1. A metal sheath for housing a plurality of conductors, the metal sheath comprising a continuous strip of metal having a plurality of revolutions extending along a lengthwise axis, a first revolution of the plurality of revolutions comprising:
a first section having a semicircular profile extending into an interior cavity of the metal sheath;
a second section extending from the first section, wherein a length of the second section is larger than a diameter of the first section; and
a third section extending from the second section, the third section terminating within a recess defined by a profile of a first section of an adjacent revolution of the plurality of revolutions,
wherein the first section and the second section of the first revolution connect at a first inflection point, wherein the second section and the third section of the first revolution connect at a second inflection 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 inflection point of the adjacent revolution, and wherein a distance between the second inflection point of the first revolution and the first inflection point of the adjacent revolution is less than the diameter of the first section of the first revolution, and wherein the length of the second section of the first revolution is at least two times as large as the distance between the second inflection point of the first revolution and the first inflection point of the adjacent revolution.
