A multiconductor electrical cable, for use in a subterranean wellbore, having which a plurality of electrical conductors, a jacket of insulation material, and a non-metallic armor. The non-metallic armor comprises one or more layers of extruded materials or an external wrapping of materials, selected from the group consisting of extruded thermoplastic materials, extruded thermoset materials, and fiber reinforced composite materials. The non-metallic armor eliminates corrosion problems associated with prior metallic armors, and provides significant weight savings over prior metallic armors.

Non-metallic armor for electrical cable

A method of suspending an electric submergible pumping system within a wellbore includes inserting an electric cable within a conduit, such as coiled tubing. One end of the conduit is sealed with one end of the electric cable extending out therefrom. The conduit is filled with a fluid of sufficient volume and sufficient density to float the electric cable within the conduit when the conduit is disposed within a wellbore. An electric submergible pumping system is connected to the conduit, and the electric cable is connected to an electric motor of the electric submergible pumping system. Thereafter, the electric submergible pumping system and the conduit are inserted into the wellbore. Since the cable is floating, i.e., self supporting, within the conduit there is no need for cable anchors or other devices to transfer the weight of the cable to the conduit.
