## Abstract

An electrical assembly for transmitting signals having a wire or cable conductor core, an electrically-insulating jacket surrounding and enveloping the core, and a surrounding braided shield formed from yarns of nickel-plate carbon fibers. Typically each fiber has a diameter of 5-10 microns and the yarn contains 800 to 12,000 fibers.

## Claims

### Claim 1

A shielded electrical conductor unit for transmitting electrical signals, comprising a composite having an electrically-conductive cable core, an electrically-insulating elastomeric jacket surrounding and enveloping said core, and a braided shield surrounding and enveloping said insulating jacket, said braided shield being formed from spun yarns of nickel-plated carbon fibers.

### Claim 2 (depends on 1)

A shielded electrical conductor unit for transmitting electrical signals as defined in claim 1, wherein each individual fiber in said braided shield has a diameter of from 5 to 10 microns.

### Claim 3 (depends on 1)

A shielded electrical conductor unit for transmitting electrical signals as defined in claim 1, wherein each yarn in said braided shield has from 800 to 12,000 fibers.

### Claim 4

A method of transmitting an electrical signal with concurrent suppression of interference which comprises transmitting said current through a conductor unit comprising a composite having an electrically-conductive cable core, an electrically-insulating elastomeric jacket surrounding and enveloping said core, and a braided shield surrounding and enveloping said insulating jacket, said braided shield being formed from spun yarns of nickel-plated carbon fibers.

### Claim 5

A conductor for transmitting electrical signals, said conductor being shielded from interference by a braided shield formed from spun yarn of nickel-plated carbon fiber surrounding and enveloping said conductor.
