TROLLEY-TYPE DEVICE OF POWER TRANSMISSION LINE PROTECTION FROM BIRDS Russian patent published in 2014 - IPC H02G7/00 A01M29/32 

FIELD: electricity.

SUBSTANCE: device includes plate 1 out of flexible dielectric material in the cross form with four perpendicular shortened beams 2, 3, 4, symmetric against an axis passing through two opposite beams 3, 4, one of which is shorter and thinner than the other. Plate 1 features at least ten orifices 5, 6, four of which are made in beam 3, located in two pairs adjoining its sides, and six other orifices are adjoining protruding angles of other beams 2, 4. In addition, device includes dielectric fixation elements 10 for plate 1, passing through each pair of orifices 5, 6 opposing each other when the plate 1 is folded by the said symmetry axis.

EFFECT: device range for protection of birds against electric shock extended with a trolley-type device of unified design for installation on suspended devices of various designs, with reliable attachment not requiring special fixtures on bearing elements, preventing slipping and rotation during operation by wind or other dynamic loads, easy to dismount and simple to produce and install.
