An insulating cable connection

The invention consists of an insulating cable connection for joining an insulated electric power cable with a cable means, said electric cable comprising a wire conductor with a polymer based insulation system around said wire conductor, wherein the cable connection comprises a connection insulation system covering a wire conductor joint portion, wherein the connection insulation system is produced in the same polymer material selection as the insulation system of the first electric cable. By an insulating cable connection according to the invention, a more homogeneous electrical field in the longitudinal direction of the cable is obtained. Thus, a cable connection according to the invention results in an electrically stronger cable connection and a more robust insulating cable connection for high-voltage cables.
