阻燃的花線電(dian)纜(lan)(lan)老化原因：外力的損(sun)(sun)(sun)傷(shang)(shang)。由(you)近幾年的數據分(fen)析(xi)來看(kan)，尤其是在(zai)經濟高速發(fa)展中(zhong)的上海，現在(zai)的大多數電(dian)纜(lan)(lan)故障都是因為機械損(sun)(sun)(sun)傷(shang)(shang)引(yin)起(qi)的。譬如(ru)：電(dian)纜(lan)(lan)在(zai)敷設安裝的過程(cheng)中(zhong)不按照正常(chang)規范施工(gong)，容易造成機械損(sun)(sun)(sun)傷(shang)(shang)；在(zai)直埋(mai)電(dian)纜(lan)(lan)上建(jian)造施工(gong)也特別容易將運(yun)行(xing)中(zhong)的電(dian)纜(lan)(lan)損(sun)(sun)(sun)傷(shang)(shang)等。有(you)時(shi)(shi)如(ru)果(guo)損(sun)(sun)(sun)傷(shang)(shang)不嚴重(zhong)，要經過數年才會(hui)導(dao)致損(sun)(sun)(sun)傷(shang)(shang)部位徹底擊穿形成故障，有(you)時(shi)(shi)破(po)壞相對比較嚴重(zhong)的可能(neng)會(hui)發(fa)生短路故障，直接(jie)影響到用電(dian)單位的安全。
