Abstract

A concentric three-conductor cable includes an inner conductor and outer conductors formed of braided strands, and insulating material separating the outer conductors from each other and from the inner conductor, each the other conductors being formed of a plurality of layers and the d-c resistance of the outer conductors being several times smaller than the d-c resistance of said inner conductor.
