Powerline Using Aircraft Warning Sphere / Aerial Marker Balls ICAO
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.
1.Diameter length of Aircraft Warning Sphere: Φ600mm
2.Character of fiber glass:
-Resistance temperature : 40℃～90℃
3.Fastener: Aluminum material, M10 by 35, M10 by 40
4.Weight of Sphere: 6.3Kg
5.Sphere Color: Orange , Red or White
6.Material: Fiber glass reinforced polyester resin
Scope of Application
1. high-rise transmission lines, eg.110KV, 220KV, 500KV,.
3.river-crossing transmission lines
1.At the mount point on the alerting ball, wrap cable protecting
bars round cables for 1000-1200mm long, with two ends of protecting
bars extending 200-300mm beyond the surface of the ball.
2.Fix the plastic wires which are mounted on lower hemisphere of
the ball onto the cables and twist them.
3.Combine the lower hemisphere with the upper hemisphere according
to module codes. Turn the hemisphere during the assembly and make
sure two hemispheres are joined into position .
4.Insert stainless steel bolt(M12*35) and then put flat washers and
spring washers around each bolt. Tighten each nut at last.
