Oxygen consumption for PVC、 EPR and CSM as the cable insulation materials after irradiation and thermal aging were measured by using gas chromatograph in order to study the lifetime estimation. Kinetic analysis of experiment data was made. It is found that thermal oxidative reaction is a first-order reaction under the experiment condition in this work. Rate constants were obtained. Comparison with the theoretical calculated data according to Arrhenius equation was also made. It is thought that the simplified Arrhenius equation is not appropriate as the model for lifetime estimation.
