Abstract

An electrical cable assembly, comprising a first electrical circuit further comprising a first plurality of insulated conductors longitudinally disposed to one another, wherein the first plurality of insulated conductors are cabled together in a bundle. The electrical cable assembly further comprises a second electrical circuit longitudinally disposed to the first electrical circuit, the second electrical circuit comprising a second plurality of insulated conductors longitudinally disposed to one another and cabled together in a bundle and a nonmetallic jacket surrounding the second plurality of insulated conductors and wherein the nonmetallic jacket isolating the first electrical circuit from the second electrical circuit. The electrical cable assembly further comprises a flexible interlocking metallic armor encasing the first and second electrical circuits.

First claim

What is claimed is:

1. An electrical cable assembly, comprising:
a first electrical circuit comprising a first plurality of insulated conductors;
a second electrical circuit comprising:
a plurality of control insulated conductors;
a nonmetallic jacket surrounding the plurality of control insulated conductors, the nonmetallic jacket isolating the first electrical circuit from the second electrical circuit; and

a flexible interlocking conductive metallic armor encasing the first and second electrical circuits, wherein the flexible interlocking conductive metallic armor provides a return ground path.

2. The electrical cable assembly of claim 1 , wherein the first plurality of insulated conductors include solid copper conductors.

3. The electrical cable assembly of claim 1 , wherein the first plurality of insulated conductors include stranded copper conductors.

4. The electrical cable assembly of claim 1 , wherein the first plurality of insulated conductors are power supply insulated conductors.

5. The electrical cable assembly of claim 1 , wherein the plurality of control insulated conductors are signal insulated conductors.

6. The electrical cable assembly of claim 1 further comprising color-coded labels applied to the flexible interlocking metallic armor.

7. The electrical cable assembly of claim 1 , wherein the flexible interlocking metallic armor is formed from aluminum.

8. The electrical cable assembly of claim 1 , wherein the flexible interlocking metallic armor is formed from steel.

9. The electrical cable assembly of claim 1 , wherein the flexible interlocking metallic armor is coated with polyvinyl chloride (PVC).

10. The electrical cable assembly of claim 1 , wherein the plurality of control insulated conductors are helically twisted about one another.

11. The electrical cable assembly of claim 1 , wherein the nonmetallic jacket is formed from polyvinyl chloride (PVC).

12. The electrical cable assembly of claim 1 , wherein the first plurality of insulated conductors includes at least three insulated conductors.

13. The electrical cable assembly of claim 12 , wherein the at least three insulated conductors includes an insulated ground conductor.

14. The electrical cable assembly of claim 1 , wherein the first plurality of insulated conductors includes at least five insulated conductors.

15. The electrical cable assembly of claim 1 , wherein the first plurality of insulated conductors includes thermoplastic high heat-resistant Nylon-coated insulated conductors.

16. The electrical cable assembly of claim 1 , wherein the first plurality of insulated conductors includes thermoplastic heat and moisture resistant Nylon-coated insulated conductors.

17. The electrical cable assembly of claim 1 , wherein the plurality of control insulated conductors includes at least two insulated conductors.

18. The electrical cable assembly of claim 17 , wherein the plurality of control insulated conductors includes thermoplastic flexible Nylon-coated insulated conductors.

19. The electrical cable assembly of claim 1 further comprising a separator tape surrounding the first and second electrical circuits and located within the flexible interlocking metallic armor.

20. The electrical cable assembly of claim 19 , wherein the separator tape includes printed conductor identification information.
