Aircraft Warning Device (Sphere) - visual marking of overhead power lines crossing fjords, valleys and rivers or generally where there is a need to make power lines visible to aircraft and helicopters

 Aircraft Warning Device (Sphere) -  visual marking of overhead power lines crossing fjords, valleys and rivers or generally where there is a need to make power lines visible to aircraft and helicopters.


The Warning Spheres marker ball are attached on the uppermost conductors, shieldwires or on the top of power line towers.

The warning device consist of two hemispheres attached to the overhead conductor by two bolted clamps. The key element of the Warning Sphere is UV and ozone resistant material polyethylene.


The special installation mechanism allows a single linesman to easily install the Warning Sphere. Moreover a properly designed clamp structure avoids deformation of the sphere material due to tightening of the bolts. Due to the application of a stainless steel safety plate, clamp loosing is impossible. The high rigidity of the spheres prevents acoustic noises including rattle between the two hemispheres and vibration fatigue problems, for the whole life time of the overhead conductor on which they are installed. The Aviation Warning Spheres fulfill the requirements of the International Civil Aviation Organization (ICAO) guidelines for marking obstacles.


Warning spheres must be visible in daylight at a distance of minimum 1500 meter from all inflight angles. Specific requirements to dimensions and distance between the warning spheres apply. All warning spheres must have a reflective surface.

Installation & Commissioning of Medium-Intensity Obstruction Lighting System for Transmission Lines Medium-Intensity Type A obstruction lights are white flashing lights used for marking tall structures like transmission towers, especially in areas near flight paths. They emit a light intensity of 2000–20000 candela (cd) and are designed for visibility during day and night.

ICAO Compliance: LED Heliport Approach Path Indicators (CHAPI Light) & LED Airport Precision Approach Path Indicators ( PAPI Light) ICAO (International Civil Aviation Organization) sets essential safety standards for aviation lighting, including for Heliport Approach Path Indicators (Green/Red/White CHAPI Lights) and Precision Approach Path Indicators (Red/White PAPI Lights). These systems help pilots maintain the correct glide path during approach and landing, improving safety and reducing risk.

LED PAPI & CHAPI Lights, designed for helipads and airports, illuminate pathways for pilots, enhancing visibility and ensuring precision,ensure safe landings with advanced heliport lighting!
