1. A joint for joining a first electric cable and a second electric cable, each cable having an electric conductor and an insulation system surrounding the electr conductor, the insulation system having an inner semiconducting layer, an insulating layer and an outer semiconducting layer, wherein the end sections of the two electrical conductors form an electrical conductor joint;
the joint comprising:
an inner layer made of a crosslinked first polymeric semiconducting material, for surrounding the electric conductor joint,
an intermediate insulating layer made of a thermoplastic polymeric insulating material, covering an external surface of the inner semiconducting layer, and
an outer layer made of a second polymeric semiconducting material, covering an external surface of the insulating layer,
wherein the second polymeric semiconducting material is a thermoplastic semiconducting material.
