Abstract	The characteristics of charge accumulation in XLPE (cross-linked polyethylene) with heat-treated semiconductive electrodes are investigated. Both fresh ones and vacuum degassed electrodes are used. Vacuum treatment reduces the amount of residual by-products of the crosslinking reaction, which helps the buildup of homocharges near the electrodes. This indicates that the heterocharge peak observed in XLPE is caused by such by-products. In addition, the negative charges are observed near both electrodes when the charge profiles are collected during the voltage application, whereas the heterocharges are observed when the charge profiles are collected after the removal of voltage. The observation of negative charges near both electrodes is attributed to the strong contribution of injected electrons near the cathode.<>
