Transmission tower obstruction lighting reference configuration
● Transmission towers generally use Type B medium-intensity obstruction lights.
● Install obstruction lights at three levels: the tower top, the lowest point of the suspended cable and the midpoint of the suspended cable.
● All obstruction lights on the same tower should flash synchronously or sequentially.
● Install warning spheres at equal intervals on overhead cables, no more than 30 m apart.
● Most transmission-tower obstruction lights use solar power systems.
