Summary:A cable joint for high voltage electric power cables (10, 20) and with an improved smooth screen connection is provided. This cable joint is formed by first applying a cold shrinkable insulating joint-body (5) over a semi-conductive plate covering a junction connector and ends of the semi-conductive screens (13, 23) of the cables. A copper mesh (9) is then provided over this insulating joint-body. Ends of the wires of the wired-screens (12, 22) of the cables are bent back over the copper mesh and spread so as to cover the whole circumference thereof. A copper plate (30) is then rolled around the joint, covering the conductive wires of the wired-screens. Finally, a cold shrinkable insulating joint-cover (3) is applied over the joint, covering and exerting a permanent pressure onto the conductive plate (30) over the wires of the wired-screens (12, 22). Because the wires are equally distributed over the perimeter of the copper mesh, the joint has a smooth design with a constant diameter. Additionally, because of the symmetrical cylindrical pressure on underlying insulating mastic, the latter is prevented to flow away in any direction preventing so the risk of partial discharges and product failure.
