| Abstract: | 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. |
