Sphera is rethinking aviation safety. Our aerial marker balls are designed for efficiency and sustainability, drastically reducing installation time and, in turn, CO₂ emissions.
NEW: Installation by drone is now possible too!
Our aerial marker balls are designed for fast, easy installation. With preassembled half-shells and a quick-lock mechanism, they reduce installation time by 70% compared with competing products, delivering significant cost savings. Sphera aerial marker balls are the only ones on the market that can be installed using either a helicopter or a robotic drone.
Our marker balls are ideal not only for high-voltage power lines but also for a wide range of other applications, including mountain cableways, utility lines and navigation pylons.
Catering to diverse requirements, our marker balls come in two sizes (300mm and 600mm) and can be ordered in standard colors or custom shades for bulk orders. Their design accommodates various cable thicknesses, ensuring suitability for different applications.
Our aerial marker balls are made predominantly from recycled materials, including fully recyclable aluminum clamping jaws. We are committed to sustainable practices, from production through to our innovative "Cradle-to-cradle" recycling program.
Thanks to our patented solution, the Sphera Marker is officially the fastest-to-install aerial marker ball on the market. This saves you time and money while also reducing environmental impact through shorter helicopter operations or drone-based installation, as well as exceptionally durable material.
With innovative robotic and drone solutions, Sphera is setting new standards for installing marker balls on overhead power lines. Advanced installation technology using the FulcrumAir LineFlySystem enables fast, precise and safe installation, even in hard-to-reach areas. This reduces installation times and minimizes risks, while providing grid operators with an efficient, forward-looking solution for marking overhead power lines.
Made from recycled materials, fully recyclable, supporting environmental conservation
Back-to-the-Roots' initiative for sustainable reuse of marker balls
Utilizing renewable energy and heat recovery for reduced carbon footprint
Shorter installation times and therefore lower CO₂ emissions when installing by helicopter or drone
Sphera aerial marker balls are manufactured by MS Design from high-quality, solid-colour ASA material. This ensures strength, durability and resistance to changing and harsh weather conditions. Our commitment to sustainability means that 97% of our aerial marker balls are made from recycled ASA.
More on sustainability
