Flexible vulcanized joint between two electric power cables and process for producing said joint

A process for producing a flexible vulcanized joint between two electric power cables, each cable having a metal conductor and an electric insulation system radially surrounding the conductor, the electric insulation system having an inner semi-conducting layer, an insulation layer, and an outer semi -conducting layer, the process comprising the following steps:

• i) Producing an exposed conductor joint between each end of the two cable ends to be joined;
• ii) Producing an inner semi-conducting layer that radially surrounds and covers the exposed conductor joint;
• iii) Winding an insulation tape including an organic peroxide around the inner semi-conducting layer thereby radially surrounding and covering the inner semi-conducting layer;
• iv) Curing the insulation tape and thereby producing an insulation layer;
• and
• v) Producing an outer semi-conducting layer that radially surrounds and covers the insulation layer;
• wherein the step iii) of winding the insulation tape around the inner semi -conductor layer is performed under an oxygen-free atmosphere.
