摘要： A cable insulated with a cross-linked polyethylene layer is described, wherein the cross-linked polyethylene is prepared by cross-linking with 2,5-dimethyl-2-5-di(tert-butylperoxy)hexane or 2,5-dimethyl-2,5-di(tert-butylperoxy)hexyne-3 as a cross-linking agent. Even if voltage is applied at high temperatures, the breakdown voltage of the cable can be maintained at a high level.

摘要： A composite wire which consists of a number of preferably parallel extending single wire strands bundled to form one solid assembly at least one of which is a bare wire. The composite wire (8) is constructed especially from a bare wire (15) around which a number, for example, five, six or more, single wire strands (9-14) having a thin insulating layer are arranged in the form of a bunch. The assembly is surrounded by a layer of an electrically insulating material, which itself may be surrounded by a layer of a thermoplastic material. This wire is particularly suitable for winding saddle-shaped deflection coils for deflection units for cathode ray tubes.

摘要： Bei einem Verfahren zum Einziehen eines schweren Kabels (1) in einen Kabelkanal (3) werden am Kabel in regelmässigen Abständerr Kabelhalter (5) befestigt, deren Konfiguration dem Querschnitt des Kabelkanals (3) angepasst ist. Mit Hilfe eines Spannseiles (6), weiches an den Kabelhaltern und/oder am Kabel befestigt ist, wird das Kabel (1) in den Kabelkanal (3) eingezogen. Anschliessend wird das Spannseil an beiden Enden unter Zugspannung verankert. Auf diese Weise wird auf das Kabel selbst beim Einziehen keine Zugspannung mehr ausgeübt und das Kabel wird durch die Kabelhalter in einem Abstand von der Innenwand des Kabelkanals gehalten.

摘要： In a plant comprising one or more electric machines constructed with insulated conductors and connected for heavy current via insulated conductors, the magnetic circuit in at least one of these electric machines is connected directly to a high supply voltage of 20 - 800 kV, preferably higher than 36 kV. The insulation of the electric machine is built up of a cable (6) placed in its winding and comprising one or more current-carrying conductors (31) with a number of strands (36) surrounded by outer and inner semiconducting layers (34, 32) and intermediate insulating layers (33). The conductors (31) may be group-wise connected in parallel and semiconducting layers are therefore not required around every conductor in the group. If the conductors (31) are connected in series with each other within the group a part insulation (35) is required which will withstand a few kV, whereas connection of the conductors (31) to every phase requires a strong part insulation (35) which will withstand the phase voltage of the high-voltage supply network.
