Aircraft Warning Sphere
It is suitable for overhead transmission lines, especially ultra-high voltage
transmission cables and cross-river transmission cables. A striking aviation marking ball should be set on the line to provide aviation markings.
Production Description
Compliance
| - ICAO Annex 14, Volume I, Eighth Edition, dated July 2018 |
● The aviation sign ball is designed as a hollow thin-walled spherical shape, and is made of
● general-purpose lightweight and high-strength polycarbonate material. It has the advantages of
● light weight, high strength, impact resistance, corrosion resistance, and UV protection.
● Super corrosion resistant character, stainless steel bolts and nuts.
● Aluminum alloy cable clamp guarantees good corrosion resistance.
● Various size of cable clamps are available fo 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.
