Factory supply frp fiberglass spherical aviation warning ball
Aircraft warning ball is installed on overhead conductors to alert low flying airplanes and helicopters of the obstacle.They are generally placed near airports and on elevated spans crossing rivers, lakes, fjords, valleys, roads, railways, construction sites and pipelines. Other locations are: near military bases, police stations, hospitals,helicopter routes and other low flying areas. Warning Spheres are attached on the uppermost conductors, shieldwires or on the top of power line towers.
Product Features
1.Designed to be thin Hollow sphere wall with light ,strong intensity and easy installation. weather resistance,hail resistant, bold color is recognized in 360 degree.
Color:Option White,Orange,Red,Orange-white,Red-white and Orange-red.
2 Reasonable structure: Sphere consists of two detachable hemisphere, cable clamp(Die-cast Aluminum, cavity design for skid resistance ) and stainless steel fastener in order to machined and assembled easily.(wire and drain holes be designed ).
3. Armour rod with Al-Mg-Si Alloy: shockproof and protective function.
3.1To prevent suspension position of overhead power line be harmed by shocking, armour rod pass through the sphere be fixed on cable clamp to increases rigidity.
3.2 Anti-looseness: Wires are wrapped up by armour rod to generate grasping force to be protected from arc,friction or other harm, especially for short span wires.
3.3 Easy Installation:One worker can install sphere easily and quickly without any professional tools.

Aircraft warning sphere
Application: It is used on Power Line, providing warning signs.
According to ICAO (International Civil Aviation Organization) Annex 14 , Aircraft Warning Sphere should be used for high-rise transmission lines, especially for super high-voltage power transmission(eg.220KV,500KV), and river-crossing transmission lines to provide the warning marks.
