A communications cable is described. The communications cable can include a cable jacket, a separator structure that defines one or more channels for receiving at least one communications medium, and an insulator that surrounds the communications medium. The cable jacket can include one or more corrugations on at least one of its interior or exterior surfaces. The separator can also include one or more grooves on at least a portion of its surface. The insulator can also include one or more indentations on at least one of its interior or exterior surfaces. The corrugations, grooves, and indentations can extend along the longitudinal length of the cable and define one or more air channels for forwarding and circulating air through or on the surface the cable. The circulation of air in the cable can reduce the temperature of the cable and increase the quality of the signal transmitted through the cable.

The present disclosure provides a coated conductor. The coated conductor includes a conductor and a coating on the conductor. The coating includes (i) an annular wall composed of a polymeric material, the annular wall surrounding at least a portion of the conductor; (ii) a plurality of channels extending along a length of an outer surface of the annular wall; and (iii) a slip material located in the channels, the slip material forming a capillary structure in the channels, and the capillary structures protruding radially outward from the annular wall.

A flex flat cable (FFC) structure includes metallic transmission wires arranged in parallel, first insulating jackets, and second insulating jacket. The metallic transmission wires includes one or more power wires and signal wires. The power wire is configured to transmit power. The signal wires are configured to transmit a data signal. Each of first insulating jackets encloses one of metallic transmission wires. The second insulating jacket surrounds the first insulating jackets. An embossment pattern is arranged on an external surface of the second insulating jacket. The embossment pattern includes meander lines in a top-view direction and in an extending direction for the metallic transmission wires. The meander lines are not arranged parallel.

A core which is clamped together with an electric wire protection tube in a molding die when molding a molded portion, in a molding device for clamping a part of the electric wire protection tube which is hollow cylindrical shaped with the molding die and molding the molded portion on an outer peripheral side of the electric wire protection tube, with respect to the electric wire protection tube which is formed with a slit in a longitudinal direction, the core including a core main body portion which has a rod shape and is accommodated in the electric wire protection tube; and a protruding piece portion which is projected on a portion of an outer peripheral surface of the core main body portion, the portion being to be clamped by the molding die, and protruding from the slit of the electric wire protection tube.

A system for providing cable support may be provided. The system may comprise a conductor core, a filler that may provide integral core support, and armor. The conductor core may comprise at least one conductor. The filler may be applied around at least a portion of the conductor core. The armor may be applied around at least a portion of the filler. The applied armor may be configured to cause the filler to apply a strong enough force on an exterior of the conductor core configured to keep the conductor core from slipping down an interior of the filler due to a gravitational force. In addition, the applied armor may be configured to cause the filler to apply a strong enough force on an interior of the armor configured to keep a combination of the conductor core and the filler from slipping down the interior of the armor due to the gravitational force.

A flex flat cable (FFC) structure includes metallic transmission wires arranged in parallel, first insulating jackets, and second insulating jacket. The metallic transmission wires includes one or more power wires and signal wires. The power wire is configured to transmit power. The signal wires are configured to transmit a data signal. Each of first insulating jackets encloses one of metallic transmission wires. The second insulating jacket surrounds the first insulating jackets. An embossment pattern is arranged on an external surface of the second insulating jacket. The embossment pattern includes meander lines in a top-view direction and in an extending direction for the metallic transmission wires. The meander lines are not arranged parallel.

A current bar for a connection terminal comprises a first connection region and a second connection region which is galvanically connected to the first connection region. The current bar comprises a conductor support by which means the first connection region is galvanically connected to the second connection region, a main material constituent of the conductor support being aluminum and an electroconductive covering layer being arranged on the conductor support, an electroconductive intermediate layer being sandwiched between the conductor support and the covering layer.

A method for producing an elongated article with a sheath. The sheath is extruded with a predetermined wall thickness in an extrusion unit. Following the extrusion unit in a feeding direction, a part of the still moldable material is built up with the aid of a molding unit during a molding process such that a molded part forms integrally on the sheath. The molding unit is moved according to the following working cycle: the molding unit is accelerated from a starting position in the feeding direction, then it is advanced in the direction of the elongated article and the molded part is formed, the molding unit is withdrawn from the elongated article, and the molding unit is decelerated and moved from an end position, counter to the feeding direction, back in the direction of the starting position.

The present disclosure provides a conduit (10). The conduit (10) includes (i) an annular wall (66) composed of a polymeric material, the annular wall (66) defining an annular passageway; (ii) a plurality of channels (68) extending along a length of an inner surface (62) of the annular wall (66); and (iii) a slip material located in the channels (68), the slip material forming a capillary structure (70) in the channels (68), and the capillary structures (70) protruding radially inward from the annular wall (66).

A method for producing an electrical conductor may include cutting an electrically conductive round wire composed of copper to a predefined desired length and plastically forming the round wire, in at least one forming section, into a predefined desired shape.
