Abstract: In various embodiments, a well casing seal that comprises an inner sleeve containing cured material bonded to exposed electrical conductor; an outer sleeve established substantially around said inner sleeve; at least one sealer established between an outer surface of the inner sleeve and an inner surface of the outer sleeve, wherein the outer sleeve has a threaded outer surface configured to engage threads of the inner surface of a threaded power conductor hole of a wellhead mandrel. Related methods, relative to installation and manufacture are also disclosed.

Abstract: Aspects of the inventive technology may relate to a physical enclosure designed to house electrical componentry inside. More specifically, the inventive technology may relate to a physical enclosure that is designed to allow for the enclosure, perhaps within the same, unitary structure, of conductors (wires) as they enter the ground and wire splice devices that connect those wires with wires of smaller diameter. Aspects of the inventive technology may relate to provision of a wire splice mount(s) that hold splices in fixed position relative to the physical enclosure.
