鋁芯電纜光(guang)伏新政已(yi)出臺近兩個月，很多企(qi)業紛紛選(xuan)擇開拓海(hai)外(wai)(wai)(wai)(wai)市(shi)場，至2020年累計市(shi)場容量將達(da)(da)5900億美元(yuan)，其中約(yue)4000億美元(yuan)將來自于項目(mu)融資，海(hai)外(wai)(wai)(wai)(wai)市(shi)場復合增長率高達(da)(da)16%。但(dan)海(hai)外(wai)(wai)(wai)(wai)“風(feng)(feng)景”雖好，投資卻有風(feng)(feng)險(xian)，海(hai)外(wai)(wai)(wai)(wai)出行需謹慎。風(feng)(feng)險(xian)是(shi)既存的事實，遇到風(feng)(feng)險(xian)也(ye)不能(neng)停滯不前(qian)，所以對于海(hai)外(wai)(wai)(wai)(wai)市(shi)場風(feng)(feng)險(xian)把(ba)控是(shi)重要手(shou)段。

阻燃的鋁芯電纜電(dian)(dian)纜老化(hua)原因：外(wai)力(li)的(de)(de)損傷(shang)(shang)(shang)。由(you)近(jin)幾年(nian)的(de)(de)數據(ju)分析來看，尤其是在經濟高速發展中(zhong)的(de)(de)上海(hai)，現(xian)在的(de)(de)大多(duo)數電(dian)(dian)纜故障(zhang)都是因為機(ji)械損傷(shang)(shang)(shang)引(yin)起的(de)(de)。譬如：電(dian)(dian)纜在敷設安裝的(de)(de)過程中(zhong)不(bu)按照正常規范施(shi)(shi)工(gong)，容易(yi)造成機(ji)械損傷(shang)(shang)(shang)；在直(zhi)埋電(dian)(dian)纜上建造施(shi)(shi)工(gong)也特別(bie)容易(yi)將(jiang)運行中(zhong)的(de)(de)電(dian)(dian)纜損傷(shang)(shang)(shang)等。有(you)時(shi)如果損傷(shang)(shang)(shang)不(bu)嚴(yan)重，要(yao)經過數年(nian)才會(hui)導(dao)致損傷(shang)(shang)(shang)部(bu)位(wei)徹底擊穿形成故障(zhang)，有(you)時(shi)破壞相對比(bi)較嚴(yan)重的(de)(de)可(ke)能會(hui)發生短路故障(zhang)，直(zhi)接影響到用電(dian)(dian)單位(wei)的(de)(de)安全。
