Abstract
Abstract A flexible tubing cable assembly having an outer sheath of flexible thin wall metal tubing with one or more conductors therein, each of the conductors having a first layer of a first dielectric and a second layer of a second dielectric, with a third dielectric material filling the space between the one or more conductors and the interior of the tubing. In one of several embodiments, the first dielectric is a polyimide film; the second dielectric is a layer of ethylene propylene compound; and the third dielectric is a magnesium oxide insulation. In another embodiment, the first dielectric is a polyimide; the second dielectric is fiberglass; and the third dielectric is a synthetic rubber. The tubing, in cross-section, may be circular or ovate. In addition, the tubing may be of either high tensile strength or low tensile strength, depending upon the weight supported, for instance, if a submersible pump is supported, high tensile strength tubing is used.
