Abstract: A system for suspending and powering an electrically-powered fixture, such as a luminaire, with a coaxial suspension cable, and for attaching the fixture to the cable and to a structure, such as a ceiling, using at least one cable gripping devices, such that the height of the fixture may be adjusted. The suspension cable may comprise an inner cable, which may include a plurality of strength strands wound around a conductive strand; and an outer conductor, such as a copper mesh, separated from the inner cable by an insulator layer. The system may include an assembly mounted to the structure and an assembly mounted to the fixture, each assembly configured to grip the inner cable at one end of the suspension cable and to allow a first conductive path to the inner cable and a second conductive path, insulated from the first conductive path, along the outer conductor.

Abstract: A low voltage cable for providing low voltage power to an electrically-powered assembly, such as a luminaire fixture, and for attaching the luminaire fixture to the cable and to structure using a cable gripping device in such a way that the assembly can be adjusted, is disclosed. The cable comprises a conductive strand composed of a first metallic material, and a plurality of strength strands wound around the conductive strand, where the plurality of strength strands is of a second metallic material. The first metallic material is substantially more conductive than the second metallic material, and the second metallic material has substantially greater tensile strength than the first metallic material. This allows the cable to conduct a low voltage feed across the conductive strand, and allows the strength strands cable to mostly support the tension load particularly of a hanging luminaire fixture as well as resisting lateral compressive forces from a cable gripping device.

Abstract: A slip-ring device includes a cable, a stop-sleeve, a cable coupler, and a slip-ring. Preferably, the stop-sleeve is coupled to the cable. The cable coupler includes a hollow portion that can pass the cable and a surface having an opening sized to restrict an axial movement of the stop-sleeve. A slip-ring is coupled to the outer circumference of the hollow portion. A method of mounting a fixture to an enclosure includes inserting a portion of the cable through the cable coupler; coupling the cable coupler to the enclosure; positioning a canopy over the stem of the cable coupler; and fastening the canopy to the enclosure by threading the slip-ring to the cable coupler.
