The Alrouf GS-AWS aircraft warning sphere is an unlighted aerial marker ball used to improve the visibility of overhead transmission lines and cable crossings. Its colored spherical body provides a visual reference that helps pilots identify wires against the surrounding landscape.
The GS-AWS uses high-strength glass fiber or FRP construction, a reflective surface coating and an aluminium-alloy clamp assembly. Published specifications include red, white and orange color options, an ambient-temperature range of −55°C to +85°C, and a wind-loading rating of 80 m/s.

The GS-AWS can be evaluated for:
Final selection should consider the required marker diameter, color arrangement, spacing, wire compatibility and line-loading assessment.
For an explanation of how these markers are used, read our guide to aerial marker balls for power lines.
Marker requirements depend on the installation location, applicable aviation guidance and the project specification.
If your project references FAA obstruction-marking guidance, ICAO Annex 14 or local aviation requirements, provide the relevant document and edition when requesting a quotation. The product configuration and complete installation arrangement should be checked against those requirements.
Ask Alrouf for the available technical documents and evidence required for your product submission. Product color, size or appearance alone does not establish compliance with every marking requirement.
The GS-AWS uses a clamp assembly to attach the sphere to the specified wire. Confirm clamp compatibility before ordering.
Installation should be performed by qualified teams following the utility owner’s procedures and the manufacturer’s instructions. The line assessment should account for the marker’s weight, wind loading, mounting arrangement and effect on the wire.
Periodic inspections should check:
Follow the manufacturer’s specified inspection and tightening instructions.
No. The GS-AWS described here is an unlighted visual marker. Its reflective coating does not generate light.
Where nighttime obstruction lighting is required, evaluate suitable aircraft warning lighting solutions against the project specification.
These terms commonly describe the same type of spherical overhead-wire marker. “Aviation ball” and “obstruction ball” are also used. Confirm the model and specifications when comparing products.
The published GS-AWS color options are red, white and orange. The required color and arrangement should be selected according to the applicable project requirements.
Compatibility depends on the supplied clamp configuration. Provide the wire type and dimensions so the correct mounting arrangement can be confirmed before ordering.
Spacing should be established through the project’s marking design. It depends on the location, span characteristics, marker size and applicable aviation requirements.
The model can be evaluated against the project’s temperature, wind-loading, visibility and mounting requirements. Confirm the published ratings and requested supporting documents before approval.
Send Alrouf your project location, required quantity, sphere colors, wire details, proposed layout and marking specification.
