摘　　要：通过南海海洋大气环境试验对4种不同护套的电缆进行了老化研究,采用外观、硬度和机械性能检测项目,研究了护套在户外和棚下不同周期大气暴露试验后的性能劣化规律和外观变化趋势,并进行对比分析。结果表明,在南海海洋大气环境中,PVC、PO、XLP护套样品的耐侯性较好;PCP护套样品的耐侯性最差。The aging behaviors of 4 kinds of different sheathed cables subject to South China marine atmospheric environment test were investigated. Based on the appearance, hardness and mechanical properties testing, the performance degradation and appearance changing trends of the sheaths under different atmospheric exposure test cycle in the outdoor and shed were analyzed and compared. The results showed that, in the South China marine atmospheric environment, the weathering resistance of PVC, PO and XLPO sheath samples was good, but the weathering resistance of PCP sheath samples was the worst.
