1. A method for preparing an electrical cable, comprising:
coupling an injection barrel to the electrical cable, wherein the electrical cable comprises one or more conductors surrounded by a porous insulating material within an outer casing;
injecting, via one or more ports, epoxy resin into a chamber of the injection barrel, wherein the chamber surrounds the one or more conductors and is fluidly coupled to an end face of the porous insulating material;
pressurizing the chamber such that the epoxy resin is forced to penetrate into the end face of the porous insulating material; and
removing the injection barrel to expose an epoxy-injected portion of the porous insulating material.
