Cable with spaced helices

摘要

A flexible and limp cable (1) is constructed with: an outer jacket (2) containing at least one row of adjacent insulated conductors (3) circumferentially encircling an elongated axis lengthwise of the cable (1), and conductive drain wires (4) in selected interstitial spaces along the adjacent insulated conductors (3), the insulated conductors (3) and the drain wires (4) extending helically along the axis, and a conductive membrane (7) circumferentially enclosing the insulated conductors (3) and the drain wires (4), and the membrane (7) engaging the drain wires (4).
