Why Aerial Marker Balls are Used in Transmission Lines ? | Dr. J. A. Laghari

in this video tutorial, why aerial marker balls are used in transmission lines is discussed ? These colorful balls hanging on the power transmission lines are known as Aerial Marker Balls or Visibility marker balls. These balls use four colors namely orange, yellow, white and red. They are mostly installed on those transmission lines which are located near hilly areas, at river crossings and near the airports. These marker Balls are used for safety. It saves lives and infrastructure by making power transmission and distribution line visible to the low flying helicopters, aircraft and aeroplanes.
