High-power low-resistance electromechanical cable
A high-power low-resistance electromechanical cable constructed of a conductor core comprising a plurality of conductors surrounded by an outer insulating jacket. Each conductor has a center conductor element surrounded by a plurality of copper wires, wherein the plurality of copper wires is compacted to have a non-circular cross-section. The center conducting element may be one of a fiber optic strand, a copper wire having an indented outer surface, or a twisted conductor pair. Each conductor also includes a conductor insulating jacket encapsulating the plurality of copper wires and center conducting element. A first armoring layer of a plurality of strength members is wrapped around the outer insulating jacket. A second armoring layer of a plurality of strength members may also be wrapped around the first layer. A polymer jacket layer may encapsulate the first and/or second armoring layers of strength members.
1. A high-power low-resistance electromechanical cable comprising:
a conductor core comprising a plurality of conductors substantially encapsulated by a first insulating jacket, and wherein each conductor of said plurality of conductors comprises six copper wires wrapped around a center conducting element and a conductor insulated jacket encapsulating said six copper wires and said center conducting element, wherein said six copper wires are compacted around said center conductor element prior to being encapsulated by said conductor insulated jacket resulting in said six copper wires having a non-circular cross-section, wherein said center conductor element comprises a copper conductor wire having an indented outer surface due to the compaction of said six copper wires; and
a first armoring layer comprised of a first plurality of strength members helically wrapped around said first insulating jacket, and
a second armoring layer comprised of a second plurality of strength members helically wrapped around said first armoring layer of strength members.
2. The cable of claim 1 wherein said center conductor element comprises at least one fiber optic strand.
3. The cable of claim 1 wherein said center conductor element comprises one or more twisted paired conductor strands.
4. The cable of claim 1 wherein said first plurality and said second plurality of strength members are steel.
5. The cable of claim 4 wherein said first plurality of steel strength members is one of a single wire, a multi-wire strand, or a rope, and said second plurality of steel strength members is one of a single wire, a multi-wire strand, or a rope.
6. The cable of claim 1 wherein said first plurality of strength members comprises high-strength synthetic fibers and said second plurality of strength members comprises high-strength synthetic fibers.
7. The cable of claim 6 wherein said second armoring layer of strength members is surrounded and substantially encapsulated by a polymer layer.
8. The cable of claim 1 wherein said second armoring layer of strength members is surrounded and substantially encapsulated by a polymer layer.
9. The cable of claim 1 wherein a second insulating jacket encapsulates said first insulating jacket and is disposed between said first armoring layer and said first insulating jacket.
10. The cable of claim 9 wherein each of said first insulating jacket and said second insulating jacket is one of ethylene tetrafluoroethylene, polytetrafluoroethylene, polytetrafluoroethylene tape, perfluoroalkoxyalkane, fluorinated ethylene propylene or a combination thereof.
11. The cable of claim 10 wherein the first insulating jacket is a different material than said second insulating jacket.
