ABSTRACT:
A current-carrying flexible hose having at least two parallel helical support wires, inner and outer plastic strips wrapped helically about the support wires, and at least one pair of helical electrical conductors disposed on opposite sides of one of the support wires and slidably positioned between the inner and outer plastic strips. Each of the helical electrical conductors comprises a conductive element and a plastic dielectric coating disposed around the conductive element. The plastic dielectric coatings are not bonded to the inner and outer plastic strips so that they may slide therebetween.
