In order to study the effect of stress cone on the accumulation of space charge, we designed a cable model with stress cone structure. A platform was built to perform the combined electric and thermal ageing on the model cable. The distribution of space charge before and after ageing was measured by pulse electro-acoustic method, and the accumulation of space charge at different axial and radial positions was compared. The results show that more space charge accumulates at the root of the stress cone, and the accumulated space charge mainly distributes on the outside of the insulation layer of the cable. To make a preliminary explanation of this phenomenon, it is believed that the electric field distortion caused by the stress cone makes the space charge easy to accumulate in this area.
