A fitting for coupling ends of cores of three insulated conductors includes an end termination placed over end portions of the three insulated conductors. The end termination includes three separate openings that pass through the end termination longitudinally. Each of the insulated conductors passes through one of the openings with end portions of the insulated conductors protruding from one side of the end termination. Exposed cores of the end portions of the insulated conductors protrude from the end termination. A cylinder is coupled to the side of the end termination from which the end portions of the insulated conductors protrude. An electrical bus is coupled to the exposed portion of the cores. Electrically insulating material fills the cylinder such that the cores are substantially enclosed in the electrically insulating material. An end cap is coupled to the cylinder to seal off the interior of the cylinder.
1. A method for coupling ends of cores of three insulated conductors, comprising: placing an end termination over end portions of the three insulated conductors, wherein the end termination comprises three separate openings that pass through the end termination, each of the insulated conductors pass
1. A method for coupling ends of cores of three insulated conductors, comprising: placing an end termination over end portions of the three insulated conductors, wherein the end termination comprises three separate openings that pass through the end termination, each of the insulated conductors passing through one of the openings with end portions of the insulated conductors protruding from one side of the end termination with cores of the end portions being at least partially exposed;coupling a fitting sleeve to the side of the end termination from which the end portions of the insulated conductors protrude;filling the fitting sleeve with electrically insulating material with at least a portion of the cores remaining exposed;electrically coupling the exposed portions of the cores;filling the fitting sleeve with electrically insulating material such that the cores are substantially enclosed in the electrically insulating material; andcoupling an end cap to the fitting sleeve. 2. The method of claim 1, wherein the cores of the end portions have been at least partially exposed by removing portions of jackets and electrical insulation from the end portions. 3. The method of claim 1, further comprising coupling jackets of the insulated conductors to the end termination. 4. The method of claim 1, further comprising compacting the electrically insulating material in the fitting sleeve after filling the fitting sleeve with electrically insulating material such that at least the portion of the cores remain exposed. 5. The method of claim 1, further comprising compacting the electrically insulating material in the fitting sleeve after filling the fitting sleeve with electrically insulating material such that the cores are substantially enclosed in the electrically insulating material. 6. The method of claim 1, wherein the fitting sleeve comprises two or more fitting portions coupled together, and wherein at least a first fitting sleeve has a length less than the length of the exposed cores such that at least some portion of the cores extends beyond the first fitting sleeve. 7. The method of claim 1, wherein the fitting sleeve comprises two fitting portions coupled together, the method further comprising coupling a second fitting sleeve to a first fitting sleeve, wherein the second fitting sleeve has a length that extends beyond the length of the exposed cores above the first fitting sleeve. 8. The method of claim 1, further comprising filling the fitting sleeve with electrically insulating material such that the cores are substantially enclosed in the electrically insulating material by: filling the fitting sleeve with some electrically insulating material;compacting the electrically insulating material to a first level;filling the fitting sleeve with additional electrically insulating material; andcompacting the electrically insulating material to a second level that substantially encloses the cores in the electrically insulating material. 9. The method of claim 1, further comprising electrically coupling the exposed portions of the cores with an electrical bus. 10. The method of claim 1, wherein the end cap comprises a guide for guiding installation of the insulated conductors into a wellbore. 11. The method of claim 1, wherein the electrically insulating material comprises magnesium oxide and/or boron nitride. 12. A fitting for coupling ends of cores of three insulated conductors, comprising: an end termination placed over end portions of the three insulated conductors, wherein the end termination comprises three separate openings that pass through the end termination, each of the insulated conductors passing through one of the openings with end portions of the insulated conductors protruding from one side of the end termination, exposed cores of the end portions of the insulated conductors protruding from the end termination;a fitting sleeve coupled to the side of the end termination from which the end portions of the insulated conductors protrude;an electrical coupling between the exposed portions of the cores;electrically insulating material filling the fitting sleeve such that the cores are substantially enclosed in the electrically insulating material; andan end cap coupled to the fitting sleeve. 13. The fitting of claim 12, wherein the fitting sleeve comprises two or more fitting portions coupled together, and wherein at least a first fitting sleeve has a length less than the length of the exposed cores such that at least some portion of the cores extends beyond the first fitting sleeve. 14. The fitting of claim 12, wherein the fitting sleeve comprises two fitting portions coupled together, wherein the second fitting sleeve has a length that extends beyond the length of the exposed cores above the first fitting sleeve. 15. The fitting of claim 12, wherein the electrical coupling between the exposed portions of the cores comprises an electrical bus. 16. The fitting of claim 12, wherein the end cap comprises a guide for guiding installation of the insulated conductors into a wellbore. 17. The fitting of claim 12, wherein the electrically insulating material comprises magnesium oxide and/or boron nitride. 18. A fitting for coupling ends of cores of two or more insulated conductors, comprising: an end termination placed over end portions of the two or more insulated conductors, wherein the end termination comprises separate openings for each insulated conductor that pass through the end termination, each of the insulated conductors passing through one of the openings with end portions of the insulated conductors protruding from one side of the end termination, exposed cores of the end portions of the insulated conductors protruding from the end termination;a fitting sleeve coupled to the side of the end termination from which the end portions of the insulated conductors protrude;an electrical coupling between the exposed portions of the cores;electrically insulating material filling the fitting sleeve such that the cores are substantially enclosed in the electrically insulating material; andan end cap coupled to the fitting sleeve. 19. The fitting of claim 18, wherein the fitting sleeve comprises two or more fitting portions coupled together, and wherein at least a first fitting sleeve has a length less than the length of the exposed cores such that at least some portion of the cores extends beyond the first fitting sleeve. 20. The fitting of claim 18, wherein the end cap comprises a guide for guiding installation of the insulated conductors into a wellbore.
