An insulating system for splicing a pair of cables having at least partially exposed non-insulating portions joined with a metallic connector is disclosed. The insulating system includes an insulating tube constructed from a shape memory material having a central section having a substantially elliptical cross-section and a pair of end sections with substantially circular cross-sections. A pair of support cores is removably insertable in each of the end sections for holding the end sections in a stretched configuration. When the insulating system is placed about the cables and the connector and the support cores are removed from the end sections, the end sections return to a pre-stretched configuration, thereby completing a splice of the cables.

1. An insulating system for splicing a pair of cables comprising: an insulating tube constructed from a shape memory material with a non-expanded central section having a substantially elliptical cross-section and with a pair of end sections each having substantially circular cross-sections; anda pair of support cores removably insertable in the end sections for holding the end sections in a stretched configuration,wherein, when the insulating system is placed about the cables and the support cores are removed from the end sections, the end sections return to a pre-stretched configuration, thereby completing a splice of the cables. 2. The insulating system of claim 1, wherein the support cores are configured to have a combined length that is substantially shorter than the insulating tube. 3. The insulating system of claim 1, wherein an inside circumference of the elliptically shaped non-expanded central section of the insulating tube is substantially the same as or larger than an outside circumference of the support cores. 4. The insulating system of claim 1, wherein the support cores are substantially circular in cross-section. 5. The insulating system of claim 1, wherein the shape memory material comprises a form of rubber. 6. The insulating system of claim 5, wherein the shape memory material is at least one of Ethylene-propylene-diene-monomer (EPDM) and silicone. 7. The insulating system of claim 1, wherein the support cores have a substantially smooth shape configured to be friction fit into the end sections. 8. The insulating system of claim 7, further comprising a film layered between a corresponding one of the support cores and a corresponding one of the end sections. 9. The insulating system of claim 8, wherein the film is configured to be folded back on itself to form an inner film layer adjacent to the corresponding one of the support cores and to form an outer film layer adjacent to the corresponding one of the end sections. 10. The insulating system of claim 9, wherein the inner film layer is adhered to the corresponding one of the support cores with an adhesive. 11. The insulating system of claim 8, wherein the film comprises mylar. 12. The insulating system of claim 8, wherein the film is a single layer located between a support core and an end section on each end of the splice, the single layer film folded into an inner diameter of the support core and secured therein. 13. The insulating system of claim 1, wherein the support cores have a substantially spiral shape configured to be fully wound and inserted into the end sections. 14. The insulating system of claim 1, wherein the end sections each comprise a hollow lip extending about a portion of an inner circumference of the end sections. 15. The insulating system of claim 14, further comprising a sealant material configured to be received between each of the support cores and the insulating tube. 16. A method for splicing cables, comprising the steps of: providing an insulating system comprising an insulating tube constructed from a shape memory material with a non-expanded central section having a substantially elliptical cross-section, and with a pair of end sections each having substantially circular cross-sections, and a pair of support cores removably insertable in each of the end sections for holding the end sections in a stretched configuration;placing the insulating system about the cables; andremoving the support cores from the end sections,wherein the end sections return to a pre-stretched configuration, thereby completing a splice of the cables. 17. The method of claim 16, wherein, when the support cores are removed from the end sections, a sealant material is trapped between each of the insulated portions of the cables and the end sections, thereby providing an environmental seal for the spliced cables. 18. The method of claim 16, wherein the support cores have a substantially smooth shape and a film layered between a corresponding one of the support cores and a corresponding one of the end sections,wherein the film is configured to be folded back on itself, andwherein when a support core is removed, a portion of the film in contact with the support core slips out. 19. The method of claim 18, wherein the sealant material remains in place as the film slips out. 20. The method of claim 18, wherein the support cores have a substantially spiral shape configured to be unwound when removed from the end sections. 21. An insulating system for splicing a pair of cables, comprising: an insulating tube constructed from a shape memory material with a central section and with a substantially elliptical cross-section and a pair of end sections with substantially circular cross-sections;a pair of support cores removably insertable in the end sections for holding the end sections in a stretched configuration; anda film inserted between a corresponding one of the support cores and a corresponding one of the end sections, wherein the film is to be folded back on itself to form an inner film layer adjacent to the corresponding one of the support cores and to form an outer film layer adjacent to the corresponding one of the end sections,wherein, when the insulating system is placed about the cables and the support cores are removed from the end sections, the end sections return to a pre-stretched configuration, thereby completing a splice of the cables. 22. The insulating system of claim 21, wherein the inner film layer is adhered to the corresponding one of the support cores with an adhesive. 23. The insulating system of claim 21, wherein the film comprises mylar. 24. The insulating system of claim 21, wherein the support cores have a substantially spiral shape configured to be fully wound and inserted into the end sections. 25. The insulating system of claim 21, wherein the end sections each comprise a hollow lip extending about a portion of an inner circumference of the end sections. 26. The insulating system of claim 25, further comprising a sealant material configured to be received between each of the support cores and the insulating tube. 27. The insulating system of claim 21, wherein the support cores are configured to have a combined length that is substantially shorter than the insulating tube. 28. The insulating system of claim 21, wherein an inside circumference of the elliptically shaped central section of the insulating tube is substantially the same as or larger than an outside circumference of the support cores. 29. The insulating system of claim 21, wherein the support cores are substantially circular in cross section. 30. The insulating system of claim 21, wherein the shape memory material comprises a form of rubber. 31. The insulating system of claim 30, wherein the shape memory material is at least one of Ethylene-propylene-diene-monomer (EPDM) and silicone. 32. A method for splicing cables, comprising the steps of: providing an insulating system comprising an insulating tube constructed from a shape memory material with a central section and with a substantially elliptical cross-section, a pair of end sections with substantially circular cross-sections, and a pair of support cores removably insertable in each of the end sections for holding the end sections in a stretched configuration;placing the insulating system about the cables; andremoving the support cores from the end sections,wherein the support cores have a film layered between a corresponding one of the support cores and a corresponding one of the end sections,wherein the film is configured to be folded back on itself,wherein when a support core is removed, a portion of the film in contact with the support core slips out, andwherein the end sections return to a pre-stretched configuration, thereby completing a splice of the cables.
