Claims
- 1. An electrical well cable comprising: a plurality of electrical conductors;
a thermoplastic layer surrounding each of the conductors; a lead sheath surrounding each thermoplastic layer; and a single thermoplastic jacket surrounding and in contact with all of the lead sheaths.
- 2. The cable of claim 1 wherein each of the lead sheaths is extruded around the thermoplastic layer.
- 3. The cable of claim 1 wherein the jacket has an exterior that defines an exterior surface of the cable.
- 4. The cable of claim 3 wherein the conductors are cabled together to provide a substantially round profile for the cable.
- 5. The cable of claim 3 wherein the conductors are substantially aligned to provide a substantially flat profile for the cable.
- 6. The cable of claim 1 wherein the thermoplastic layer is substantially comprised of polypropylene.
- 7. The cable of claim 1 wherein the thermoplastic layer is substantially comprised of EPDM.
- 8. The cable of claim 1 wherein the thermoplastic layer has a thickness of approximately 75 mils.
- 9. The cable of claim 1 wherein each lead sheath has a thickness of approximately 40 mils.
- 10. A cable for interconnecting a submersible well pump to a power source, the cable comprising:
three electrical conductors; a separate polypropylene insulation layer surrounding each of the conductors; a separate lead sheath surrounding each of the insulation layers; and a thermoplastic jacket surrounding and in contact with the sheaths, the jacket having an exterior that defines the exterior of the cable.
- 11. The cable of claim 10 wherein the conductors are cabled together to provide a substantially round profile for the cable.
- 12. The cable of claim 10 wherein the conductors are substantially aligned to provide a substantially flat profile for the cable.
- 13. A well pump system comprising: a fluid pump;
a power source for the fluid pump; and an electrically conductive cable operably interconnecting the fluid pump and the power source, the cable comprising:
a) three electrical conductors; b) a separate polypropylene insulation layer surrounding each of the conductors; c) a separate lead sheath surrounding each of the insulation layers; and d) a polypropylene jacket surrounding and in contact with the sheaths, the jacket having an exterior that defines the exterior of the cable.
