Abstract

L'invention concerne un papier synthétique pour l'isolement électrique à bain liquide, et son procédé de fabrication. Les fibres d'une couche non tissée de polyester sont enrobées dans du polypropylène résultant de la fusion d'une couche continue pressee contre cette couche non tissée, et il en résulte à la fois une diminution de la perméabilité du papier obtenu, et une amélioration de la tenue de ce papier au choc électrique lorsqu'il baigne dans l'huile Application à l'isolation des transformateurs à haute tension
