摘　　要：利用热分析技术,对电缆绝缘材料的热老化寿命进行了研究,得到了电缆绝缘材料热老化寿命的计算公式。在不同载流量下,对电缆绝缘材料热老化寿命进行了比较,给出了电缆热老化寿命与载流量的函数关系,为电流致热型线缆火灾的防治提供了基础数据。A hot and aging life expectancy study of the cable insulation material has been conducted by using hot analytical method. A calculation formula of the cable insulation material＇ s hot and aging life expectancy has been formed. The cable＇ s hot and aging life expectancy at different carrying current were compared, the function of cable＇ s hot and aging life in different carrying current has been given. It provided basic dada for preventing cable fire caused by over curren.
