1. A metal sheath for housing a plurality of conductors, the metal sheath comprising a plurality of revolutions extending along a lengthwise axis, a first revolution of the plurality of revolutions comprising:
a first section having a curved profile extending into an interior cavity of the metal sheath;
a second section extending from the first section, wherein the second section extends non-parallel with the lengthwise axis; and
a third section extending from the second section, the third section terminating within a recess defined by a semicircular profile of a first section of an adjacent revolution of the plurality of revolutions such that the first revolution and the adjacent revolution interlock,
wherein the first section and the second section of the first revolution connect at a first point, wherein the second section and the third section of the first revolution connect at a second point, wherein the adjacent revolution has a second section extending from the first section, wherein the first section and the second section of the adjacent revolution connect at a first point of the adjacent revolution, wherein a distance between the second point of the first revolution and the first point of the adjacent revolution defines a valley, wherein the valley is open to an exterior of the metal sheath, and wherein the distance between the second point of the first revolution and the first point of the adjacent revolution is less than the diameter of the first section of the first revolution when the metal sheath is in a linear configuration.
