1. A downhole electrical transmission system comprising:

  • first and second tubular bodies coupled together by mating threads, each tubular body comprising a bore;

    an electrical conductor assembly disposed within the bore of each tubular body; and

    at least one end of each assembly comprising an electrical contact surrounded by a dielectric material, the electrical contact and dielectric material forming a polished, planar mating surface;

    the planar mating surface being spring-loaded by a resilient material;

    wherein the mating surfaces span an entire cross section of the end and are perpendicular to a central axis of the tubular bodies; and

    wherein the mating surfaces of each electrical conductor assembly are substantially abutted under a compressive load when the tubular bodies are fully mated.
