METHOD FOR LUBRICATING A CABLE OR WIRE OF AN OVERHEAD POWER LINE AND A DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2022 - IPC B61B12/08 B66B7/12 B64C39/02 

FIELD: electric power industry.

SUBSTANCE: invention relates to the electric power industry. A device for lubricating a cable or wire of an overhead power line is an unmanned aerial vehicle, containing a means for moving along a cable or wire (1) and a lubrication chamber (2) installed on it, the lower part (3) of which is movable with the possibility of opening for opening cable or wire (1) inside the chamber. In the lubrication chamber (2) nozzles (4) are installed, to which a hose (5) is connected with a shut-off and control valve for supplying lubricant from a tank installed on the unmanned aerial vehicle. A hose (7) is also connected to the lubrication chamber (2) to drain the lubricant from the lubrication chamber back to the tank. The lower part (3) of the lubrication chamber (2) is equipped with a recovery filter (9) to clean the lubricant when it is removed. The connector between the upper and lower parts of the lubrication chamber is made inclined.

EFFECT: simplification of the design of the lubrication chamber, improvement of quality, elimination of leakage of lubricant into the environment.
