Description
Längswasserdichtes Kabel. Longitudinally watertight cable.
Die Anmeldung bezieht sich auf elektrische Kabel mit aus einer Vielzahl von Adern bestehenden Seele, die zum Schutz gegen das radiale Eindringen von Feuchtigkeit mit einem wasserdichten Mantel umgeben ist. Die Kabel sind ausserdem mit einem Werkstoff gefüllt, der verhindern soll, dass sich Wasser längs der Kabelseele ausbreitet, falls der Kabelmantel beschädigt werden sollte.The application relates to electrical cables with a variety of cores existing core, which protect against the radial penetration of moisture is surrounded by a waterproof coat. The cables are also made of one material filled to prevent water from spreading along the cable core, if the cable jacket should be damaged.
Es sind bereits Kabel mit kunststoffisolierten Leitern bekannt, die entlang ihrer längserstreckung diskontinuierlich mit Wassersperren versehen sind. Diese Wassersperren müssen mit verhältnismässig kurzem Abstand angeordnet sein, damit eventuell eindringendes Wasser sich nur über eine kurze Kabel strecke ausbreiten kann; durch die kurzen Abstände haben sie jedoch eine nachteilige Wirkung auf die elektrischen Ubertragungseigenschaften des Kabels.There are already cables with plastic-insulated conductors known that are discontinuously provided with water barriers along their length. These water barriers must be arranged with a relatively short distance, so that any water that may penetrate can only spread over a short stretch of cable can; however, due to the short distances, they have an adverse effect on the electrical transmission properties of the cable.
Ein anderer bekannter längswasserdichter Kabelaufbau enthält mit geschäumtem Kunststoff isolierte Adern und einen wasserdichten Kabelmantel, wobei die Zwischenräume im Kabel mit einem wasserundurchlässigen Werkstoff gefüllt sind. Die nachteilige Wirkung der geschäumten Xunststoffisolation auf die tJbertragungseigenschaften wird bei diesem Aufbau durch die Wirkung des wasserundurchlässigen Werkstoffes ausgeglichen.Another known longitudinally watertight cable structure contains foamed Plastic insulated wires and a waterproof cable jacket, with the gaps in the cable are filled with a water-impermeable material. The disadvantageous one Effect of the foamed plastic insulation on the transmission properties in this structure balanced by the effect of the water-impermeable material.
Es ist Aufgabe der Anmeldung einen anderen Aufbau für ein elektrisches ebenfalls längswasserdichtes Kabel anzugeben, dessen elektrischen Werte nicht durch die verwendeten Werkstoffe beeinträchtigt werden.It is the task of registering a different structure for an electrical one also specify a longitudinally watertight cable whose electrical values do not pass through the materials used are impaired.
Erfindungsgemäss besteht die Isolation der Adern aus einer um die elektrischen Leiter gewickelten Eunststoff/Papier-Verbundfolie, bei der die Papierschicht auf dem Leiter liegt und die Uberlappung verschlossen ist, und die Zwischenräume zwischen den Adern und Mantel sind mit einer nichthärtenden Paste gefüllt.According to the invention, the insulation of the wires consists of one around the electrical conductor wrapped plastic / paper composite film, in which the paper layer lies on the ladder and the overlap is closed, and the spaces in between between the veins and sheath are filled with a non-hardening paste.
Nach einem weiteren Merkmal der Erfindung sind die Leiter doppelt mit Verbundfolie umwickelt. Die Uberlappung der Verbundfolie soll entweder unter Wärmeeinwirkung verschweisst oder mittels eines Klebstoffes verschlossen sein. Der Kunststoff der Verbundfolie besteht aus Polyäthylen; die nichthärtende Paste ist eine petroleumhaltige Paste.According to a further feature of the invention, the conductors are double wrapped in composite film. The overlap of the composite film should either be under Welded under the influence of heat or sealed by means of an adhesive. Of the The plastic of the composite film consists of polyethylene; is the non-hardening paste a petroleum paste.
Ein gemäss der Erfindung aufgebautes Kabel wird nachstehend anhand der Figuren 1 und 2 erläutert. Es zeigen Fig. 1 a eine doppelt mit Verbundfolie umwickelte Ader Fig. 1 b einen vergrösserten Ausschnitt der Verbundfolie aus Big. 1 a und Fig. 2 ein elektrisches Kabel gemäss der Erfindung.A cable constructed in accordance with the invention is illustrated below with reference to of Figures 1 and 2 explained. FIG. 1 a shows a double laminated film wrapped wire Fig. 1b an enlarged section of the composite film from Big. 1 a and 2 an electrical cable according to the invention.
In Fig. 1 a ist ein doppelt mit Eunststoff/Papier-Verbundfolie 2 umwickelter Leiter 1 erkennbar, auf dem die Papierschicht 4 innen und die Kunststoffschicht 3 aussen liegt.In Fig. 1 a is a double wrapped with plastic / paper composite film 2 is Head 1 can be seen on which the paper layer 4 inside and the plastic layer 3 is outside.
Ein Ausschnitt der Verbundfolie ist in Fig. 1 b vergrössert herausgezeichnet.A section of the composite film is shown enlarged in FIG. 1b.
Fig. 2 zeigt die mit Verbundfolie isolierten Adern 7, die in bekannter Weise zur Kabelseele geformt und von einem wasserdichten Kabelmantelyumgeben sind. Die Zwischenräume 8 zwischen den Adern 7 und zwischen den Adern 7 und dem Kabelmantel 6 sind mit einer nichthärtenden Paste gefüllt.Fig. 2 shows the insulated with composite film wires 7, which in known Formed into a cable core and surrounded by a waterproof cable sheath. The spaces 8 between the wires 7 and between the wires 7 and the cable jacket 6th are filled with a non-hardening paste.
Bei einem abgeänderten Kabelaufbau kann die Eunststoff/Papier-Verbundfolie auch nur einfach mit Uberlappung um den Leiter gewickelt sein. Die Überlappung der Verbundfolie kann entweder durch Anwendung von Wärme oder durch einen Kleber verschlossen sein. Der Kunststoff der Verbundfolie soll aus Polyäthylen oder einem ähnlichen Werkstoff bestehen, während für die nichthärtende Paste eine petroleumhaltige Paste oder ein ähnlicher Werkstoff geeignet ist.With a modified cable structure, the plastic / paper composite film also simply be wrapped around the conductor with an overlap. The overlap of the Composite film can be closed either by applying heat or by means of an adhesive be. The plastic of the composite film should be made of polyethylene or something similar Material exist, while for the non-hardening paste a petroleum-containing paste or a similar material is suitable.
Die Erfindung ermöglicht es, papierisolierte elektrische Kabel unter Beibehaltung guter elektrischer Eigenschaften längswasserdicht herzustellen, die als Erdkabel geeignet sind.The invention enables paper-insulated electrical cables under Maintaining good electrical properties to produce longitudinally watertight are suitable as underground cables.
