Abstract
A cable in which a dielectric core is surrounded by a plurality of bundles of wire strands with the wire strands forming each bundle being twisted in a first direction and the bundles being twisted around the solid conductor in a direction opposite the first direction. Insulation means extend around the bundles of wire strands. A pair of cables configured in the above manner are provided to carry the positive and negative signals between a power source and a load.
Claims1
A signal cable assembly comprising:
- a first cable adapted to carry the positive signal between a power source and a load, said first cable comprising:
- an elongated, uninsulated, rod-like solid dielectric material;
- a plurality of bundles of wire strands of conductive material twisted around said dielectric material for collectively carrying said positive signal, the wire strands forming each bundle being twisted in a first direction and the bundles being twisted around said dielectric material in a direction opposite said first direction;
- and
- insulation means extending around said bundles of wire strands;
- and
- a second cable adapted to carry the negative signal between said power source and said load, said second cable comprising:
- an elongated, uninsulated, rod-like solid dielectric material;
- a plurality of bundles of wire strands of conductive material twisted around said dielectric material for collectively carrying said negative signal, the wire strands forming each bundle being twisted in a first direction and the bundles being twisted around said dielectric material in a direction opposite said first direction;
- and
- insulation means extending around said bundles of wire strands;
- said first and second cables being disposed in a juxtaposed parallel relationship with their respective insulation means molded together.
