With the increasing application of cable in various fields, more and more attention has been paid to the aging of cable. In order to ensure the operation safety of instruments and all kinds of equipment, it is urgent to find a fast and accurate method to evaluate the residual life of cable. In this paper, a second-order kinetic model is adopted and the Arrhenius thermal aging equation is improved. In view of the working environment with relatively high temperature, the thermal aging life prediction model for cable is obtained to calculate the residual life rapidly. It provides theoretical support for timely detection of risks and elimination of potential accidents.
