These are the first to be installed in the transmission grid of the island of Gran Canaria.
The marking of the electricity lines with bird-flight diverter increases their visibility and significantly reduces the number of birds colliding with them. These devices are brightly coloured polypropylene (PVC) spirals that wrap around the grounding cable and allow the devices to be seen over long distances.
The electricity line that birds collide into is the grounding cable, which is used as the lightning arrestor and has a smaller diameter than the conductor cables and is therefore less visible to birds.
The area where bird-flight diverters were installed has two marked characteristics that increase the risk of bird collisions: the existence of three irrigation ponds that birds use as a drinking source and the strong winds in the area that blow perpendicular to the electricity line. This was confirmed during research studies on Red Eléctrica lines performed ??in five stages after the acquisition of the transmission assets.
