Abstract
An improved corrosion-resistant magnetic influence minesweeping cable is provided. The cable produces a magnetic field that simulates a ship's magnetic signature as the ship passes through the sea. It has an outer anode conductor made of titanium-clad copper with mixed metal oxide at its aft end, an outer cathode conductor made of nickel-clad copper at its forward end, an inner conductor made of aluminum that runs the length of the cable, and a steel core strength member that also runs the length of the cable. The outer anode conductor is in electrical contact with the inner conductor. The outer cathode conductor is insulated from the inner conductor. The outer cathode conductor and the inner conductor can be connected to an electrical power source onboard a towing vessel.
Claims13
A magnetic influence cable for minesweeping operations, said cable comprising:
- a coaxial inner conductor cable having an aft portion and a forward portion, said inner conductor cable comprised of a core strength member with a perimeter separator, an inner conductor having a plurality of twisted threads of aluminum, a first binder, and a covering insulator having an outer perimeter, said covering insulator being adhered to the inner conductor by said first binder, wherein said inner conductor cable extends substantially through the entire length of the magnetic influence cable;
- an aft electrode comprised of an outer anode conductor having an exposed conductive layer of a plurality of twisted conductive wires, said conductive layer embedded in said covering insulator at said aft portion of said inner conductor cable, wherein said aft electrode is in electrical connection with said inner conductor;
- a forward electrode having a forward portion, said forward electrode comprising an outer cathode conductor having an exposed conductive layer of a plurality of twisted conductive bundles of strands embedded in said covering insulator at said forward portion of said inner conductor cable, wherein said forward electrode is electrically insulated from said inner conductor, and said outer cathode conductor extends to a forward end of the magnetic influence cable;
- and
- an insulating jacket covering said forward portion of said forward electrode and adhered thereto by a second binder, wherein said jacket extends to the forward end of the magnetic influence cable.
