A spliced cable including: a first shielded wire, wherein the first shielded wire comprises at least one conductor and a first shield layer having an outer surface coated with a first outer sheath; a second shielded wire, wherein the second shielded wire comprises at least one conductor and a second shield layer having an outer surface coated with a second outer sheath; a third shielded wire, wherein the third shielded wire comprises at least one conductor and a third shield layer having an outer surface coated with a third outer sheath; wherein the first conductor is electrically connected to the second conductor and to the third conductor; and a flexible shield tube, wherein the flexible shield tube comprises a first portion and a second portion longitudinally adjacent or spaced from the first portion.

An insulation system for jointing of high voltage conductors has an inner layer made of a crosslinked first polymeric semiconducting material, an intermediate insulating layer made of a thermoplastic polymeric insulating material, and an outer layer made of a second polymeric semiconducting material. The insulation system is adapted for surrounding the electric conductor joint.
