ABSTRACT:
An electrical cable has features that allow its use in wells containing oil, water and gas, for use with submersible pumps. The cable has a number of conductors. Each conductor is surrounded by an insulating layer of oil and brine resistant thermosetting material. The insulating layer is permeable to gas. A polymeric jacket is extruded around all of the conductors, separating the conductors from each other and in direct physical contact with the insulating layers. Perforations are placed in the jacket at regular intervals. During rapid depressurization, gas absorbed in the insulating layers is able to flow freely from the cable by means of the perforations in the jacket. The jacket has sufficient strength to prevent rupturing of the insulating layers during depressurization.
