Abstract
A current limiting high voltage fuse wherein a hollow body 1 has conductive caps 2, 3 at either end and is filled with silica sand. A plurality of fusible strips 8 extend between the two caps. Each fusible strip has a low melting alloy spot 10. The locations of the spots are staggered and are positioned substantially one third of the way along a respective fusible strip. In an alternative construction, the fusible strips 13, 14 are wound around a pair of coaxial formers 11, 12, with the fusible strips 14 wound around the central former 12 having a smaller cross section than the fusible strips 13 wound around the outer former 11.
