Abstract

An electrical cable having a shielding comprised of knit or knit-graded wire having metal coatings.

Claims

1. An electrical cable, comprising

an electrically insulating sheath,

a plurality of insulated electrical conductors mounted within said sheath, and

shielding made from wire that is knit with said wire in the form of an integral sleeve encompassing said sheath, said wire having a steel core, a first coating of metal of greater conductivity than said steel core and a second coating of a metal having greater lubricity than the first coating.

2. An electrical cable, comprising

an electrically insulating a sheath,

a plurality of insulated electrical conductors mounted within said sheath, and

shielding made from wire that is knit-braided with said wire in the form of an integral sleeve encompassing said sheath, said wire having a steel core, a first coating of metal of greater conductivity than said steel core and a second coating of a metal having greater lubricity than the first coating.

3. An electrical cable as set forth in claim 2 wherein said first coating is copper and said second coating is silver or tin.
