Abstract
A submersible pump cable includes a conductive air line that is configured to transport both an electrical current and pressurized air.
Claims13
A submersible pump cable comprising:
- a conductive air line configured to transport both electrical current and pressurized air, the conductive air line including a hollow tube composed of a flexible metal, the hollow tube having a longitudinal axis running lengthwise through a center of the hollow tube, the hollow tube having a radially outer surface relative to the longitudinal axis;
- and
- an insulating material that surrounds the hollow tube throughout a length of the hollow tube, the insulating material disposed in physical contact with an entirety of the radially outer surface of the hollow tube throughout the length of the hollow tube.
The submersible pump cable of the hollow tube composed of braided individual metal strands.
A submersible pump cable comprising:
- a conductive air line structured to transport both electrical and pressurized air;
- an insulating material surrounding a length of the conductive air line, the conductive air line having an outer surface and an inner surface that are continuous along the length of the conductive air line and continuous along a cross section of the conductive air line, the cross section taken in a direction perpendicular to the length, the insulating material disposed in physical contact with an entirely of the outer surface of the conductive air line along the length of the conductive air line.
