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 and with each conductor having a plurality of wires that are surrounded by an insulating jacket. The wires can be copper or other conductive wires. The insulating jacket surrounding each set of wires or each conductor can be comprised of ethylene tetrafluoroethylene, polytetrafluoroethylene, polytetrafluoroethylene tape, perfluoroalkoxyalkane, fluorinated ethylene propylene or a combination of materials. A first layer of a plurality of strength members is wrapped around the outer insulating jacket. A second layer of a plurality of strength members may be wrapped around the first layer of a plurality of strength members. The first and/or second layer of strength members can be made of single wires, synthetic fiber strands multi-wire strands, or rope. If either or both layers are made up of synthetic fiber, then the synthetic fibers may be surrounding and encapsulated by an additional insulating and protective layer.
1. A high-power low-resistance electromechanical cable comprising:
a conductor core comprising a plurality of conductors substantially encapsulated by a first insulating jacket, wherein each conductor comprises one or more conducting wires surrounded by a conductor jacket, wherein at least one of said conductors comprises a compacted conductor with at least one of said one or more conducting wires having a defaulted cross-section, wherein one or more conductors of said plurality of conductors comprises one or more twisted paired conductor strands, wherein said twisted paired conductor strand comprises two silver-plated copper conductors insulated with polytetrafluoroethylene or polytetrafluoroethylene tape and twisted together after insulation, a braided silver-plated wire shield substantially encasing said twisted paired insulated conductors, and a jacket substantially encasing said shield, wherein said jacket is made of ethylene tetrafluoroethylene fluropolymer;
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.
2. The cable of claim 1 wherein one or more of conductors of said plurality of conductors wires is replaced with one or more optical fibers.
3. The cable of claim 1 wherein said strength members are made from steel and comprise one of a single wire, a multi-wire strand, or a rope.
4. The cable of claim 1 wherein said strength members are high-strength synthetic fibers.
5. The cable of claim 1 wherein a second insulating jacket encapsulates said first insulating jacket and said first armoring layer is wrapped around said second insulating jacket.
6. The cable of claim 5 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.
