20130240237 | METAL SHEATHED CABLE ASSEMBLY WITH NON-LINEAR BONDING/GROUNDING CONDUCTOR - A Metal-Clad cable includes at least two conductor assemblies and a non-linear bonding/grounding conductor within a metal sheath. Each conductor assembly has an electrical conductor, an insulation layer extending around and along the length of each of the electrical conductors, a jacket layer disposed around the insulating layer and a polymeric protective layer disposed around the jacket layer along the length of each of the electrical conductors. The bonding/grounding conductor includes a plurality of undulations disposed along a length thereof, and is disposed within the metal sheath so that it is in contact with an interior surface of the metal sheath. The bonding/grounding conductor is in cabled relation with the conductor assemblies. The undulations of the bonding/grounding conductor provide a degree of resiliency to the connection between the conductors and the metal sheath to facilitate easy removal of the metal sheath when making terminal connections. | 09-19-2013 |
20120073855 | METAL SHEATHED CABLE ASSEMBLY - A Metal-Clad cable that includes at least two conductor assemblies within a metal armored sheath. Each conductor assembly has an electrical conductor, an insulation layer extending around and along the length of each of the electrical conductors, a jacket layer disposed around the insulating layer and a polymeric protective layer disposed around the jacket layer along the length of each of the electrical conductors. A grounding/bonding strip is disposed within the cable and is in intimate contact with an interior surface of the metal sheath. If a grounding conductor is used, it is either in cabled relationship with the two conductor assemblies or is disposed along the length of the electrical conductors and the metal sheath is disposed over the at least two conductor assemblies and the grounding conductor. | 03-29-2012 |
20110011614 | TREATED ELECTRICAL CABLE - Improved electrical cables employ a protective material thereon for antimicrobial prevention. The electrical cable is formed by a metallic strip helically wound with interlocking edges to define an armor having an inner hollow area within which is housed a plurality of electrical conductors. The armor is treated with a coating which may be used for corrosion protection. The coating is treated with an antimicrobial and/or antifungal additive inhibiting the proliferating or these microorganisms on the cable. | 01-20-2011 |
20110011613 | TREATED ELECTRICAL CONDUIT - 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. | 01-20-2011 |
20090250239 | METAL SHEATHED CABLE ASSEMBLY - An AC cable that includes at a plurality of conductor assemblies within a metal armored sheath. Each conductor assembly has an electrical conductor, an insulation layer extending around and along the length of each of the electrical conductors, a jacket layer disposed around the insulating layer and a polymeric protective layer disposed around the jacket layer along the length of each of the electrical conductors. A bonding strip is disposed within the metal sheath and is in contact with the interior surface of the metal sheath to provide an electrical low-impedance fault return path for the AC cable. | 10-08-2009 |
20090250238 | METAL SHEATHED CABLE ASSEMBLY - A Metal-Clad cable that includes at least two conductor assemblies within a metal armored sheath. Each conductor assembly has an electrical conductor, an insulation layer extending around and along the length of each of the electrical conductors, a jacket layer disposed around the insulating layer and a polymeric protective layer disposed around the jacket layer along the length of each of the electrical conductors. A grounding/bonding strip is disposed within the cable and is in intimate contact with an interior surface of the metal sheath. If a grounding conductor is used, it is either in cabled relationship with the two conductor assemblies or is disposed along the length of the electrical conductors and the metal sheath is disposed over the at least two conductor assemblies and the grounding conductor. | 10-08-2009 |
20090188694 | FLEXIBLE CONDUIT WITH VISUAL IDENTIFICATION - An electrical conduit having a flexible metal tubular structure having an outer sheathing and an interior hollow area. An electrical conductor is housed in the interior hollow area. A visible indicia is applied to the outer sheathing and extends along at least a portion of the metal tubular structure where the visible indicia corresponds to at least one characteristic of the conduit or electrical conductor housed therein. | 07-30-2009 |
