MATERIAU ISOLANT POUR SURMOULAGE SUR APPAREILS MOYENNE ET HAUTE TENSION, ET APPAREILS ELECTRIQUES MOYENNE ET HAUTE TENSION UTILISANT UN TEL MATERIAU
摘要:
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 ε 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.
