Aviation obstruction marking spheres are designed to make electricity transmission lines, especially cross river high voltage transmission lines visible for aircraft pilots.



Colours of aircraft warning spheres are important issue. In installations of warning spheres, white and red, or white and orange markers should be chosen according to the background. There should be contrast between aircraft warning spheres and the background environment in order to be able to make aerial marker balls visible.



 warning spheres are especially designed to warn approaching air vehicles of power lines hung between supporting towers.



The spheres are used for daytime marking of cables at high-rise transimission lines,  transmission cables and river-crossing transmission lines.



 warning spheres are constructed from two hemispheres that are connected to each other and to the elevated power line by stainless steel fixing brackets.



Wetra Warning Spheres / Marking Spheres / Aircraft Obstruction Spheres



Wetra warning spheres are daylight beaconning installed on the high voltage lines and stays of pylons.
Wetra warning spheres are extremely light and very resistant to the weather, the warning sphere is available in red, white and orange.
Wetra warning spheres can be adapted on every diameter of line




   Advantages of Wetra Marking Spheres



Resins used for Wetra warning spheres are styrenic polymers which enable to have
Weather resistant
Physical property retention after UV exposure
Colour stability
Practical toughness and rigidity
Resistant to common household cleaners
Recyclable
Easier installation thanks to its mounting system (mounting adapted to the cable)




The resins, that we used, are weatherproof, high-impact, styrenic polymers specifically designed for use in outdoor applications.



Resistant to sunlight, the resins maintain significant physical properties after weathering.

Aerial Marker Balls

Sales： hebeicp@qq.com   Aerial Marker Balls help save lives and protect expensive infrastructure by making power lines and guy wires more visible to low-flying planes and helicopters. Marker Balls are typically used in airport and heliport approach areas and where power lines span long distances crossing canyons, lakes and rivers. The Model JX is available in four diameters: 9", 12", 20" or 24". INSTALLATION This Marker installs easily on any wire 1/8" - 1" (custom wire sizes are available) through the use of two UV resistant neoprene strip bushings installed on the wire to match the diameter of the openings (boss) in the Marker. The Marker is then securely bolted around the wire, clamping down on the bushings. COLOR OPTIONS Our standard color is "International Danger Orange;" (U.S. Engineer's Spec. 595-121197 or British STD. 381C-1964-No. 557) however, yellow and white are available as an option. In some cases, these color...
