Single motor power and communication cable

摘要

A combined power and communications cable for use with a motor and drive unit in an industrial control system is provided. The cable may comprise first, second and third insulated conductors twisted together and covered by a cable jacket (first group); fourth and fifth insulated conductors twisted together and covered by an electrical shield (second group); and a sixth insulated conductor for delivering a protective ground (third group). The first, second and third groups are twisted together, covered by an electrical shield and covered by a cable jacket. Filler may be formed around the fourth and fifth insulated conductors, and may be formed around the first, second and third groups, to substantially maintain round geometric shapes.
