Abstract
A method for preparing an electrical cable may include coupling an injection barrel to an electrical cable that includes one or more conductors surrounded by a porous insulating material. The method may also include injecting epoxy resin into a chamber of the injection barrel, and the chamber may be fluidly coupled to an end face of the porous insulating material. Additionally, the method may include 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.
Claims15
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.
A method for connecting a prepared electrical cable, comprising:
- inserting the prepared electrical cable into a cable connection, wherein the cable connection comprises a first geometry and the prepared electrical cable comprises a shaped epoxy-solidified portion of a porous insulating material comprising a second geometry complementary to the first geometry, wherein the prepared electrical cable is prepared by:
- coupling an injection barrel to an unprepared electrical cable, wherein the unprepared electrical cable comprises one or more conductors surrounded by the 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;
- removing the injection barrel to expose the epoxy-injected portion of the porous insulating material;
- and
- cutting into the epoxy-injected portion of the porous insulating material to generate the second geometry.
