Method for treating the surface of a wall in an electrical protection apparatus and apparatus comprising at least one wall treated according to said method

A method for treating a surface of a wall, that can reduce conductivity thereof, the surface being located in a first area located near a second area in which an electric arc is likely to occur in an electrical protection apparatus, the first area constituting an area for recondensing cutting residu...

Beschreibung
Zusammenfassung:	A method for treating a surface of a wall, that can reduce conductivity thereof, the surface being located in a first area located near a second area in which an electric arc is likely to occur in an electrical protection apparatus, the first area constituting an area for recondensing cutting residue. The method includes micro-texturizing the surface to promote inhomogeneity in recondensation of cutting residue, by growing deposits of the residue on the surface to create islands of residue and thus to restrict conductivity of the resulting deposit.
