A thermal shield and hermetic seal is provided to prevent deterioration of plastic insulation in a cable including a plurality of insulated conductors. The shield includes a sheet of aluminum material wrapped around exposed insulated conductors of the cable, a pressure wrap superposed over the sheet of aluminum material, the pressure wrap being wrapped over the sheet of material, and an enclosure housing the wrapped insulated conductors. The shield and seal thus provides thermal and hermetic protection that prevents heat exposure as well as infiltration of oxygen and ultraviolet radiation into the splice for preventing deterioration of plastic insulation in the conductors of the cable in the area of the splice. A method is also provided for protecting conductor access points and permitting re-access thereto. The method includes opening a conducting access point cover, removing the conductor access point cover if necessary, and exposing insulated conductors to allow access thereto. The method further includes performing any necessary splicing, servicing and maintenance, wrapping the insulated conductors with a first wrap, wrapping the first wrap with a pressure wrap after completion of the servicing, and closing the conductor access point cover. The first wrap includes an aluminum wrapping material, and the pressure wrap is wrapped over the first wrap using a half lap double wrap method. Additionally, the method may include sealing an end of the pressure wrap to secure the end of the pressure wrap in position, wherein the sealing is performed by wrapping a piece of self-adhesive tape around the pressure wrap, and twisting an outer end of said sealing tape to form a pigtail to permit ease of re-entry.
