Corrosion-resistant submersible pump electric cable

摘要

An improved cable and cable sheathing arrangement that affords protection for the conductive elements against corrosion, chemical and physical hazards. In exemplary embodiments described herein, the cable includes a plurality of copper conductors that are individually encased in a thermoplastic insulation. An extruded lead sheath surrounds the thermoplastic insulation. Finally, a thermoplastic jacket encloses the lead sheaths of the conductors in surrounding contact to provide a unitary cable. A cost effective cable is provided, and the need for an external metal armor is reduced or eliminated. Additionally, the cable provides substantial and adequate resistance to corrosion and physical hazards.
