Insulating bearing element or insulating screen, in particular insulating partition for directly mounted electrodes or voltage-carrying parts or such electrodes or parts sited at a certain distance therefrom

摘要

To achieve a high surge voltage strength without impairing specified mechanical properties, an insulating bearing element for electrodes in high-voltage appliances is of at least two-layer construction. At least one layer forms the base and the additional layer has a lower permittivity than the material used for the base. The additional layer may be very thin and applied in the form of a paint or a foil.
