  • Patent number: 10506748
    Abstract: A corona shielding system for an electric machine, for example a high-voltage machine, such as a generator, for generating electrical energy, an electric motor or else other electric operating means having a relatively high rated voltage, such as transformers, bushings, cables, etc, is disclosed. The corona shielding system may include a filler mixture including both planar and spherical particles. Therefore, the electrical conductivity, which is good in the presence of only planar particles in two spatial directions but is very poor in the third, can be adjusted anisotropically in a targeted manner.

  • Publication number: 20160290160
    Abstract: A turbomachine includes an inner housing which radially defines the flow channel of the turbomachine. A thermal barrier coating is arranged about the inner housing. The thermal barrier coating of the inner housing is made of microporous plastic coating which can be added to hollow spheres made of different materials and have different sizes. A method for applying a thermal barrier coating to the inner casing of a turbomachine includes preparing a material having a base material which has a microporous plastic; coating the outside of the wall of the inner casing by applying the base material to the inner casing; and curing the applied material, thus forming the thermal barrier coating.
