A device for protection of birds from electric shock on power lines comprises a casing of insulating material, installed on a wire on both sides of the insulator. The casing is made in the form of an elastic tape 1 made of an insulating material, for example rubber, a zigzag bent lengthwise longitudinal axis and provided with through holes 2 for the passage of wire 3, and at the ends of the tape 1 on the wire 3 there are clips 4 that prevent the tape from spreading 1 along the length of the wire 3. The clips can be made of any known construction, for example, in the form of a wire tie or a clamp.

tapes, rubber mats, carpets, etc.

To install the tape 1 on the already existing transmission lines on the tape 1, slots 5 are made from holes 2 to the edge of the tape 1, with adjacent adjacent slots 5 directed to different sides from the longitudinal axis of the tape, which increases the reliability of installing the tape on wire 3

Tape 1 can be installed on a wire with a bend both in a vertical plane and in a horizontal one (FIG. 3).

The casing can be made of several successively installed segments of curved ribbons unrelated to each other and separated by clips 4 (Fig „4). In this case, the individual tapes can rotate around the wire 3 independently of each other. This expands the capabilities of the device, since it prevents birds from landing on wire 3 at isolator 6. Such an embodiment of the casing allows the use of short trimming of tapes without connecting them together.

The casing can also be made from one single piece of tape (figure 5 and 6). In this case, one of the turns of the bend tape curls around the insulator 6 from the side (FIG. 6) or from above (FIG. 5), protecting the insulator 6 from the corresponding side.

The casing can be made in the form of two elastic zigzag bent tapes 7 and 8 aligned along the length, the bending planes of which are shifted around the axis of the wire 3 by 90 °, with the turns of one tape placed between the turns of the other tape (Fig.7 and 9).

When the casing is made of three aligned tapes, the bending planes of the tapes are offset relative to each other by an angle of 60; when the casing is made of four tapes, the bending planes of the tapes are shifted by an angle of 45, etc.

The casing can be made of a curved tape, the bends 9 of each turn of which are made flat (Fig "8 and 9). In this case, the surface of the casing takes on a flat box-like shape, and the gaps between the coils are sealed by the coils of the coils moving in plane.

The manufacture, installation and operation of the proposed device are performed as follows.

In a section of tape 1 of insulating material, for example rubber, 5–10 cm wide along the length along the longitudinal axis, holes 2 are made to pass the wire 3. The distance between the holes 2 is selected in accordance with the width of the casing.

When the device is placed simultaneously with the installation of the transmission line, the casing is installed by passing the wire through the openings 2, followed by the installation of the clamps 4 at the ends of the leg 1, after preloading it with compression of the tape turns with each other.

When the device is placed on an already operating transmission line, on the tape 1, slots 5 are made from holes 2 to the ribbon edge. In this case, the housing is installed by inserting wire 3 through slots 5 into holes 2 successively along each of the turns. In order to more reliably place the tape on the wire 1, the slits 5 from the adjacent holes 2 are made in different directions from the longitudinal axis of the tape. This embodiment of the tape prevents the casing of the wire 3 from slipping through the slots 5. After alternately stringing all the turns of the tape onto the wire 3, it is moved along the wire by displacing the turns to each other, ensuring a tight fit, then clamps A at the ends of the tape 1 ruled this position of the tape. Since the tape is made of an elastic material, the turns of the zigzag bent tape are elastically pressed against each other, forming an integral protective structure.

According to the embodiment, the casing on both sides of the insulator 6 can be made of a single tape. In this case, the tape bends around one of the turns the insulator 6 from the top (Fig „5) or on the side (fig

The implementation of the casing of the combined two or more tapes is as follows,

Through the slots 5 on the wire 3 string the ends of both tapes 7 and 8, the tapes are shifted relative to each other with two tapes, 60 times with three

90 with two tapes, 60 tapes and tod. After that, alternately, each of the tapes begins to be strung through the slots 5 onto the wire 3. After the strips are completely installed, the resulting daisy is shifted and fixed at the ends with the clips 4.

The casing created in this way has a box-shaped form that is closed on all sides. At the same time, the insulator 6 can also be closed by tape windings on the top and side of the crossbar (not shown) ().

Similarly, the installation of the tape is performed, the bends of the 9 turns of which have a flat shape. At the same time, over the insulator 6, the bends 9 can be made somewhat wider than along the length of the tape 1. Such a tape can be obtained from a conventional tape by passing it through rolls of a corresponding shape.

The bird, being on the traverse (not shown), touches the casing with its beak, what it does when it is cleaned, or steps over from the traverse to the casing of wire 3 or part of the casing above the insulator 6,

At the same time, it is not damaged by electric current, since it is 5 protected from current-carrying parts due to the presence of an insulating casing for a part of the length of the wire at the insulator, as well as due to the protection by the casing and insulator on the cable side.

When flapping wings and touching the wires 3 near the insulator 6, the damage to the bird also does not occur due to the presence of the casing.

The free installation of the casing with the possibility of its rotation around the wire prevents the birds from landing on the wire 3 near the isolator 6, since when the bird lands the casing turns around the wire, the bird loses its balance and flies away. Thus, the device has, in addition to protection, a scaring effect on birds.

Due to the tight fit of the casing, the latter is reliably located on the wire and the insulator, the probability of loosening and falling is practically excluded. But even disrupting the casing from the wire cannot cause the high-voltage disconnection of the line, since the casing is made of insulating material. The gaps between the coils are small so that the bird can get into them with a wing, claw or beak and touch the grounded part of the support.

example of conveyor belts, rubber carpets, etc. to a certain extent solves the problem of utilization of this type of materials, which reduces environmental pollution.

The device is not afraid of mechanical shocks, has high frost resistance, resistance to solar radiation, corrosion resistance. The device can be made from a series of tapes of different lengths, which allows it to be installed on the wire to any desired length.

The feasibility of the device is to reduce the cost of protecting the wire with an insulating jacket. The device is simple in construction. The cost of equipping transmission towers mainly includes only transportation costs for delivery to the installation site and installation costs.

In the proposed device, it is possible to select the desired width of the tape, significantly increasing the distance from the wire, due to the availability of the material. With such a protective device design, the slits in the wire direction do not significantly affect the electric strength of the protective device and practically any rejected tape with punctures and cracks can be used, although the same rejected tape is inoperable when used in a tubular casing, longitudinally covering wire.

The ease of installation, low cost, availability of raw materials, as well as reliability and durability in operation allow the proposed device to be widely used to protect birds from damage.
