Title:
ELECTRICAL INSULATING MATERIAL FOR HIGH-VOLTAGE DEVICES
Document Type and Number:
WIPO Patent Application WO/2017/098566
Kind Code:
A1
Abstract:
Provided is an electrical insulating material for high-voltage devices, which does not undergo the precipitation of an additive material contained therein and can achieve electrical properties and mechanical properties at the same levels or higher levels as or than those achieved by the conventional electrical insulating materials. The electrical insulating material for high-voltage devices according to the present invention is characterized by comprising: a resin (3); and additive materials (1, 2) and microparticles (4) all of which are dispersed in the resin (3). The electrical insulating material is also characterized in that each of the microparticles (4) has the same main backbone as those of the additive materials (1, 2), the average particle diameter of the microparticles (4) is 1 to 200 nm, some of atoms constituting the main backbone are respectively bonded to organic groups and inorganic groups, and the microparticles (4) are located surrounding the additive materials (1, 2).
