Title (EN) ELECTRIC INSULATOR AND A METHOD FOR THE PRODUCTION THEREOF
(FR) ISOLATEUR ELECTRIQUE ET PROCEDE DE FABRICATION.
Abstract:
(EN) The invention relates to an electric insulator (1) comprising a tube (3) surrounded by an insulating smooth or provided with fins (7) jacket (5). The insulating jacket is made of an epoxy resin comprising 25-75 % by weight mineral filler. The inventive method for producing said electric insulator consists in placing the insulator tube or the precursor thereof in the electric insulator mould possibly provided with fins, in introducing an unhardened cycloaliphatic epoxy resin into the mould in such a way that the insulator jacket and fins are formed around said tube or the precursor thereof, in hardening the resin introduced into the mould in such way that the insulator is produced and in removing the thus produced insulator from the mould. The inventive electric insulator is suitable for high voltage application.
(FR) La présente invention se rapporte à un isolateur électrique (1) comprenant un tube (3) entouré d'une gaine isolante (5) lisse ou munie d'ailettes (7) . La gaine isolante est constituée d'une résine époxyde cycloaliphatique hydrophobe chargée comprenant de 25 à 75 % en poids de charge minérale. Le procédé de fabrication de cet isolateur comprend les étapes consistant à mettre en place le tube de l'isolateur ou un précurseur de celui-ci dans un moule à isolateur électrique comportant éventuellement des ailettes, à introduire dans le moule la résine époxyde cycloaliphatique non durcie de manière à former la gaine et les ailettes de l'isolateur autour dudit tube ou de son précurseur, à durcir la résine introduite dans le moule pour obtenir l'isolateur, et à extraire du moule l'isolateur obtenu. L'isolateur électrique de l'invention est utilisable à haut voltage.
