The coloured balls on overhead electricity cables act as visual warnings for low flying aircraft. They are most often used when cables cross major highways or deep gullies or valleys. To aid visibility, the colours are chosen to provide the greatest possible contrast with the background terrain.Click to see full answer. Also to know is, what are those balls on power lines for?They’re called visibility marker balls or marker balls. You’ll often find them near mountain passes, in the deep valley areas, near major freeway crossings and around airports. They weight about 17 pounds each. The marker balls are placed on power lines to make the conductor crossings visible to aircraft.Similarly, how big are marker balls? Marker Balls are typically used in airport and heliport approach areas and where power lines span long distances crossing canyons, lakes and rivers. The Model JX is available in four diameters: 9″, 12″, 20″ or 24″. Similarly, what are the spring looking things on power lines? Turns out, they’re called lightning arresters and they’re crucial to preventing certain blackouts.How do squirrels walk on power lines? Electrical Conductors When squirrels walk on power lines, electricity would not travel from one end of the wire to the other faster by traveling through the squirrel, so the electricity and squirrel both continue on their paths.
