ABSTRACT:
A conduit is provided for transmitting both electrical power and pressured hydraulic fluid from the surface to a point in a subterranean well. The conduit comprises an outer housing formed of steel or other high tensile strength material and one or more insulated wires of copper or similar low tensile strength, highly conductive metal which are run through the outer housing. Supports are provided between the external surfaces of the insulated wires and the internal wall of the housing to frictionally anchor the insulated wires to the housing. The supports also define fluid passages therethrough so that pressured fluid may be transmitted through the bore of the housing. So that the wires are gravitationally stabilized within the outer housing, the average density of the supports and the pressured fluid is approximately equal to the average density of the insulated wires.
