    Abstract: Electrical contact system with a first and a second contact (1, 5), each having a contact surface (4, 8). The first electric contact (1) has a mesostructured electric contact portion (14) with a plurality of slots (15) and ridges (16) formed between neighboring slots (16) of the plurality of slots (16). These slots (15) and ridges (16) extend in a direction running transversely to said switching plane (X-Z) form a plurality of current paths (16). The current paths (16) are inclined to the first contact surface (4) at a first angle (17) measuring less than 60 degrees such that an interruption current (12) flowing through the mesostructured electric contact portion (14) and through an electric arc (11) extending in between the first contact surface (4) after lifting the first contact surface (4) off the second contact surface (8) pushes said electric arc (11) in the direction of the apex of said first angle (17) from a first position (18) to a second position (19).

    Abstract: A bushing for high voltage applications comprises a conductor surrounded by at least one foil (22) of conductive material, where the foil has an edge over which a layer (26) of semiconductive paint stretches. The semiconductive paint comprises flakes of thermally reduced graphene oxide as a field grading material having a conductivity that varies with electrical field strength. The layer (26) has a thickness and the flakes have at least one width, where the thickness is smaller than the width.
