Graphite layer application on cable insulation - involves series of rotating drums containing powder and several smoothing devices

摘要

The graphite layer is continuous and conducting, and the powdery material (graphite) is applied dry. The powdery material (10) is applied on the continuously moving cable (8) in drums (1) and then distributed on the surface and/or rubbed into it. The applied layer is smoothed in the peripheral direction. The application and rubbing in of powder is at least once repeated in the longitudinal direction, and smoothing in the peripheral direction.
