Hi PF
Is it possible to perform accelerated lifetime test of thermal ageing on power cables?
Let's assume that the cable manufacturer guarantees a service life time of 20 years at max operation temperature 90 [degC]. Is it possible to estimate the expected life time of a cable if I choose to operate my cable above the 90 [degC] let's say 100 [degC]. Maybe the expected life time could be calculated using Arrhenius equation?
Are there any IEC standards that deal with this? That i can use to estimate the life time of a cable
I know that the cable manufacturer do accelerated lifetime voltage test on cables where they test breakdown at 4xU0 (4 times rated voltage) at 4 hours. Does they perform similar tests for thermal degradation of the insulation material?
