Installation and distribution of aviation obstruction lights:
1. The setting of obstacles should mark the higher point and the edge of the obstacle (ie, the apparent height and width).
2. If the top of the object is more than 45 meters above the ground around it, an obstruction light must be installed in the middle layer, and the distance between the middle layer must be different.
more than 45 meters and equal as much as possible (super-high buildings above 100 meters in the city, especially considering the installation of obstruction lights in the middle). When installing intermediate-level obstruction lights on buildings located near cities and residential areas, consideration should be given to avoid making residents feel uncomfortable. It is generally required that only scattered light can be seen from the ground.
3. Obstruction lights installed in large-scale buildings should be able to see the outline of the object from all aspects. The horizontal direction can also refer to the installation of obstruction lights at an interval of about 45 meters.
4. For 105-meter-long ultra-high objects, facilities or cable towers, roof towers, etc., a medium-intensity A-type obstruction light should be installed at the top of the object, with white flashing, and a red medium-intensity B-type obstruction should be set on the lower part of it. light.
5. Ultra-high objects higher than 150 meters (such as radio and television towers, long-span cable-stayed bridges, etc.) should be equipped with high-intensity A-type obstruction lights at the top, and medium and high-intensity obstruction lights should be used in conjunction.
6. Ultra-high-voltage transmission line towers should be equipped with high-intensity B-type obstruction lights, and the three-layer synchronous flashing should be provided. The location is the top of the tower, the lower point of the cable sag, and the middle of the two, and it needs to be located outside the tower along the cable routing direction.
7. For chimneys or other buildings of similar nature, the top obstruction lights must be located between 1.5-3 meters from the top. Taking into account the pollution of the chimney to the lamps, the obstruction lights can be installed 4-6 meters below the chimney mouth (detailed See excerpts from national standards).
8. No matter what kind of obstruction light, the number and arrangement of obstruction lights at different heights should be able to see the outline of the object or group of objects from all directions, and the synchronized flashing of the obstruction lights should be considered to achieve an obvious warning effect. But in fact, many times, the use of obstruction lights is not a single type of use, but three types of obstruction lights are used in combination according to the actual obstacle height. Different heights use different coordination, sometimes it is necessary to use three types of obstruction lights of low intensity, medium intensity, and high intensity aviation obstruction lights to indicate the existence of obstacles.
The above is the distribution requirements for aviation obstruction lights in the document. Based on this, we produce the products required by each customer and place of use. If you have any questions or suggestions, please contact us.
