A gas feeder pipe assembly includes a central duct capable of functioning as a gas feeder pipe and a plurality of pairs of electrical conductors in a unitary structure. The gas feeder pipe is located at the center of the structure, and the conductors surround the pipe in an oscillating lay. The pipe and the conductors are wrapped in a polyester film and enclosed in a coated aluminum sheath. A polyethylene jacket bonded to the aluminum sheath provides the outermost protection for the assembly.
