HYBRID CABLE Russian patent published in 2012 - IPC E21B17/20 H01B9/00 F16L11/00 

FIELD: electricity.

SUBSTANCE: hybrid cable comprises several pipes for a fluid medium, electrical wires and/or optical conductors, a filling material, which are assembled together into a twisted bundle by means of a packing operation. The hybrid cable also comprises a protection shell covering the pipes for the fluid medium, the wires/conductors and the filling material, and at least one load-carrying element installed in a cross-section of the hybrid cable. The pipes for the fluid medium, the wires/conductors, the filling material and at least one load-carrying element are laid in turns, i.e. with a continuously varying direction along the entire length or on a part of the hybrid cable length. At the same time the assembled bundle shall be held as substantially rigid in torsion with the help of the protection shell, possibly, with addition of a strong tape wound along the spiral line onto the bundle directly under the protection shell.

EFFECT: simple manufacturing of a large-length cable with the help of a mobile small-size equipment, resistance to stretching forces in process of the cable installation.
