Abstract
A method for manufacturing an electric cable joint is described. The method includes: a step of providing two electric cables, each cable containing an electric conductor and a thermoplastic insulation system surrounding the electric conductor and containing an inner and an outer thermoplastic semiconducting layers and a thermoplastic insulating layer; a step of joining the terminal portions of the electric conductors of the first and second electric cables to form an electric conductor joint; a step of surrounding the electric conductor joint with a joint inner layer of a thermoplastic semiconducting material having a dynamic storage modulus E'; a step of surrounding the joint inner layer with a joint insulating layer of a thermoplastic insulating material having a dynamic storage modulus E′smaller than E′; and a step of surrounding the joint insulating layer with a joint outer layer of a thermoplastic semiconducting material having a dynamic storage modulus E′.
