An electric wire conductor includes a wire strand having a plurality of elemental wires twisted together. The wire strand includes a deformed part in which a cross-section of the wire strand intersecting an axial direction of the wire strand is formed into a flat shape in which a width of the cross section is larger than a height of the cross section, and an entire outer periphery of the cross section is formed as an outward curve. In the cross-section of the deformed part, the elemental wires have deformation ratios from a circle of 70% or lower at an outer peripheral part facing the outer periphery of the deformed part than at a center part located inside the outer peripheral part.

Provided are multiply-insulated articles, comprising at least first and second containers disposed together such that the interior volume of the first container is sealed against the environment exterior to the article.

Compositions including a filler, an emissivity agent, a crosslinking facilitator, and a metal silicate binder are disclosed. The compositions can be curable at ambient conditions. Methods of coating overhead conductor and power transmission line accessories with such coating compositions are also disclosed.

An electric cable is providing having at least one elongated electrically conducting element containing a plurality of electrically conducting strands and at least one fluorinated polymer layer surrounding said elongated electrically conducting element, said cable further comprising a metallic layer comprising nickel interposed between the elongated electrically conducting element and the fluorinated polymer layer, and a method of manufacturing said cable.

An electric cable for supplying power to aircrafts, rail vehicles, motor vehicles, ships or other devices is a single or multi-conductor cable and includes one or more current conductors with at least one insulation. A single or multi-layer outer casing is distributed over the periphery and is associated with the outwardly protruding reinforcing elements. The reinforcing elements are in the form of cooling ribs protruding preferably over the entire periphery of the cable and enable the surface of the cable to be increased and as a result, improve heat dissipation. The projecting reinforcing elements considerably reduce the risk of burning when the current conductors heat up and also protect the cable against abrasion. The invention also relates to a plug for the electric cable.

An example cable assembly includes: a plurality of conductors in a Litz cable arrangement, in which each of the plurality of conductors is electrically insulated from each other over at least a portion of a length of the Litz cable arrangement; a first layer of insulation over the Litz cable arrangement; an inner dielectric jacket over the first layer of insulation; and an outer jacket over the inner dielectric jacket.

A power cable has a cable core with at least one conductor with an insulating system and a water barrier surrounding the cable core. The water barrier has a helically wound strength bearing layer interconnected by a low melting point material.

The communication cable includes a two-core communication line including two insulated electric wires each having a conductor and an insulator covering the conductor, a drain wire and a metal foil. The two-core communication line and the drain wire are collectively covered with the metal foil. The two insulated electric wires are twisted together. The insulator has a foaming ratio being equal to or smaller than 45%. The insulator may have the foaming ratio being equal to or greater than 28%. A wire harness may include the communication cable.
