Abstract (en)
[origin: FR2821479A1] The invention concerns an insulating material suitable for forming an over-moulding on a medium or high voltage appliance. The inventive insulating material comprises a mineral filler enabling electrical permittivity epsilon increasing with the applied electric field, in a proportion ranging between 5 and 50 % by volume, and a matrix suited for over-moulding, wherein said filler is dispersed. The invention is applicable to medium and high voltage circuit breakers.
