Abstract
A slide track mounting or a contact brush mounting for a sliding contact assembly comprises insulators having a surface structure that is a combined microstructure and nanostructure. Thereby an accumulation of dirt and abraded particles from contact brushes on the insulators is substantially reduced. This allows creep paths to be shortened and periods between maintenance operations for cleaning to be prolonged.
