The method involves using a cast resin e.g. epoxy resin, for electrical isolation of a coil body of a cast resin transformer. A tenacity modifier such as an acrylonitrile copolymer and/or a silicone rubber, is added to a liquid cast resin, where a composite liquid cast resin serves for grouting the coil body. The poured coil body is warmed up for hardening at increasing temperature. A catalyst such as tertiary amine and/or a quaternary ammonium composite, is added to the liquid compound cast resin. An amorphous quartz powder acting as filler is added to the liquid cast resin. An independent claim is also included for a cast resin transformer with an electrical isolation of a coil body. |
