Abstract

An electrical cable assembly comprising a first electrical circuit comprising at least two insulated conductors, a second electrical circuit, and a conductive metallic armor encasing the first and second electrical circuits, wherein the conductive metallic armor provides a return ground path. The second electrical circuit comprising at least two control insulated conductors, a jacket surrounding the control insulated conductors, and a wrap surrounding the jacket which is surrounding the control insulated conductors.

Claims (25)

1. An electrical cable assembly, comprising:

a control electrical circuit comprising:

a control insulated conductor;

a jacket surrounding the control insulated conductor;

a wrap surrounding the jacket which is surrounding the control insulated conductor; and

a conductive metallic armor encasing the control electrical circuit, wherein the conductive metallic armor provides a return ground path.

2. The electrical cable assembly of claim 1 , wherein the wrap is helically encasing the jacket.

3. The electrical cable assembly of claim 1 , wherein the wrap is longitudinally encasing the jacket.

4. The electrical cable assembly of claim 1 , wherein the control insulated conductor is a thermoplastic flexible Nylon-coated insulated conductor.

5. The electrical cable assembly of claim 1 , wherein the control insulated conductor is a signal insulated conductor.

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

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

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

9. The electrical cable assembly of claim 8 , wherein the steel metallic armor is formed from galvanized steel.

10. The electrical cable assembly of claim 1 , wherein the control insulated conductor includes two control insulated conductors.

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

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

13. The electrical cable assembly of claim 1 , wherein the wrap is a shield.

14. The electrical cable assembly of claim 1 , wherein the wrap is formed from plastic.

15. The electrical cable assembly of claim 1 , wherein the wrap is formed from Mylar.

16. The electrical cable assembly of claim 1 , wherein the wrap is a tape.

17. The electrical cable assembly of claim 1 , wherein the wrap is a separator tape.

18. The electrical cable assembly of claim 1 further comprising a separator tape surrounding the control insulated conductor, the jacket surrounding the control insulated conductor, and the wrap.

19. The electrical cable assembly of claim 18 , wherein the separator tape is located within the metallic armor.

20. The electrical cable assembly of claim 18 , wherein the separator tape is printed with conductor identification information.
