Customized 600mm composite aircraft warning aerial marker ball Aviation obstruction sphere

Aviation obstruction marking sphere is designed to provide daytime visual warning or nighttime visual warning if comes with reflective tape, for electricity transmission line and overhead wire for aircraft pilots, especially cross river high voltage transmission lines. Lanyu power line marker ball adopts high-grade Fiberglass Reinforced Plastics (FRP), and regular diameter is 400mm,600mm, 800mm

. 

NOTE: OEM（Original Equipment Manufacturer）Acceptable & Customization Available!!!

Have a diameter of about 1/4inches and 5/16 inches. The weight of the power line marker ball is about 17 pounds each. These helps ensure that the weight is not too much for the power lines they are reflecting to bear.

They come in three primary colors, orange, white and red. The three are among the most reflective colors and allow the pilot to stop them even from a far. During installation, they have a gap of about 200-foot between them; that is between one power ball and another. The distance is
put that way also as a way to enhance visibility.
They are installed in the highest wire among all those that they are expected to make visible
They use an alternate color theme to help provide clear visibility without hindrances from the background. In case the color used in one spot is white, the next color will be orange and later red.
They allow wire sag of about 25 feet to help the wires expand and contract in case of a temperature change.

This way, they never are violate the sag requirements of the wires that they are marking.
Have a conductor diameter of 6.5- 5.5 mm
Visibility distance for the power line marker balls is 1200m. From this far, anyone can tell that there is a power line or communication line that they need to evade and know the course to take.
Have a voltage range of about 35KV- 1000KV
There are some drain holes in the sphere which help get rid of water in the power line marker balls. Having water remain in the balls would make them heavy which will overload the wires and even make them fall. Have a cable clamp which is made up of aluminum alloy
