交聯銅電纜光伏(fu)新政已出臺近兩(liang)個月，很多企業(ye)紛紛選擇(ze)開(kai)拓海外(wai)市(shi)(shi)場(chang)，至(zhi)2020年累計(ji)市(shi)(shi)場(chang)容量將達5900億美元，其中約(yue)4000億美元將來自于項(xiang)目(mu)融(rong)資，海外(wai)市(shi)(shi)場(chang)復合增長(chang)率高達16%。但海外(wai)“風(feng)景(jing)”雖(sui)好，投(tou)資卻有風(feng)險，海外(wai)出行(xing)需謹(jin)慎。風(feng)險是既存的事實，遇到風(feng)險也(ye)不能停(ting)滯不前，所以對于海外(wai)市(shi)(shi)場(chang)風(feng)險把控是重要手段。

專業生產交聯銅電纜電(dian)纜(lan)老化原因：外力的(de)(de)(de)損(sun)傷(shang)(shang)。由近幾年的(de)(de)(de)數(shu)據分析來看，尤其是在(zai)(zai)經濟高速(su)發展(zhan)中(zhong)(zhong)(zhong)的(de)(de)(de)上海，現(xian)在(zai)(zai)的(de)(de)(de)大多數(shu)電(dian)纜(lan)故障都(dou)是因為機(ji)械損(sun)傷(shang)(shang)引起的(de)(de)(de)。譬如：電(dian)纜(lan)在(zai)(zai)敷設安裝的(de)(de)(de)過程中(zhong)(zhong)(zhong)不按照正常規(gui)范施工，容(rong)易造成機(ji)械損(sun)傷(shang)(shang)；在(zai)(zai)直(zhi)埋電(dian)纜(lan)上建造施工也特別容(rong)易將(jiang)運行(xing)中(zhong)(zhong)(zhong)的(de)(de)(de)電(dian)纜(lan)損(sun)傷(shang)(shang)等(deng)。有時(shi)如果損(sun)傷(shang)(shang)不嚴(yan)重(zhong)，要經過數(shu)年才會導致損(sun)傷(shang)(shang)部位(wei)(wei)徹(che)底擊穿形(xing)成故障，有時(shi)破壞相對比較嚴(yan)重(zhong)的(de)(de)(de)可能會發生短(duan)路故障，直(zhi)接影響到用(yong)電(dian)單(dan)位(wei)(wei)的(de)(de)(de)安全。
