Abstract

A system for providing cable support may be provided. The system may comprise a conductor core, a filler that may provide integral core support, and armor. The conductor core may comprise at least one conductor. The filler may be applied around at least a portion of the conductor core. The armor may be applied around at least a portion of the filler. The applied armor may be configured to cause the filler to apply a strong enough force on an exterior of the conductor core configured to keep the conductor core from slipping down an interior of the filler due to a gravitational force. In addition, the applied armor may be configured to cause the filler to apply a strong enough force on an interior of the armor configured to keep a combination of the conductor core and the filler from slipping down the interior of the armor due to the gravitational force.

First claim

1 - 36 . (canceled)

37 . A method of supplying power in a multistory building, the method comprising installing an armored cable in a vertical orientation, wherein the armored cable comprises:
(a) a conductor core; (b) an integral support, wherein the integral support does not contain a tensile member; and (c) an armor layer.

38 . The method of claim 37 , wherein the armored cable is installed in the vertical orientation without the use of a horizontal offset.

39 . The method of claim 37 , wherein the conductor core comprises at least three conductors.

40 . The method of claim 39 , wherein the conductor core further comprises a ground wire.

41 . The method of claim 37 , wherein the armored cable further comprises a tape separator around the conductor core.

42 . The method of claim 37 , wherein the integral support comprises polyethylene, polyvinyl chloride (PVC), or nylon between the conductor core and the armor layer.

43 . The method of claim 42 , wherein the integral support further comprises microspheres dispersed throughout the integral support.

44 . The method of claim 42 , wherein the integral support comprises voids created by a foaming agent.

45 . The method of claim 37 , wherein the integral support is configured to prevent the conductor core from slipping within the armor layer due to a gravitational force.

46 . The method of claim 37 , wherein the armor layer is helically wound around the integral support.

47 . The method of claim 46 , wherein the outer surface of the integral support is substantially round prior to application of the armor layer.

48 . The method of claim 37 , wherein the armor is free of a jacket on the exterior of the armor.

49 . A method of supplying power in a multistory building, the method comprising installing an armored cable in a vertical orientation, wherein the armored cable consists essentially of:
(a) a conductor core; (b) an integral support; and (c) an armor layer around the integral support.

50 . The method of claim 49 , wherein the armored cable is installed in the vertical orientation without the use of a horizontal offset.

51 . The method of claim 49 , wherein the conductor core comprises at least three conductors, an optional ground wire, and an optional tape separator.

52 . The method of claim 49 , wherein the integral support comprises polyethylene, polyvinyl chloride (PVC), or nylon between the conductor core and the armor layer.

53 . The method of claim 52 , wherein the integral support further comprises microspheres dispersed throughout the integral support.

54 . The method of claim 49 , wherein:
the conductor core comprises two or more conductors and a ground wire adjacent at least one of the conductors; and the integral support comprises polyvinyl chloride (PVC) and microspheres.

55 . A method of producing a cable with integral support, the method comprising:
applying a filler around at least a portion of a conductor core to provide integral core support, wherein the conductor core comprises at least one conductor; and applying armor around at least a portion of the filler, the applied armor configured to cause the filler to apply a strong enough force on an exterior of the conductor core to keep the conductor core from slipping down an interior of the filler due to a gravitational force when the cable is oriented vertically.

56 . The method of claim 55 , wherein the applied armor is further configured to cause the filler to apply a strong enough force on an interior of the armor to prevent a combination of the conductor core and the filler from slipping down the interior of the armor due to a gravitational force when the cable is oriented vertically.
