Abstract (en)
[origin: WO2020025410A1] The invention relates to a make contact system for high-voltage applications, characterized in that a vacuum switching tube (28) having two switch contacts in the form of plate contacts (2, 4) is provided, of which at least one is a moving contact (30) coupled to a drive (5), and whereby at least one plate contact (2, 4) is rotationally symmetrically surrounded by a shielding element (32), and the shielding element (32) has an electric conductivity which is less than 40 10-6 S/m.
