  • Patent number: 9938405
    Abstract: An object of the present invention is to provide a hybridized insulating resin material, in which a viscosity is low to ensure a molding ability and the occurrence of voids is suppressed with respect to a resin material to which 2 to 20 wt % of fine particles of 100 nm or less are added, and a high voltage equipment including the hybridized insulating resin material. The object is achieved by providing a hybridized insulating resin material for a high 1.0 voltage equipment, which contains 2 to 20 wt % of fine particles having a particle size of 100 nm or less and contains a nonion surfactant having an HLB value of 2 to 8, and a high voltage equipment including the hybridized insulating resin material.
