The invention concerns an insulated high voltage overhead power line, which comprises at least three conductors 2, 3, 4 covered with an insulating layer. In order that trees which have fallen over the insulated high voltage overhead power line can be detected without any of the phase leads 2, 3, 4 being switched off, the thickness of the layer of insulation of one conductor 3 in the overhead power line 1 is at least 20% less than the thickness of the insulation layer on the other conductors 2, 4, in the power line 1. <IMAGE>
