No. 16), which contains a fluffy element fixed with a knitting wire to the support. , which is made in the form of a metal cable installed along the length of the supporting surface. The end sections, the cable are untwisted and unbent with the formation of a spatial panicle. The length of each of the braided sections of the cable is 0.35 ÷ 0.45 of the length -L- of the latter. The angle -α- of the mutual deviation of the outermost wire windings of the cable in the vertical plane -P- passing through the central axis O-Ol of the cable is 80 ÷ 110 °.

A disadvantage of the known device is the orientation of the spatial panicle up.

The device provides protection for the pin and support line insulators and adjacent sections of the wire of the overhead power line and prevents electric shock to the birds. It consists of two protective insulating covers having straight or corrugated sections. The end part of the casing is a glass, and the end part of the second casing is a L-shaped segment. The parts are connected to each other by means of a composite sliding latch inserted into the axial hole between the casings and allowing them to move relative to the vertical axis by an angle in the range from 0 ° to 60 °. Slots for the wires of the power line are provided in the end parts of the housings. The number of sections is selected in the range from 1 to 45. The device protects both the suspension insulators and adjacent sections of the overhead power line wire. The device is simple in design, efficient and reliable in operation and universal in application, since it almost completely eliminates damage to lines with insulating suspensions on support and pin insulators due to landing and nesting on them (pollution and overlap of insulation, disconnection of lines, etc. .p.), and at the same time protect the birds themselves from electric shock.

No. 11). The device consists of one or more anti-slip elements and a mounting unit. The antipruritic element (from 1 to 200 pieces) is made in the form of a flat or spatial part made of a dielectric material or of an electrically conductive material with a dielectric coating of its entire surface or with a dielectric coating in separate places of its surface. On the part there are rods (from 2 to 300 pieces) with rounding at the end of a regular geometric shape. In cross section, the rods are in the shape of a circle, ellipse or polygon. The attachment site is made in the form of a clamp and provides fastening of the device to the horizontal or vertical shelf of the traverse of the line support in the entire range of applied angle sections. The device is installed on the traverse of the support of the overhead power line near the place of attachment of the insulator or garland and prevents the bird from landing on the traverse in the zone of its protection.
