The CM-600 Cable Marking Spheres are specialized aircraft warning devices designed to enhance the visibility of high-rise transmission lines, helping to prevent aerial collisions by alerting pilots to potential hazards. These spheres are especially critical in areas where transmission cables cross large open spaces, such as rivers, or in the case of extra-high voltage (EHV) power lines that are suspended at significant heights.
Developed in compliance with ICAO Annex 14 standards, the CM-600 marking spheres serve as a highly visible alert system for both manned and unmanned aircraft, supporting safe aviation navigation around tall electrical infrastructure. Their vivid, colored finish ensures high contrast against the sky, making them easily noticeable from a distance during daylight hours.
Engineered for long-term outdoor use, the CM-600 spheres feature a weatherproof glazed coating that withstands harsh environmental conditions, including extreme temperatures ranging from -40°C to +90°C. The materials used are highly corrosion resistant, ensuring reliable performance in marine, industrial, and remote locations.
Mounting is made secure and straightforward through a screw-on installation design. The spheres are constructed using fiber-reinforced glass (FRG) materials, offering excellent mechanical properties. These include a tensile strength greater than 128 MPa, flexural strength exceeding 230 MPa, and a Barcol hardness rating above 44, making the CM-600 spheres robust and impact-resistant even in severe weather or high-wind environments.
In summary, the CM-600 Cable Marking Spheres offer a durable, ICAO-compliant solution for marking overhead power lines and transmission cables, providing vital protection for low-flying aircraft while delivering dependable, all-weather performance.
