A cable includes an insulating part and one or more conducting parts disposed inside the insulating part. The insulating part includes a polymer resin layer with a product of shrinkage ratios C.sub.MD*TD, which is expressed as a product of a longitudinal shrinkage ratio and a transverse shrinkage ratio, of less than 0.24.

There is provided a method of producing a long body covered with a covering layer, in which the long body includes at least plural electric wires and/or tubes, the covering layer includes at least a specific intermediate layer and a specific outermost layer, the method including at least: covering the long body with the covering layer; and fixing positions of the plural electric wires and/or tubes.

An electrical cable comprising four copper layers, where at least two of the four copper layers are separated by a polymeric base layer, and where at least two of the four copper layers are separated by an adhesive. The electrical cable further comprising a polymeric cover layer adhered to an outermost copper layer

The wiring member includes a wiring body and a shape maintaining member. The wiring body includes a sheet-like member and a wire-like transmission member fixed on the sheet-like member. The shape maintaining member is formed into a sheet-like shape having higher stiffness than the sheet-like member and covers at least one side of the wiring body along a front-back direction of the wiring body to maintain a shape of the wiring body.

A ribbon cable is described, including a first insulative layer extending along a length and a width of the cable, and a plurality of spaced apart substantially parallel conductors extending along the length of the cable. The insulative layer has opposing top and bottom major surfaces and defines a plurality of spaced apart cavities extending between the top and bottom major surfaces of the first insulative layer. The top major surface of the first insulative layer is deformed in a plurality of spaced apart substantially parallel regions extending along the length, and arranged along the width, of the cable. Each deformed region has a shape of a groove and includes a deformed portion of at least one cavity in the plurality of cavities. Each conductor is disposed within a corresponding deformed region of the insulative layer.

Provided herein are systems and methods for manufacturing a cable. In some embodiments, a system for manufacturing a cable includes a joining mechanism configured to join the upper conducting foil and the lower conducting foil; and a linear actuator configured to control motion of the joining mechanism with respect to the upper conducting foil and the lower conducting foil. In some embodiments, a system for manufacturing a cable includes: an electrode configured to join the upper conducting foil and the lower conducting foil in a region between insulated conductors of the plurality of insulated conductors; and a plurality of rollers configured to position the upper conducting foil, the lower conducting foil, and the plurality of insulated conductors relative to the electrode.

A shielded electrical cable includes conductor sets extending along a length of the cable and spaced apart from each other along a width of the cable. First and second shielding films are disposed on opposite sides of the cable and include cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the films in combination substantially surround each conductor set. An adhesive layer bonds the shielding films together in the pinched portions of the cable. A transverse bending of the cable at a cable location of no more than 180 degrees over an inner radius of at most 2 mm causes a cable impedance of the selected insulated conductor proximate the cable location to vary by no more than 2 percent from an initial cable impedance measured at the cable location in an unbent configuration.

A flexible flat cable includes a low-dielectric adhesive layer, a plurality of conductors, two shielding layers and two insulating protective layers. These conductors are located inside the low-dielectric adhesive layer and are spaced apart. The two shielding layers are laminated individually to the upper and lower surfaces of the low-dielectric adhesive layer. The two insulating protective layers are laminated individually to the two shielding layers.

The wiring member includes a wiring body and a shape maintaining member. The wiring body includes a sheet-like member and a wire-like transmission member fixed on the sheet-like member. The shape maintaining member is formed into a sheet-like shape having higher stiffness than the sheet-like member and covers at least one side of the wiring body along a front-back direction of the wiring body to maintain a shape of the wiring body.

The present disclosure provides an electric cable, comprising two signal conductors, a resin insulating layer, an expanded polytetrafluoroethylene insulating film, an electromagnetic shielding film, two ground conductors, and a covering layer. The resin insulating layer covers the two signal conductors. The expanded polytetrafluoroethylene insulating film covers the resin insulating layer. The electromagnetic shielding film covers the expanded polytetrafluoroethylene insulating film. The two ground conductors are disposed at two sides of the electromagnetic shielding film. The cladding layer dads the electromagnetic shielding film and the two ground conductors. Through the expanded polytetrafluoroethylene insulating film, the electric cable can be applied to compact products, and the electric cable can be highly flexible such that the signal transmission performance would not be affected after being repeatedly bent.
