1. An electrical cable comprising:
- at least two conductor wires, said wires being parallel and spaced from one another;
an inner jacket encasing said conductor wires and forming a webbing therebetween;
a flat, unitary ribbon composed of a plurality of interconnected high-strength textile fibers disposed against one side of the webbing, said ribbon having a width approximately equal to the width of said webbing, said ribbon extending longitudinally of the cable; and
an outer sheath extending longitudinally of said cable and surrounding said conductors, said inner jacket, and said ribbon.

Abstract
A high-strength textile ribbon disposed against the webbing of the core of a parallel lead cable significantly enhances the breaking strength of the incorporating cable without significantly affecting its flexibility or electrical properties. Breaking strength may be further enhanced by bonding the ribbon to the webbing and the adjacent portion of the cable sheath.

6. An electrical cable particularly adapted for the transmission of high frequency electrical energy, the cable comprising:
- two parallel spaced conductors, an inner jacket of polyethylene encasing the conductors and forming a webbing therebetween, the thickness of said webbing being less than the diameter of the jacket about said conductors, leaving a channel shaped recess between the conductors, an extruded outer jacket of foamed polyethylene surrounding said conductors and said inner jacket, and an elongated ribbon of textile fibers of high tensile strength extending longitudinally along the cable, one side of said ribbon being disposed against a portion of the outer sheath, the other side of the ribbon being disposed against the webbing, the width of said ribbon being approximately equal to the width of the webbing and the ribbon being disposed in said channel shaped recess, whereby the strength of the cable is increased by at least a factor of two without substantially affecting the electrical performance of the cable.
