Es wird ein Verfahren zum zugfesten Abschließen des Endes eines Energiekabels (4) angegeben, für welches ein Energiekabel (4) verwendet wird, dessen elektrische Übertragungselemente enthaltende Seele (5) von einer zugfesten, aus Metalldrähten bestehenden Bewehrung (6) umgeben ist. Zunächst wird die Bewehrung (6) am Ende des Energiekabels (4) auf einer vorgegebenen Länge entfernt. Danach wird auf das Ende der verbliebenen Bewehrung (6) ein dieselbe dicht umgebendes Rohrstück (7) aus Metall aufgebracht und zugfest mit derselben verbunden. Abschließend wird eine topfartige, rohrförmig langgestreckte Hülse (9) aus Metall auf das Ende des Energiekabels (4) aufgeschoben und zugfest mit dem Rohrstück (7) verbunden, die an ihrem freien, vom Rohrstück (7) wegweisenden Ende eine zum Anbringen eines Zugelements geeignete Einrichtung hat. Es wird außerdem eine mit dem Verfahren hergestellte Vorrichtung angegeben.

A braid having a function as an exterior member as well as an electromagnetic shielding function is provided. Also, a wire harness including such a braid in a configuration is provided. A braid is used for a wire harness cabled to a hybrid vehicle. Also, the braid is formed by knitting multiple ultrathin strands in a tubular shape. The braid includes two kinds of strands, a metal strand made of metal having conductivity and a resin strand made of synthetic resin having abrasion resistance etc., and ensures abrasion resistance and impact resistance by the portion made of the resin strand while performing an electromagnetic shielding function by the portion made of the metal strand.

The invention relates to the skin-effect based induction-resistive heating units and can be used in devices intended for prevention of paraffin-hydrate deposits formation in oil-and-gas wells and pipelines, as well as for warming up of viscous products in pipelines and vessels for the purpose of their transporting and pumping. The skin-effect based heating cable contains the center conductor, the inner insulation layer and the ferromagnetic outer conductor coaxially located around them. The inner insulation layer is made of a polymer material. The outer conductor is made in form of corrugated steel tube with the wall thickness less than three skin depths at the supply voltage operating frequency. The heating unit consists of a segment of the above described heating cable and a two-phase AC power source. The first output of the AC supply is connected to the proximal end of the center conductor and the second output - to the proximal end of the outer conductor. At that at the distal end of the said cable segment, the center and the outer conductors are connected to each other. The heating method consists in implementation of the heating with the use of the skin-effect in the outer conductor of the heating cable by applying the current from an industrial electric network to the input of the above described heating unit. The invention enables to simplify using due to increase of the heating cable flexibility and due to reduce the energy consumption at its operation.
