An insulated electric wire that includes a conductor having a plurality of twisted elemental wires made of a conductive material and an insulation covering that covers an outer surface of the conductor. The method includes a partial exposure step of forming an exposed portion in which the insulation covering is removed from the outer surface of the conductor, a density modification step of increasing spacing between elemental wires in the exposed portion, while increasing a density of the conductive material per unit length in the exposed portion, and a filling step of filling gaps between the elemental wires in the exposed portion with a sealant comprising an insulated material.

The invention relates to a data cable. One embodiment of the data cable has at least one pair of wires and a cable sheath surrounding the at least one pair of wires. The at least one pair of wires has two wires twisted together in the longitudinal direction of the data cable. Cavities between the at least one pair of wires and the cable sheath are at least partially filled with a filler. The filler has a viscosity which is such that it adheres in the data cable in such a way as to remain in the data cable at least nearly completely when there is a specified pressure difference between one end of the data cable and the other end of the data cable.

A method for producing a surface finish on an electrically conductive substrate includes transferring an ink having a plurality of electrically conductive particles onto an area of a predetermined form and/or size on a surface of the electrically conductive substrate by gravure and/or flexo printing. The ink is heated to a temperature that is higher than a melting point of the electrically conductive particles to create a melt. The melt solidifies into the surface finish on the electrically conductive substrate.

In a method making a flexible electrical conductor, a mask layer (216) is applied to a substrate (210). A portion of the mask layer (216) is removed to expose the substrate (210) in an exposed shape (220) corresponding to the conductor. A liquid phase conductor (232) is applied to the portion of the substrate (210). The mask layer (216) is dissolved with a solvent (238) to leave a shaped liquid phase conductor (234) corresponding to the exposed shape on the substrate (210). A primary elastomer layer (240) is applied onto the substrate (210) and the shaped liquid phase conductor (234). The primary elastomer layer (240) and the shaped liquid phase conductor (234) are removed from the substrate (210). A secondary elastomer layer (242) is applied to the shaped liquid phase conductor (234) and the primary elastomer layer (240) to seal the shaped liquid phase conductor (234) therein.

A gas blocking cable includes cabled wires, where each wire includes cabled conductors having interstitial areas there between. An insulation material circumferentially surrounds the cabled conductors and a conductor filling material is positioned within the interstitial areas between conductors. A shield circumferentially surrounds the cabled wires so that a cable is formed with areas between the wires. A wire filling material is positioned within the areas between the wires. Each of the conductor filling material and wire filling material is inert, non-flammable and able to withstand a temperature of at least approximately 200 C.

The purpose of the present invention is to allow a water stop performance between electric wires to be maintained as much as possible even when the electric wires are bent. A water stop structure for an electric wire bundle includes an electric wire bundle in which a plurality of electric wires are bundled together, a filler with which gaps between the plurality of electric wires are filled while maintaining fluidity and viscosity in at least a portion of an extension direction of the electric wire bundle, and a covering body covering a circumference of the portion of the electric wire bundle filled with the filler.

Provided is a production method for an insulated electric wire that enables a sealant to permeate between elemental wires with efficiency and high uniformity when a water-stopping treatment is applied to the insulated electric wire using the sealant, and also provided is an insulated electric wire that exhibits an excellent water-stopping performance at a portion between the elemental wires where the water-stopping treatment is applied. The water-stopping treatment is applied to an insulated electric wire 1 containing a conductor 2 containing a plurality of twisted elemental wires made of a conductive material, and an insulation covering 3 covering the outer surface of the conductor 2 by performing: a partial exposure step of adjacently arranging an exposed portion 10 where the insulation covering 3 is removed from the outer surface of the conductor 2, and a covered portion 20 where the insulation covering 3 covers the outer surface of the conductor 2 along the longitudinal axis of the insulated electric wire 1; and a density modification step of increasing a spacing between the elemental wires of the exposed portion 10 while the density of the conductive material per unit length in the exposed portion 10 is increased; and a filling step of filling a gap between the elemental wires of the exposed portion 10 with a sealant 5 made of an insulated material.

A process for coloring post-production cables or coloring cables in an in-line manufacturing process can include coloring a polymer coated conductive cable or wire using a colorant solution. In one example, the wire can be passed through a trough, bath or spray of the colorant solution. In one example, the colorant can have a transparent characteristic to it in order to allow the printing on the cable to show through the colorant applied to the cable.
