Abstract

A cable having universal applications for transmitting any kind of electrical signal, including AC and DC power, for sensitive test instruments cables and, particularly, for conducting audio, video and digital signals through a stranded metal wire conductor can consist of virtually any configuration, or randomly-no configuration. The cable can be shielded or unshielded to suit personal preferences or specific applications. The cable is made from wire that can be braided in any Litz wire configuration that provides a desired number of twists per foot. The cable can be used to transmit any type of electrical signal with the results dependent on which gauge of wire listed below is used. The following list includes twenty one gauges of wire which are significant because they represent the lowest to highest performance capabilities in my cable and are numbered low to high for this purpose, starting with gauge 40, and finishing with gauge 60. These gauges of wire represent a progressively better and more accurate electrical signal transducer with each higher numbered gauge: 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60. In the preferred embodiment, the main determining factor in performance is the specific gauge of wire in use. Thus, a 40 gauge wire is lower in performance, with a 60 gauge wire having the theoretical highest performance. The cable can be made with air as a dielectric or any other type of jacketing can be used.

Claims

1. An acoustically transparent stranded cable, consisting of:

a plurality of metal wire strands;

wherein each strand comprises a wire size selected from AWG numbered gauge wire sizes 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, and 60;

wherein all strands comprise the same wire size; and

wherein 250-1050 strands are used for an interconnect cable and 640-3100 strands are used for a speaker cable.

2. The cable of claim 1 further comprising:

each strand being individually insulated with a solderable enamel coating to prevent surface oxidation.

3. The cable of claim 1, further comprising:

a cable shield.

4. The cable of claim 1, wherein said strands are braided in a predetermined Litz wire configuration to provide a selected number of twists per unit of cable length.

5. The cable of claim 1, further comprising:

a dielectric jacketing.

6. The cable of claim 1, wherein said strands are braided in a random fashion.
