    摘要： A flexible coaxial cable includes a core including at least one inner conductor and a foam polymer dielectric surrounding the inner conductor. The flexible coaxial cable also includes an electrically and mechanically continuous tubular copper sheath closely surrounding the core and adhesively bonded to the core. A protective outer jacket surrounds the tubular metallic sheath and is adhesively bonded to the tubular metallic sheath to increase the bending properties of the cable. The bond peel strength of the adhesive bond between the polymer jacket and the sheath is no more than 36 lb./in to provide a coaxial cable having excellent bending characteristics and which can be easily stripped to provide an electrical connection between the coaxial cable and other conductive elements. The present invention also includes a method of making flexible coaxial cable.

    摘要： A method for producing a sector conductor for electric power cables is introduced, whereby a number of metal wires are joined closely together into a core (8) with a sector-shaped cross section. A lengthwise running metal strip is formed around the core (8) and its longitudinally abutting edges are welded into a tube (9), whose dimensions are reduced so that it lies closely against the core (8) and surrounds it.

    摘要： A method of making a flexible coaxial cable is provided. The method comprises advancing a cable core comprising a conductor and an expanded foam dielectric surrounding the conductor along a predetermined path of travel, directing an elongate strip of copper onto the advancing cable core and bending the copper strip into a generally cylindrical form so as to loosely encircle the core. Opposing longitudinal edges of the thus formed copper strip are then moved into abutting relation and a longitudinal weld is formed joining the abutting edges to thereby form an electrically and mechanically continuous tubular copper sheath loosely surrounding the cable core. The cable core and the surrounding sheath are simultaneously advanced while the tubular sheath is deformed into an oval configuration loosely surrounding the core. The longitudinal weld of the advancing sheath is then directed against a scarfing blade and weld flash from the sheath is scarfed from the sheath. The advancing copper sheath is sunk onto the advancing cable core to form the coaxial cable. A polymer composition may be extruded around the copper sheath to form a protective jacket surrounding the coaxial cable and may be bonded thereto. The present invention also includes a flexible coaxial cable having excellent electrical and bending properties.

    摘要： A method of producing a copper clad steel wire, which comprises the steps of preparing a 5 to 15 mm diameter steel rod and a 21 to 66.7 mm width copper tape; continuously supplying the steel rod and the copper tape separately and cleaning the surfaces thereof; forming the copper tape in tubular form such that the copper tape can cover the steel rod while supplying the steel rod and the copper tape in parallel, and welding the edges of the copper tape in a non-oxidizing atmosphere; sinking the tubular copper tape sufficiently for the copper tape to substantially come into contact with the steel rod to form a copper clad steel rod; cold-drawing the copper clad steel rod and/or hot working the clad rod at a temperature of 400.degree. to 800.degree. C. to reduce its cross-sectional area by more than 20%; and then annealing the copper clad steel rod at a temperature of 300.degree. to 1050.degree. C.
