Birds use overhead power lines poles as: observation points, hideouts, places to rest or to build nests. Lines with a voltage of 15, 20 and 30 kV, popularly known as MV lines, due to their design pose the greatest threat to them.
The BPS is designed to fill the space between the insulators, making it difficult sitting on the construction elements of MV line poles: crosspieces, connectors as well as at overhead stations. The uninsulated cables on these structures are routed above the head of the pole, which means that birds landing on them may have direct contact with live cables and, at the same time, with earthed metal supporting structures. This creates favorable conditions for the electric current to flow through the bird’s body and, as a result, its death.
