Description

Die Erfindung bezieht sich auf eine Vorrichtung zur Befestigung von Freileitungen an Isolatoren und zeichnet sich im wesentlichen dadurch aus, daß zwei halbkreisform ige, starre, den Isolatorhals umfassende und von entgegengesetzten Seiten in die Isolätorrille eingelegte Bügel vorhanden sind, die in Richtung der Freileitung verlaufende, an den Enden mit Klemmen versehene Verlängerttngen aufweisen. Es sind bereits Befestigungsvorrichtungen für Freileitungen an Isolatoren bekannt, die sich ein oder mehrerer Seildrahtschiingen bedienen, die wohl Zug-,, nicht aber Biegungsbeanspruchungen aufnehmen können: Ferner· hat man .bereits einteilige starre Bügel vorgeschlagen, die in die Rillen des Isolators um denselben herumgelegt sind und vermittels Schellen mit der Freileitung in Verbindung stehen. Auch dieseThe invention relates to a device for fastening overhead lines on insulators and is essentially characterized by the fact that two semicircular shapes ige, rigid, encompassing the insulator neck and from opposite sides into the isolator groove Inlaid brackets are available, which run in the direction of the overhead line have elongated lengths provided with clamps at the ends. There are already fasteners known for overhead lines on insulators, which use one or more rope wire loops, the probably tensile ,, but not able to absorb bending stresses: Furthermore · one already has one-piece proposed rigid stirrups, which are placed around the same in the grooves of the insulator and are connected to the overhead line by means of clamps. These too

ao Bügel sind zur Aufnahme von Biegungsbeanspruchungen schlecht geeignet, da bei einseitigem Zug durch die Freileitung der einteilige Bügel einer Verdrehung unterworfen ist, die ihn und die Freileitung ungünstig be-ao brackets are poorly suited for absorbing bending stresses because they are one-sided Pull through the overhead line, the one-piece bracket is subject to a twist, which adversely affects it and the overhead line.

Claims

claimed. These disadvantages are avoided by the subject matter of the invention, since the two semicircular open brackets run in a straight line at their fastening ends in the direction of the overhead line and are only subjected to tensile loads. In the drawing, the subject of the invention is illustrated in an exemplary embodiment, namely Fig. Ι show the attachment of an overhead line by means of the device according to the invention on an insulator in plan view, Fig. 2 a bracket part in view and Fig. 3 the upper part of a clamp in side view. - The brackets b are hooked into a groove of the insulator α from opposite sides. Their extensions running in the direction of the overhead line e are widened at the ends to form a plate each, which is designated by V in the drawing. An approach b "has recesses in a manner known per se, into which the clamp parts c insert with shoulders c '. The overhead line e is clamped in the clamps by screws d. In the exemplary embodiment, two clamps are provided.

1. Device for fastening overhead lines to insulators, marked by two semicircular, rigid ones that surround the insulator neck and are opposite one another Sides in the insulator groove inlaid brackets, which run in the direction of the overhead line, with at the ends Have clamps provided extensions.

2. Apparatus according to claim 1, characterized in that the direction the overhead line extending extensions by widening their ends as Part of a mounting bracket are formed.
