Abstract

An improved electrical conduit having a protective material thereon for anti-microbial and antifungal prevention. The metallic conduit includes a metal armor defining an outer surface and an interior hollow area within which electrical conductors are disposed. A first polymeric layer is formed over the outer surface of the metal armor. A second polymeric layer is extruded over the first polymeric layer. The first and/or second polymeric layers may be formed with an anti-microbial and/or anti-fungal additive. In addition, the first polymeric layer may have a first color and the second polymeric layer may have a second color where the first color is different from the second layer sufficient for the first color to be visible when the second polymeric layer is compromised.

Claims (40)

1 . An electrical conduit comprising:

a flexible metal armor having an outer surface and defining an interior hollow area, said inner hollow area configured to house one or more electrical conductors;

a first polymeric layer disposed on said outer surface of said flexible metal sheathing, said first layer having a first color; and

a second polymeric layer disposed on said first polymeric layer, said second layer having a different color than said first layer such that said first layer is visible when said second layer is compromised, said first and second polymeric layers configured to prevent ingress of liquid within said conduit.

2 . The electrical conduit of claim 1 wherein the flexible metal tubular structure comprises a steel composition.

3 . The electrical conduit of claim 1 wherein said flexible metal tubular structure comprises a metal strip helically wound with interlocking edges.

4 . The electrical conduit of claim 1 wherein said first polymeric layer is extruded with an anti-fungal material.

5 . The electrical conduit of claim 1 wherein said second polymeric layer is extruded with an anti-fungal material.

6 . The electrical conduit of claim 1 wherein said first polymeric layer is extruded with an anti-microbial material.

7 . The electrical conduit of claim 1 wherein said second polymeric layer is extruded with an anti-microbial material.

8 An electrical conduit comprising:

a flexible metal armor having an outer surface and defining an interior hollow area, said inner hollow area configured to house one or more electrical conductors;

a first polymeric layer disposed on said outer surface of said flexible metal armor, said first layer having a first color; and

a second polymeric layer disposed on said first polymeric layer such that said first and second polymeric layers are configured to prevent ingress of liquid within said conduit, said second polymeric layer is extruded with an anti-microbial additive.

9 . The electrical conduit of claim 8 wherein said flexible metal tubular structure comprises a metal strip helically wound with interlocking edges.

10 . The electrical conduit of claim 8 wherein said first polymeric layer includes an anti-microbial additive.

11 . The electrical conduit of claim 8 wherein said first polymeric layer includes an anti-fungal additive.

12 . The electrical conduit of claim 8 wherein said second polymeric layer includes an anti-fungal additive.

13 . An electrical conduit comprising:

a polymeric rigid helix defining an outer surface and an interior hollow area, said interior hollow area extending longitudinally the length of said conduit and configured to house one or more electrical conductors; and

a substantially flexible polymeric layer disposed on said outer surface of said polymeric helix, said flexible polymeric layer having an anti-microbial additive.

14 . The electrical conduit of claim 13 wherein said flexible polymeric layer includes an antifungal additive.

15 . A method of manufacturing an electrical conduit comprising:

supplying a metal strip into a profiling die to form arcuate members;

supplying the arcuate members to an interlocking tool configured to interlock the respective edges of the arcuate members to form an outer armor;

forming a first polymeric layer having a first color over said outer armor; and

forming a second polymeric layer on the first polymeric layer, said second polymeric layer having a second color different from said first color.

16 . The method of manufacturing electrical conduit of claim 15 further comprising adding an anti-fungal composition to the first polymeric layer.

17 . The method of manufacturing electrical conduit of claim 15 further comprising adding an anti-fungal composition to the second polymeric layer

18 . The method of manufacturing electrical conduit of claim 15 further comprising adding anti-microbial protection to the first polymeric layer.

19 . The method of manufacturing electrical conduit of claim 15 further comprising adding anti-microbial protection to the second polymeric layer.

20 . A method of manufacturing an electrical conduit comprising:

supplying a metal strip into a profiling die to form a plurality of arcuate members;

supplying each arcuate member to an interlocking tool configured to interlock the respective edges of the arcuate members to form an outer armor having an outer surface and an interior hollow area; and

forming a polymeric layer over said outer surface of said protective armor wherein said polymeric layer is formed with an anti-microbial additive.

21 . The method of manufacturing an electrical conduit of claim 20 wherein said polymeric layer is formed with an antifungal additive.

22 . An electrical conduit comprising:

a flexible polymeric tube having a corrugated outer surface and a smooth or corrugated inner surface, said inner surface defining an interior hollow area configured to house one or more electrical conductors, said flexible polymeric having an antimicrobial additive.

23 . An electrical conduit comprising:

a flexible polymeric tube having a corrugated outer surface and a smooth or corrugated inner surface, said inner surface defining an interior hollow area configured to house one or more electrical conductors, said flexible polymeric having an antifungal additive.
