Abstract (en)
[origin: WO2020016525A1] The invention relates to a composite electrical insulation material (1) comprising an epoxy matrix (2) of cycloaliphatic type or of diglycidyl ether type, and from 15 to 45% of fillers, including a first micrometric inorganic filler (3) having an aspect ratio of less than 3 and a lamellar second micrometric inorganic filler (4) in a volume ratio ranging from 95/05 to 40/60. The invention also relates to the process for manufacturing such a composite electrical insulation material (1), and also to the use thereof for electrically insulating supports (9) in a metal-enclosed substation (5).
