ABSTRACT:
The invention relates to an equipment for the maintenance and particularly for the washing of insulator chains supporting high voltage electric lines, which allows operation on a live line. The washing of the insulator chain is performed through jets of washing fluid sprayed in close proximity to and over the whole contour of the insulators. The equipment comprises a guide body movable along the insulator chain, a plurality of washing liquid spraying nozzles mounted on said guide body, and moving means to guide said body along the insulator chain. This moving means consists of at least one track, rotating on two transmission rollers, at least one of these rollers being motor-driven and the active section of the track being in contact with the peripheral edge of the insulators of the chain. According to the invention, the guide body surrounds the insulator chain, at a short distance from the same insulators; the track presents a plurality of tongue teeth, projecting perpendicularly from its outer surface. The assembly of guide body and track has a plurality of contact points with the periphery of each insulator, distributed over the whole contour of the same insulators.
