ABSTRACT:
A high voltage fuse comprised of a fuse element wrapped about a core, enclosed in a housing member, and surrounded by a granular quartz material is disclosed. The core has a plurality of cutouts along its outer surfaces having preselected dimensions relative to the width of a fuse element of such values as to assure that at least one cutout is interposed between adjacent turns of the fuse element. The interposed cutouts increase the creepage between the adjacent turns of the fuse element. The preselected dimensions of the cutouts relative to fuse-element width provide a single core that is capable of accommodating numerous types and different numbers of fuse elements. The core is also provided with a gas evolving material attached to the cutouts and separated from the fuse element by a predetermined amount to provide controlled release of arc-quenching gas, when arcing inside the fuse occurs.
