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的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,为电流致热型电缆火灾的防治提供了基础数据。A study on the aging life of the cable insulation material caused by heat has been conducted by using heat analysis method. A calculation formula of the aging life of the cable insulation material has been derived. The aging lives of the insulation material under different carrying currents are compared, and different function relationships between the aging life of the insullation material and the carrying current are given. It provids basic dada for preventing cable fire due to heat caused by currents.
