    摘要： Disclosed is an opto-electric cable comprising one or more electrical conductors, wherein each conductor comprises an electrically conductive core and an electrically insulating layer surrounding it. The cable also comprises an optical unit embedded within one of the electrically conductive cores. The optical unit comprises at least two optical fibres (each optical fibre comprising a core, a cladding and a coating) and a single buffer jointly surrounding all the optical fibres. Since all the optical fibres of the optical unit are jointly surrounded - and protected - by a single buffer, an optical unit with a reduced size is obtained. This allows reducing the cross section of the electrical conductor in which the optical unit is arranged. In particular, electrical conductors with cross section lower than 10 mm 2 are obtained.

    摘要： A waterproofing structure in a core wire includes a covered electric wire in which a plurality of core wires are covered with an insulating covering, a core wire bundle expanded portion in which the core wires of an intermediate core wire exposed portion are separated from each other and expanded in diameter by removing a part of the insulating covering, and a mold portion that is molded to surround the core wire bundle expanded portion by cooling and solidifying a thermoplastic adhesive filling between the core wires in the core wire bundle expanded portion by hot melting, together with the insulating coverings at both sides between which the intermediate core wire exposed portion is interposed.

    摘要： A method for enhancing the dielectric properties of an electrical cable segment having a central stranded conductor encased in a polymeric insulation jacket and an interstitial void volume in the region of the conductor, including filling the interstitial void volume with a dielectric property-enhancing fluid at a pressure below the elastic limit of the polymeric insulation jacket, and confining the fluid within the interstitial void volume at a residual pressure greater than about 50 psig, with the pressure being imposed along the entire length of the segment but below the elastic limit of the polymeric insulation jacket. Preferably, the residual pressure is sufficient to expand the interstitial void volume along the entire length of the cable segment by at least 5%.
