CA 2502595

The present invention relates to a field grading material consisting of a polymeric matrix provided with a filler. The filler comprises a field grading effective amount of particles having at least one dimension smaller than or equal to 100 nm. The invention also relates to a device comprising such a field grading material for grading an electric field in high-voltage applications and a method for grading an electric field at a joint or termination of an electric power cable using such a field grading material.

La présente invention porte sur un matériau de transformation d'un champ électrique qui comprend une matrice polymère pourvue d'une charge. La charge comprend une quantité effective de particules pour la transformation du champ, la dimension des particules étant au moins inférieure ou égale à 100 nm. L'invention porte également sur un dispositif comprenant ce matériau de transformation de champ qui permet de transformer un champ électrique dans des applications haute tension, et sur un procédé de transformation d'un champ électrique au niveau d'un raccordement ou d'une extrémité d'un câble électrique constitué de ce matériau de transformation de champ.
