船用電纜的使用壽命由哪些因素決定?

摘要:
   船用電纜的質量好固然好,但是用戶如果將其買回家,不注重維護,其使用壽命也會縮短的。因此,電線船用電纜廠家建議大家要合理正確使用船用電纜,要記得給船用電纜好的維護。船用電纜的使用壽命往往取決于多種因素,因為再好的船用電纜,經過時間和外部環境因素等都會承受不住的;那么船用電纜的使用壽命到底由哪些因素決定呢?
   化學腐蝕:船用電纜直接埋在有酸堿作用的地區,往往會造成船用電纜的鎧裝、鉛皮或外護層被腐蝕,保護層因長期遭受化學腐蝕或電解腐蝕,致使保護層失效,絕緣降低,也會導致船用電纜故障。
   絕緣受潮:這種情況也很常見,一般發生在直埋或排管里的船用電纜接頭處。比如:船用電纜接頭制作不合格和在潮濕的氣候條件下做接頭,會使接頭進水或混入水蒸氣,時間久r在電場作用下形成水樹枝,逐漸損害船用電纜的絕緣強度而造成故障。
   環境和溫度:船用電纜所處的外界環境和熱源也會造成船用電纜溫度過高、絕緣擊穿,甚至爆炸起火。
