An underfloor shielded harness (100) has a long conductive plate which is wound so as to have at least two internal spaces (104, 105) in a cross section taken perpendicularly to the longitudinal direction. High-voltage cables (102) is inserted in the internal space (104) of the conductive plate (103) and the low-voltage cable (101) is inserted in the internal space (105) that is different from the internal space (104) in which the high-voltage cables (102) is inserted. At least one of the two internal spaces (104, 105) communicates with the outside of the spaces (104, 105) formed by the conductive plate (103).

When an electric wire too separates from a ground portion electrically grounded, an electromagnetic wire released from the electric wire cannot be suppressed. A conductive member is arranged to contact the ground portion electrically grounded and the electric wire attached to the ground portion by a first attachment member and a second attachment member. The conductive member is arranged between the first attachment member and the second attachment member.

A self-supporting cable including an outer portion and an inner portion is provided, as well as a combination of a self-supporting cable and a suspension arrangement. The inner portion includes at least one insulated conductor and the outer portion includes a first inner surface and an external surface. The external surface is arranged to engage with a suspension arrangement. The inner portion includes a first outer surface, the first outer surface abutting against the first inner surface. The outer portion includes an outer layer and a metal tape adhered to the outer layer. The outer layer includes the external surface, and the metal tape includes the first inner surface. The first inner surface being of metal and adapted for, during local load, frictional engagement with the material of the first outer surface increases the effectiveness of a functional grip between first outer surface and first inner surface.

An insulated electric conductor and method for making such a conductor are disclosed. The conductor comprises a copper core, a layer of aluminum formed over the copper core, an aluminum oxide dielectric layer formed over the layer of aluminum, and a thin polymeric layer formed over the aluminum oxide dielectric layer. The thin polymeric layer is preferably between about 30 microns (0.001″) and about 500 microns (0.02″) and is more preferably between about 45 microns (0.0015″) and about 250 microns (0.01″). The polymeric layer may be any polymeric material selected from the group consisting of acrylic resins, epoxy resins, polyurethane resins, and silicone resins. Other polymeric materials may be used. The polymeric layer may be formed by a variety of methods including, but not limited to, spraying, brushing, dipping, and powder coating.

A method for manufacturing power cables may include: providing at least one insulated conductor; and/or arranging a water barrier around the at least one insulated conductor. Arranging the water barrier may include: providing foil having opposite edges; wrapping the foil around the at least one insulated conductor until the edges of the foil overlap; fastening the overlapped edges of the foil to each other with bonding agent to form a corresponding foil seam; and/or depositing a metal coating on the foil at the seam by a thermal spray process. A power cable may include: at least one insulated conductor; at least one first water barrier surrounding the at least one insulated conductor, the at least one first water barrier being wrapped foil having edges overlapped and fastened by bonding agent, the overlapped edges and bonding agent forming a foil seam; and/or a thermal sprayed metal coating on the seam.

A cable for integrated data transmission and power supply includes an insulative tube having a hollow chamber; an outer knitted shield disposed on an inner wall surface of the insulative tube; a first signal wire arranged inside the hollow chamber and including a plurality of first signal core lines and an inner knitted shield covering an outer thereof; a second signal wire penetrating through the hollow chamber and using the first signal wire as a center to be arranged at one side of the first signal wire; and a power wire penetrating through the hollow chamber and using the first signal wire as a center to be arranged at another side of the first signal wire and opposite from the second signal wire. Accordingly, the cable can be used for various different transmission interfaces while having a reduced cable diameter and saving the material used.
