A multiconductor electrical cable for use in a subterranean wellbore comprises 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 extrude d thermoplastic materials, extruded thermoset materials, and fiber reinforced comp osite materials. The non-metallic armor eliminates corrosion problems associated with prior metallic armors, and provides significant weight savings over prior metallic arm ors.
