FIELD: electric power engineering.
SUBSTANCE: invention relates to power engineering, in particular to anti-ward devices, designed to protect the chains of insulators of overhead power lines with voltage of 6–1150 kV, as well as to protect birds from the negative impact of the overhead power lines themselves. Device consists of an anti-priming element and a mount. Anti-junction element is in the form of thin-walled shell 1 with vertex at point 2 and base 3 in the form of an ellipse, or a circle, or a polygon, or a combination of the above-named figures, curve 4 formed by rotation, representing a horizontal or inclined segment or a part of a circle or a combination of the above-mentioned figures at apex 2, passing into a part of the hyperbola, or parabolas, or a straight line or combination of the above elements around base 3. Shell 1 is made of a polymeric material and may consist of several parts, fastened with the help of latches 5.
EFFECT: device eliminates the contact of birds with current-carrying elements and bird nesting on overhead power lines.
