Powerline Aviation Marker Ball for overhead transmission line
Aviation obstruction marking sphere is designed to provide the 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. RedDot OMARK power line marker ball is made of high-grade Fiberglass Reinforced Plastics(FRP), the diameter of 600mm and 800mm are available to meet different customers’ needs.
A marking sphere should be of one color such as aviation orange, white and red. Generally, the marking spheres are placed on the highest line. Where there is more than one line at the highest level, white and red, or white and orange spheres should be displayed alternately. This alternating color scheme provides the most conspicuity against all background.

• Various size of cable clamps are available to fit for customers’ cable conductor
• Drain holes structure can prevent accumulated rain water inside the spheres
• Stacking compatible design, save storage space and freight charge
• Optional Preformed Armor Rods provide better protection against vibration and abrasion
• Optional Reflective tape is more durable and economical solution for night visibility
• Both sphere diameters of 600mm and 800mm are available
• Power transmission Line
• Overhead line
• Guyed wire for self-supported guyed tower
• ICAO Annex 14, 4th Edition, July 2004
• FAA AC 70/7460-1K, obstruction Marking and Lighting
For Example, OMARK600O13.1AR means a 600mm diameter warning sphere, orange color, with preformed armor rods, suitable for diameter 13.1mm cable conductor.
Note :
For making sure the spheres can fit for cable conductor well, customers need to provide conductor diameter, material and code.
