Damage to the insulation during semi-conductive screen removal - this is probably the number one cause of all cable joint and cable termination failures. Care must be taken when cable jointers are removing the semi-conductive screen, any damage or nick to the cable insulation at this stage will result in creating an unscreened air void.

Since the dielectric strength of air is less than that of the XLPE insulation, the concentration of electrical stress in this area will exceed the dielectric strength of air. The air will ionize causing corona discharge to occur. These discharges bombard the surrounding insulation 100 times a second, and will result in cutting through the insulation and ultimate high voltage power cable failure.
