Abstract
The invention relates to an assembly for a current limiting high voltage fuse, comprising a preferably tubular support body (1), consisting of quartz glass, and fusible conductors (2) attached over their entire length to the support body, which conductors (2) are of a width of minimum 0.5 mm and maximum 1 mm and of a thickness of maximum 50 .mu.m. These fusible conductors are applied in parallel paths, the distance between the paths being at least twice as large as the width of the fusible conductors. Also the fusible conductors are provided with narrow sections (4) separated in longitudinal direction of the fusible conductor over regular distances, and interconnected at both ends by an electrically conducting sleeve (3) applied to the support body (1).
