Conductor suspension mechanism for overhead lines

The invention relates to a conductor suspension mechanism for overhead conductor lines, comprising an insulator having a through hole formed in the region of the tip 5 through which a bracket to which the conductor is attached is passed.

Conventionally, the conductor is attached to the insulator either to the side of its apex neck or to the apex groove of the insulator using a soft bonding wire that is wound in multiple turns around both the conductor and the insulator, with the bonding wire securing the conductor axially non-slip to the insulator. The fastening wire then has to be wrapped by hand around the conductor and the insulator, which is cumbersome and time consuming.

15 Attempts have been made to solve the above-mentioned fastening problem in many different ways, in which case, for example, the insulator structures appearing in the FI patent publications 53 375 and 53 376 and in the publications presented therein as prior art. In these constructions, the use of a bonding wire is intended to replace the insulator with locking parts provided by means of a special design or to be attached to the insulator separately. However, these solutions have proved so difficult to implement that they have not become widespread in use. with the help of the exported handle, the conductor is supported in the apex-30 groove of the insulator. However, even if this provides a secure attachment of the conductor, such a suspension mechanism is only suitable for use with substantially straight conductor portions.

It is therefore an object of the present invention to provide a conductor suspension mechanism which avoids the problems of the previous solutions, i.e. slow manual installation, complicated structure and / or narrow operating range. This is realized by a conductor suspension mechanism according to the invention, which is characterized in that the bracket is semicircular in its central part and is adapted to hang freely with the support of an insulator.

In the following, a more detailed structure of the suspension mechanism according to the invention will be described with reference to the accompanying drawing, in which: Fig. 1 shows the suspension mechanism according to the invention in the conductor direction, and Fig. 2 shows the suspension mechanism in Fig. 1 in the axial direction of the insulator.

Figure 1 shows a suspension mechanism according to the invention, comprising an insulator 1 and fastening means 2 for a conductor 6. In the region of the apex of the insulator 1, its so-called

A through hole 3 has been formed in the neck portion 15, which is extended at its ends, which is fitted parallel to the conductor line when the insulator is installed. A suspension bracket 4 of roundish material is passed through this hole 3, to which the conductor 6 is attached.

As can be seen in Figure 2, the suspension bracket is preferably semicircular in its central position and straight at the end, the conductor 6 being attached to these straight end portions of the bracket. A prestressed threaded tie 5 can be used to fasten the conductor, whereby the fastening 25 is very fast to perform.

Of course, the use of a conventional dressing is also possible. When using insulated open wires, the ends of the suspension bracket 4 can also be somewhat extended, which gives the suspension bracket the characteristics of the arc damage prevention device 30.

The conductor suspension mechanism according to the invention is very quick and easy to install and is suitable for use both on straight sections of the conductor line and also at corners. The suspension mechanism according to the invention achieves a good axial attachment of the conductor and also reduces the conductive damage of the conductor vibrations.
