Description

Elektrische Kabel und Leitungen mit einer Isolierung aus Kunststoffen In der Kabel- und Leitungstechnik werden in zunehmendem Maße Kunststoffe, insbesondere Polyvinylchlorid, als Isolierungs- und Ummantelungswerkstoffe auch für Betriebsspannungen über 1 kV eingesetzt. Es war bisher im allgemeinen nicht erforderlich, bei diesen mit Kunststoff, insbesondere Polyvinylchlorid, isoliertenKabeln undLeitungen eine besondere Endenzubereitung vorzunehmen. Es wurde jedoch festgestellt, daß die Betriebssicherheit überall dort, wo, mit großen Schmutzablagerungen und mit Feuchtigkeitseinwirkungen an den Enden gerechnet werden muß, nicht mehr vorhanden ist. Da die auftretenden Oberflächenentladungen sehr schnell die Kunststoffisolierung, insbesondere eine solche auf Polyvinylchloridbasis, zerstören.Electric cables and wires with insulation made of plastics Plastics, in particular, are increasingly being used in cable and line technology Polyvinyl chloride, as insulation and sheathing materials, also for operating voltages used over 1 kV. So far it has generally not been necessary with these with plastic, in particular polyvinyl chloride, insulated cables and lines make special end preparation. However, it was found that the operational safety wherever, with large deposits of dirt and with the effects of moisture must be expected at the ends, is no longer available. Since the occurring Surface discharges very quickly the plastic insulation, especially one those based on polyvinyl chloride, destroy.

Dieser Nachteil wird gemäß der Erfindung in einfachster Weise dadurch beseitigt, daß der Mantel bzw. die Isolierung aus Kunststoff, insbesondere an den Enden der Kabel und Leitungen, mit einem dünnen. Überzug aus einem kriechstromfesten Kunstharz, z. B. auf der Basis von Polyaryl-Äthylen-Oxyd bzw. Äthoxylinharzen od. dgl., versehen ist. Ein derartiger Überzug hat eine besonders hohe Widerstandsfähigkeit gegen Oberflächenentladungen, so daß eine gefährliche Beeinflussung der Betriebssicherheit, insbesondere an den Enden der Kabel und Leitungen, in einfacher Weise vermieden wird.According to the invention, this disadvantage is thereby achieved in the simplest manner eliminates that the jacket or the insulation made of plastic, especially on the Ends the cables and wires, with a thin one. Coating made of a tracking current resistant Synthetic resin, e.g. B. based on polyaryl-ethylene oxide or ethoxylin resins od. Like., is provided. Such a coating has a particularly high resistance against surface discharges, so that a dangerous influence on the operational safety, in particular at the ends of the cables and lines, avoided in a simple manner will.

Es ist bekannt, Äthoxylinharz in der Hochspannungstechnik zu verwenden. Man hat z. B. Hochspannungsporzellan durch Körper aus Äthoxylingießharzen ersetzt. Äthoxylingießharze haben den Vorteil, daß sie hoch stromfest sind und mit anderen Werkstoffen verarbeitet werden können. So hat man bereits Verbundkörper, die zum Teil aus Metall und zum Teil aus Äthoxylinharz bestehen, hergestellt.It is known to use ethoxylin resin in high voltage engineering. One has z. B. High-voltage porcelain replaced by bodies made of Äthoxylinießharzen. Ethoxylin casting resins have the advantage that they are highly current resistant and with others Materials can be processed. So you already have composite bodies that are used for Partly made of metal and partly made of ethoxylin resin.
