Designed to use for high-rise transmission lines, especially for EHV (500,000KV) transmission cables, river-crossing transmission lines to provide the warning marks
Item Name：Aviation sphere ball
Application：Applicable to electrical transmission lines, especially ultra-high voltage electrical transmission lines and cross-river electrical transmission lines, the shape of eye-catching aviation sign ball should be set on the line to provide aviation marks.
2. Features and Characteristic
Material：High strength fiber material.
? The colors or sphere marker ball: single red,white and orange or red/white,orange/white ect. Widely used high strength PC+fiber+ABS+Aluminum as the material,which it is lighter and high anti-corrosion.
? The aviation sphere mark ball are installed to the lightning protection ground wire of electrical transmission line.Every 30m distance to be set or fixed.
? In situations involving multiple wires,cables or other lines,the aviation sphere ball should be set at no less than the height of the highest overhead line where the markers are located.
3. Process Characteristics:
Using special manufacturing process technology,the aviation sphere ball has function of temperature resistance,waterproof,dust-proof,long lifespan.Especially the performance will not be changed under various complex environments and high strength of corrosion resistance.
Working environment temperature:-40℃ to 55℃.It can be worked other harsh environment.
