Putting a small windmill on a telephone pole is installed by the power department and has nothing to do with testing wind speed, wind direction and beauty. Used to prevent birds from nesting on medium voltage telephone poles equipped with transformers. At present, many birds often use wire to build nests. The iron wire falls on the transformer, which is easy to cause a short circuit accident. The small mirror on the bird repeller will reflect light when it rotates with the wind, which can drive the birds away.
It can play a certain role in repelling birds and preventing bird stings, but it is not ideal in many cases. Many birds may be afraid of bird repellers at first, but gradually they become immune and build nests next to them. Therefore, the power company installed small windmills on the tower where it is suitable for nesting, and even attached reflectors. As long as the wind blows, the car will move and flash, and the birds will stay away from here, effectively reducing the route travel.
