In this paper, the withstand voltage characteristics of cross-linked polyethylene (XLPE) and its nanocomposites at different temperatures was systematically measured by step voltage rising method. A new method for calculating the key parameters of the Crine model was proposed, and the activation energy and charge acceleration distance of XLPE and its nanocomposites at different temperatures were calculated on the basis of the experimental results of step voltage rising method. The results show that the characteristic breakdown time of both the materials decreases with the increase of temperature. At the same temperature and time step, the characteristic breakdown voltage and breakdown time of XLPE nanocomposites are higher than that of XLPE, and the electrical ageing life of XLPE nanocomposites is longer than that of XLPE under high voltage. With the increase of temperature, the ageing activation energy and charge acceleration distance of the two materials increase. Under the same temperature, both the ageing activation energy and charge acceleration distance of XLPE nanocomposite are smaller than that of XLPE. It is more intuitive to reflect the ageing resistance of insulating materials by activation energy and charge acceleration distance on basis of Crine model than the ageing life index on basis of the inverse power model or exponential model.
