Armored cable assembly with grounding path component equipped armor
An armored cable assembly with grounding path component equipped armor and a method of producing the same is provided. The armored cable includes an SZ cabled core having a binder tape wrapped conductor bundle that includes a first ground conductor. A second ground conductor is positioned outside the binder tape such that it is aligned with the longitudinal axis of the SZ cable core and contacts the interlock armor at each helical convolution.
1. An armored cable comprising:
an SZ cabled core comprising a conductor bundle wrapped in binder tape, the conductor bundle comprising a first ground conductor and a plurality of conductors, wherein a cable lay direction of the SZ cabled core changes at intervals along its full length;
a second ground conductor positioned outside the binder tape such that the second ground conductor stands above the SZ cabled core and is aligned with a longitudinal axis of the SZ cabled core; and
an interlocked armor formed from interlocked helical convolutions of a metallic strip disposed over the SZ cabled core and the second ground conductor such that the second ground conductor contacts the interlock armor at each helical convolution.
2. The armored cable of claim 1 , wherein the cable lay direction of the SZ cabled core changes at uniform intervals.
3. The armored cable of claim 1 , wherein the second ground conductor has a diameter that is greater than the diameter of the first ground conductor.
4. The armored cable of claim 1 , wherein the second ground conductor is a solid aluminum bond wire.
5. The armored cable of claim 1 , wherein the plurality of conductors comprises a control conductor assembly.
6. A method of assembling an armored cable, the method comprising:
SZ twisting a first ground conductor, a phase conductor, and a neutral conductor adjacent to each other to form an SZ cabled core, wherein a cable lay direction of the SZ cabled core changes at intervals along its full length;
wrapping a binder tape around the SZ cabled core;
positioning a second ground conductor outside the binder tape of the SZ cabled core such that the second ground conductor stands above the SZ cabled core and is aligned with a longitudinal axis of the SZ cabled core; and
covering the SZ cabled core and the second ground conductor with an interlock armor such that the second ground conductor contacts the interlock armor at each helical convolution of the interlock armor.
7. The armored cable of claim 5 , wherein the control conductor assembly comprises a first control conductor and a second control conductor.
8. The armored cable of claim 1 , wherein:
at a first position of the armored cable, the first ground conductor is positioned between the plurality of conductors and the second ground conductor,
at a second position of the armored cable, the plurality of conductors is positioned between the first ground conductor and the second ground conductor, and
at a third position of the armored cable between the first position and the second position, the second ground conductor is positioned within a valley between the first ground conductor and the plurality of conductors.
