ABSTRACT:
An electrical cable for a submersible well pump is provided which is resistant to attack by hydrogen sulfide and which is less susceptible to damage from expanding gases during decompression. The electrical cable has a central copper conductor core. The conductor core is surrounded by a layer of electrical insulation material of either thermosetting or thermoplastic material. Surrounding the insulation material is a polymeric, low permeable layer having a hydrogen sulfide permeability rate which is substantially lower than the insulation material. A metal tape layer, such as lead tape, surrounds the low permeable layer. One or more conductor cores together with the insulation, low permeable layer and metal tape layer can be embedded in an elastomeric jacket and provided with an outer metal armor to provide a single electrical cable.
