Patent

CA 2255482

A multiconductor electrical cable for use in a subterranean wellbore has improved resistance to swelling caused by the absorption of deleterious fluids. The cable comprises a plurality of electrical conductors; at least one layer of an insulation material surrounding the plurality of electrical conductors; a jacket of elastomeric material surrounding the insulated electrical conductors; a fluid barrier surrounding the jacket; and an outer armor surrounding the fluid barrier. The fluid barrier prevents hydrocarbons and water from being absorbed into the jacket of elastomeric material, thereby preventing the swelling of the cable. The outer armor can include a coating of thermoset and/or thermoplastic material to prevent corrosion of the cable's armor, so as to better contain any swelling of the cable.
