Abstract
A twin-axial cable comprises a central core around which two conductors are helically wrapped. Interspersing a plurality of spacers between the conductors determines the relative placement of the two conductors on the core. A dielectric barrier encases the core, conductors, and spacers.
Claims12
A cable, comprising
- (a) an interior element having
- (i) a longitudinal cylindrical central core;
- (ii) two insulated conductors helically wrapped around the core so that the conductors are substantially diametrically opposed from each other along the length of the core;
- (iii) a plurality of cylindrical spacers helically wrapped around the core between the conductors to ensure that the conductors are remain substantially diametrically opposed from each other along the length of the core;
- (b) a dielectric material encasing the interior element;
- (c) a shield surrounding the dielectric material;
- and
- (d) an outer dielectric sheath surrounding the shield.

A method of forming a cable, comprising the steps of:
- (a) helically wrapping two insulated conductors and a plurality of spacers around a longitudinal, cylindrical central core so that the spacers are located between the conductors in a manner that ensures the conductors are substantially diametrically opposed from each other along the length of the core;
- (b) encasing the conductors, the plurality of spacers, and the central core within a dielectric material;
- (c) surrounding the dielectric material with a shield;
- and
- (d) encasing the shield within an outer dielectric sheath.

A method of forming a twin-axial cable, comprising the steps of:
- (a) helically wrapping two insulated conductors and a plurality of spacers around a longitudinal, cylindrical central core so that the spacers are located between the conductors in a way that ensures the conductors are substantially diametrically opposed from each other along the length of the core;
- (b) injecting a self-healing fluidic substance in the interstices between the spacers, the insulated conductors, and the core;
- (c) encasing the conductors, the plurality of spacers, and the central core within a dielectric material.
- (d) surrounding the dielectric material with a shield;
- and
- (e) encasing the shield within an outer dielectric sheath.
