To reduce the huge loss caused by the failure of long-term transmission wire, proper method for the life time prediction is imminent. In this paper, to accomplish long-term service time prediction of carbon fiber composite core (CFCC) wire, an accelerated degradation test is conducted, where 15 samples are allocated to three temperature levels and the degradation data sets under different condition are obtained. Based on the test results, an accelerated degradation model is constructed where Arrhenius function is incorporated to characterize the relationship of degradation rate and temperature. Finally, the median service life and 95% reliable service life of CFCC wire for several conditions is predicted based on the test results and the accelerated degradation model.
