Abstract (en)
[origin: EP2533251A1] An electrical insulating material excellent in crack resistance properties without deteriorating the properties of an insulating resin in a solid insulation system, and a high voltage equipment using the same are provided. An electrical insulating material comprising: an epoxy resin; a curing agent; and an elastomer particle (3) and an inorganic particle (2) as an additive material, wherein at least a part of the elastomer particle (3) is radiation cross-linked. A high voltage equipment such as a transformer, a circuit breaker, a motor, and an inverter, in which this electrical insulating material is applied at a site requiring an electrical insulation of an electrical equipment.
