Medium-voltage crosslinking polyethylene insulation stress cone cable terminal and repair method

The invention relates to a medium-voltage crosslinking polyethylene insulation stress cone cable terminal. The medium-voltage crosslinking polyethylene insulation stress cone cable terminal comprises a branch sleeve, a sealing pipe, a conductive wire core, an inner shielding layer, an insulating layer, a semi-conductive layer, a copper belt shielding layer and a rubber semi-conductive layer and is characterized in that: a polyvinyl chloride (PVC) plastic belt is wrapped between the front side of the cutting mouth of the semi-conductive layer and the rear side of the stop end of the semi-conductive layer; the PVC plastic belt forms an insulation stress cone; the insulation stress cone at the position corresponding to the cutting port of the semi-conductive layer has the maximum appearance size; a rubber semi-conductive belt is wrapped from the maximum appearance size position of the insulation stress cone to the root of a cable; the insulation stress cone and the rubber semi-conductive belt form an insulation
