Powerline Using Aircraft Warning Sphere / Aerial Marker Balls ICAO Standard

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.
