ABSTRACT:
This invention relates to an assembly of a splice between a cable containing paper insulation and a cable containing oil or petroleum based materials wherein the splice, or at least the end of the cable containing the oil or petroleum based material, is encapsulated in a particulate material such as calcium carbonate and placed under compression in order to prevent the oil or petroleum based material in one cable from migrating into the splice area or into the other cable and damaging the paper insulation in the splice or the other cable. The assembly also prevents the migration of water from either cable into the splice area.
