Patent ID: 7193150

Claim:
A submersible pump cable comprising: a hollow air line, the hollow air line surrounding and defining a void that extends along a length of the hollow air line, the hollow air line having a radially outer surface; a first conductive element having a length end a radially outer surface; a first insulating sheath radially surrounding the first conductive element and contiguous with the radially outer surface of the first conductive element along the length of the first conductive element, the first insulating sheath having a length and a radially outer surface, and a jacket surrounding the hollow air line and the first insulating sheath, the radially outer surface of the hollow air line having a cross-section in a direction perpendicular to the length of the hollow air line that forms a closed loop, the radially outer surface of the first insulating sheath having a cross-section in a direction perpendicular to the length of the first conductive element that forms a closed loop, the jacket contiguous with the radially outer surface of the hollow air line along the cross-section of the hollow air line, and the jacket contiguous with the radially outer surface of the first insulating sheath along the cross-section of the first insulating sheath.
