名称：Transmission Line Aerial Marker Ball
型号：
Aviation warning spheres for transmission lines serve as critical safety devices on power lines. Constructed from engineering-grade reinforced plastic in highly visible colors such as red, white, and orange, they effectively capture pilots' attention. Installed on high-voltage transmission lines—particularly ultra-high-voltage and river-crossing lines—they provide clear visual warnings for low-flying aircraft, preventing collisions between the spheres and high-voltage conductors.

I. Requirements Analysis
Overhead transmission lines play a vital role in power systems as the infrastructure enabling long-distance electricity transmission. However, their presence also poses a significant safety threat to aircraft flying at low altitudes. If an aircraft lacks sufficient altitude or distance, or fails to recognize the location of transmission lines, collisions between aircraft and power lines may occur. To prevent such incidents, aviation warning spheres must be installed on transmission lines, providing visual safety warnings for pilots flying at low altitudes.
II. Working Principle
The aerial marker ball for transmission lines is an innovative device widely used on high-voltage transmission lines, particularly on ultra-high-voltage and river-crossing transmission lines. Its primary function is to provide warning, enabling pilots to clearly identify its location from 1 to 2 kilometers away. This allows them to recognize the presence of high-voltage conductors and promptly avoid potential safety risks. The introduction of this device not only enhances flight safety but also effectively prevents the safety hazards that could arise from aircraft collisions with high-voltage power lines.
III. Product Features
1. Ideal for overhead transmission lines near airports, as well as ultra-high voltage (220kV and above) transmission cables and river-crossing transmission cables;
2. Premium raw materials, including high-quality fiberglass and resin, ensure corrosion resistance, high-temperature tolerance, electrical insulation, rustproofing, dustproofing, waterproofing, and superior impact resistance.
3. Colors are customizable, including white/red/orange/orange-white two-tone/orange-red two-tone, etc.
4. Easy and quick installation—simply hang it on the conductor wire, with no maintenance required afterward.
5. While resisting interference, it does not interfere with the normal operation of high-voltage conductors.
6. Highly adaptable, maintaining consistent performance under complex environmental conditions such as wind, frost, rain, snow, and high temperatures.
