## Abstract To study the space charge generation in crossβlinked polyethylene (XLPE) and ethylene propylene copolymer (EPR), space charge profiles in both materials are measured using the PEA method. The experimental results demonstrated a large difference in the detected charge profiles between XL
High-density polyethylene (HDPE) and low-density polyethylene (LDPE) were irradiated in vacuo at 30 -220 and 30 -360Β°C, respectively, with β₯-rays at doses of 10 -400 kGy. Temperature dependence of cross-linking and gas evolution was investigated. It was found that cross-linking was the predominant p
