Abstract (en)

[origin: WO2020193323A1] The invention relates to a novel composition of a casting resin and to the use thereof in hot-curing electrical potting, as used for example in the production of insulation, for example for gas-insulated switchgears, electrical components such as transformers, insulators, capacitors, coils and modules. The invention also relates to a moulding material which is obtainable from the casting resin, to electrical insulation which comprises this moulding material, and to the use of such a moulding material. In particular the tetramodality of the microfillers used together with the average particle sizes classified into decimal powers results in an excellent packing density and exhibits surprisingly good workability and flow behaviour at the highest filler contents up to 95 wt%. With the invention, it is possible for the first time to use such high-filler and thus highly thermally conductive casting resins in the aforementioned systems for automatic pressure gelation processes and/or in a (vacuum) circulation casting system.
