1. A current-carrying flexible hose comprising:
- (a) first and second parallel helical support members disposed in double lead fashion with successive convolutions alternating;
(b) an inner plastic strip wrapped helically about said support members with forward and rearward edge portions of said inner plastic strip overlapping convolutions of the second of said support members;
(c) an outer plastic strip wrapped helically about said inner plastic strip with forward and rearward edge portions of said outer plastic strip overlapping convolutions of the first of said support members; and
(d) at least one pair of helical electrical conductors disposed on opposite sides of one of said support members and slidably positioned between said inner and outer plastic strips, each of said helical electrical conductors comprising;
(i) a conductive elements; and
(ii) a dielectric plastic coating disposed around said conductive element.

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.
