)部位徹底(di)擊(ji)穿形成(cheng)故障(zhang)(zhang)，有時(shi)破壞相對比較嚴(yan)重(zhong)的(de)(de)(de)(de)可能會(hui)發生(sheng)短路故障(zhang)(zhang)，直接影響到用(yong)電(dian)單(dan)位的(de)(de)(de)(de)安全。

和其它花線礦(kuang)物(wu)絕緣電(dian)(dian)(dian)(dian)纜(lan)相(xiang)比較，YTTW礦(kuang)物(wu)絕緣電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)制(zhi)作(zuo)方式采(cai)用(yong)的(de)(de)(de)(de)是扎紋銅(tong)金屬(shu)護套加上(shang)無機絕緣材料(liao)相(xiang)互(hu)結(jie)合，然(ran)后利(li)用(yong)銅(tong)帶縱(zong)包(bao)的(de)(de)(de)(de)無縫焊機的(de)(de)(de)(de)技術代(dai)替之前(qian)的(de)(de)(de)(de)技術，使電(dian)(dian)(dian)(dian)纜(lan)長(chang)(chang)度(du)不(bu)再受之前(qian)的(de)(de)(de)(de)長(chang)(chang)度(du)限(xian)制(zhi)，使用(yong)該方式可以(yi)將(jiang)制(zhi)作(zuo)的(de)(de)(de)(de)長(chang)(chang)度(du)延伸到2000米左右。減少了(le)(le)同等(deng)長(chang)(chang)度(du)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)纜(lan)中間連(lian)接頭，增加了(le)(le)電(dian)(dian)(dian)(dian)氣穩定(ding)性(xing)，也相(xiang)應的(de)(de)(de)(de)減少了(le)(le)一定(ding)的(de)(de)(de)(de)工(gong)作(zuo)時間。而且YTTW礦(kuang)物(wu)絕緣電(dian)(dian)(dian)(dian)纜(lan)因(yin)為柔性(xing)程(cheng)度(du)上(shang)比傳(chuan)統電(dian)(dian)(dian)(dian)纜(lan)柔韌性(xing)好(hao)很多，所(suo)以(yi)在使用(yong)或者(zhe)運(yun)輸的(de)(de)(de)(de)時候都比較方便，不(bu)再受限(xian)于外(wai)(wai)部硬包(bao)裝，可以(yi)適(shi)當的(de)(de)(de)(de)根(gen)據(ju)外(wai)(wai)部環境(jing)的(de)(de)(de)(de)地(di)形(xing)(xing)所(suo)變化，很好(hao)的(de)(de)(de)(de)應用(yong)在更多的(de)(de)(de)(de)復雜地(di)形(xing)(xing)。并且因(yin)為采(cai)取的(de)(de)(de)(de)技術原因(yin)，完整(zheng)(zheng)的(de)(de)(de)(de)外(wai)(wai)包(bao)裝將(jiang)整(zheng)(zheng)個核(he)心部分(fen)包(bao)裹在里(li)面，避免了(le)(le)核(he)心部分(fen)受潮的(de)(de)(de)(de)情(qing)況。

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花線延(yan)伸1000米(mi)都是沒有問題的，而剛性BTTZ電纜需要考慮(lv)過長(chang)的電纜不易存放，并且(qie)不容易生產制作(zuo)，所以(yi)YTTW礦(kuang)物電纜能夠避免長(chang)度(du)(du)要求(qiu)的規(gui)范，不用(yong)擔心使(shi)用(yong)的時候長(chang)度(du)(du)不足使(shi)用(yong)接口。

具有購買力的電線電纜市場需求減少。由于全球市場經濟不景氣，我國花線電(dian)線電(dian)纜(lan)(lan)(lan)(lan)市(shi)場也受(shou)到(dao)(dao)重(zhong)(zhong)創，需求量一度下落。但(dan)是進入2018年(nian)，市(shi)場由(you)(you)于受(shou)到(dao)(dao)智網及(ji)寬帶工(gong)程建設(she)有(you)利(li)(li)促(cu)進，目前(qian)正在(zai)逐步恢復當中，但(dan)對(dui)電(dian)纜(lan)(lan)(lan)(lan)行(xing)業(ye)(ye)(ye)的(de)利(li)(li)潤緩(huan)解(jie)作用較(jiao)(jiao)為有(you)限。原(yuan)材價格(ge)(ge)不(bu)穩(wen)定，嚴重(zhong)(zhong)積壓電(dian)纜(lan)(lan)(lan)(lan)行(xing)業(ye)(ye)(ye)的(de)利(li)(li)潤。電(dian)纜(lan)(lan)(lan)(lan)行(xing)業(ye)(ye)(ye)的(de)特(te)點是料(liao)重(zhong)(zhong)工(gong)輕(qing)利(li)(li)薄，當原(yuan)材價格(ge)(ge)上漲時，電(dian)纜(lan)(lan)(lan)(lan)企(qi)(qi)(qi)(qi)業(ye)(ye)(ye)購買原(yuan)材將造成(cheng)銀(yin)根吃緊(jin)，資金周轉(zhuan)緩(huan)慢(man)。而當原(yuan)材價格(ge)(ge)下跌，電(dian)纜(lan)(lan)(lan)(lan)企(qi)(qi)(qi)(qi)業(ye)(ye)(ye)又回因為來不(bu)及(ji)消化原(yuan)材，而造成(cheng)出廠價急速(su)下跌。兩(liang)者間(jian)的(de)兩(liang)者之間(jian)的(de)“剪刀差(cha)”與“時間(jian)差(cha)”嚴重(zhong)(zhong)擠壓了(le)電(dian)纜(lan)(lan)(lan)(lan)企(qi)(qi)(qi)(qi)業(ye)(ye)(ye)的(de)盈(ying)利(li)(li)空間(jian)。目前(qian)行(xing)業(ye)(ye)(ye)普遍比(bi)較(jiao)(jiao)認可的(de)說法是，原(yuan)材價格(ge)(ge)原(yuan)材料(liao)價格(ge)(ge)每上漲5%，電(dian)纜(lan)(lan)(lan)(lan)企(qi)(qi)(qi)(qi)業(ye)(ye)(ye)的(de)相對(dui)利(li)(li)潤則將減少4%。銀(yin)行(xing)貸款利(li)(li)息的(de)不(bu)斷增加，同樣給電(dian)纜(lan)(lan)(lan)(lan)企(qi)(qi)(qi)(qi)業(ye)(ye)(ye)的(de)利(li)(li)潤空間(jian)造成(cheng)重(zhong)(zhong)大(da)影(ying)響。由(you)(you)于目前(qian)我國的(de)電(dian)纜(lan)(lan)(lan)(lan)企(qi)(qi)(qi)(qi)業(ye)(ye)(ye)基本(ben)都是民(min)營企(qi)(qi)(qi)(qi)業(ye)(ye)(ye)，因此即使(shi)比(bi)較(jiao)(jiao)幸運能夠(gou)帶到(dao)(dao)款，但(dan)是利(li)(li)率一般也要(yao)上浮40%左后，何(he)況有(you)眾多企(qi)(qi)(qi)(qi)業(ye)(ye)(ye)根本(ben)就融(rong)不(bu)到(dao)(dao)資。融(rong)資難的(de)問題直(zhi)接(jie)造成(cheng)我國整個(ge)電(dian)纜(lan)(lan)(lan)(lan)行(xing)業(ye)(ye)(ye)的(de)資金回籠周期(qi)變慢(man)，三角債盛行(xing)。
