Abstract

A current collector for a rail-mounted vehicle includes a collector arm and an insulation system which has insulating posts for the electrically insulating fastening of the collector arm on a vehicle roof element above an electrically grounded roof surface. In order to achieve a flatter roof structure, the insulation system includes an electrically insulating layer, which is disposed between the roof surface and the collector arm and is spaced apart from the roof surface by an air gap.
