Systems and methods for providing power to a device in a hydrocarbon development operation include a cable having a single core conductor. The single core conductor is an elongated member with a central axis and is operable to conduct electricity. An insulation member circumscribes the single core conductor and extends the length of the single core conductor. The insulation member has an annular cross section centered around the central axis of the single core conductor. An armor layer circumscribes the single core conductor and extends the length of the single core conductor. The armor layer has an annular cross section centered around the central axis of the single core conductor and is formed of a non-conductive material incapable of conducting a current. The armor layer is radially exterior of the insulation member.
