The name of these devices that look like a pokeball “warning bulbs”It is usually seen near airports because it is placed on electrical wires to warn vehicles such as low-flying planes and helicopters.

They are also used in electrical wires that run across rivers, lakes, fjords, valleys, roads, railways, construction sites and pipelines. Moreover your military bases and near police stations.

Warning spheres, consisting of two hemispheres, are UV and ozone resistant materials.

It is connected to the air conductive guide with two bolt clamps. Thanks to the special installation mechanism by a single technician can be easily placed on the guide. The design of the clamping structure prevents the deformation caused by the tightening of the bolts.

It is made of polyethylene. jaws made of aluminum Since it is made and contains grooved channels, situations like slipping never occur. Drainage holes in the bulb prevent the accumulation of rain in the bulb.

Color selection is very important in the warning spheres, making power lines easy to see.

In the area where the orb is placed to the color of the background attention should be paid. In general, colors such as white, red, orange are preferred. A contrast must be maintained between the background and the warning spheres. Sometimes the colors can be changed according to the seasons.

The place where they are installed is the lightning protection ground of the tower. hang rope. The diameter of the spheres is usually 600 mm, the distance between them is 30 m. The distance increases with the size of the diameter.

Since it is very difficult to see power lines, especially in foggy and cloudy weather, helicopter accidents have been prevented thanks to these red and white balls. But in the world generally power line: LED warning lights available. They are much more visible than spheres, especially at night.
