ABSTRACT:
A method and apparatus for cable support and guidance for use on a high elevation outdoor lighting system in which luminaires, for servicing and inspection, are lowered from an operating position at the top of a pole to a position at the base of the pole. A series of rollers are mounted at the pole top to support and guide the passage of a luminaire, elastomer-jacketed power cable which, during raising and lowering of the luminaires, moves in a path that extends vertically through the interior of the pole, over the roller arrangement and vertically to the luminaires on the exterior of the pole.
